PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 13 Safety instructions 2.3 Hazards during handling and installation 2.3 Hazards during handling and installation Improper handling and installation of certain parts and components can result in injury under unfavorable conditions. CAUTION Danger of injury due to improper handling! Injury by crushing, jackknifing, cutting, bumping, or lifting! * The general construction and safety regulations must be observed in handling and installation. * Each cabinet section weighs more than 1,000 kg. * Suitable installation and transport equipment must be used. Read the specifications and safety information of the chapter Application planning (Page 81). * Only use suitable tools. * Lifting equipment and tools must be used correctly. * Suitable protective equipment (e.g. safety goggles, safety shoes, protective gloves) must be used. * Never stand underneath suspended loads. 2.4 Hazards in photovoltaic plants Below are listed some typical special features and hazard sources in photovoltaic plants: Since the short-circuit current only slightly exceeds the maximum operating current, there is no clear guarantee that the available fuse will trip in the event of a short-circuit. Depending on the operating status, the plant can still be under power from the PV generator via the SINVERT PVS inverter even when it is switched off. This must be remembered when isolating the plant or sections of the plant. The PV generator is usually configured as an IT system without grounded transformer. A ground fault generates a fault message. In an IT system, there is no immediate danger of electric shock if no further fault occurs. Despite this, the ground fault must be corrected as quickly as possible by qualified personnel. PVS 600Series 14 Operating Instructions, 08/2014, A5E03467293-003 Safety instructions 2.5 Incorrect grid monitoring parameters 2.5 Incorrect grid monitoring parameters NOTICE Withdrawal of operating permit If you operate the SINVERT PVS inverter with the wrong grid monitoring parameters, the electrical utility can withdraw your operating permit. The device must therefore only be commissioned by authorized service personnel. The system settings must be adapted to local requirements regarding grid monitoring parameters. We assume no responsibility for incorrect grid monitoring parameters. 2.6 Possible safety gaps in the case of standard IT interfaces In SINVERT inverters, extensive parameterization and diagnostics functions are provided via open protocols and interfaces (e.g. Web server, network management). The possibility of unauthorized misuse of these open protocols and interfaces by third parties, for example to manipulate data, cannot be entirely excluded. When using the functions listed above and these open interfaces and protocols (for example, SNMP, OPC, HTTP), you should take suitable security measures to prevent unauthorized access to the components and the network, particularly from within the WAN/Internet. NOTICE We expressly point out that the inverter network must be isolated from the rest of the company network by suitable gateways (for example, field-proven firewall systems). We do not accept any liability whatsoever, whatever the legal justification, for damage resulting from non-adherence to this notice. If you have questions on the use of firewall systems and IT security, please contact your local Siemens office or representative.

Note The PV array must be connected for this purpose in 3 sub-arrays with the same total current and voltage values. The 3 inputs on the DC side are equipped with LV HRC fuses and DC contactors. This combination can be used to disconnect the inverter from the PV side. AC filters are used to smooth the AC output voltage. The AC output must be connected directly to the medium-voltage transformer for galvanic isolation. This is required at the AC output of every inverter subunit. A contactor and circuit breaker are used to disconnect the unit from the AC grid. Overvoltage protection devices are installed on the AC and DC sides. To increase efficiency and reduce no-load losses, up to four inverters can be interconnected in master/slave operation.

Remember: For the latest information about the necessity for and type of grounding, please contact your module manufacturer! Some module manufacturers recommend positive or negative grounding of the PV generator when certain types of module are used! PV systems no longer constitute a DC IT system when their modules are grounded. For safety reasons, the PV system must be fenced in and designated as an electrical operating area. Access must be prohibited to all persons except qualified electricians. Positive-pole grounding Grounding an active conductor (positive pole) means that the inverter's insulation measuring function no longer works in the normal way. A hazardous current can start to flow as soon as the first insulation damage occurs. For this reason, the condition of the system is monitored through measurement of the current between the positive pole and ground. If the current level measured is deemed to pose a risk (current value is parameterizable), the connection is automatically broken by means of a motor-operated DC disconnector. This DC disconnector is driven by the inverter's control system. In this context, it is important to note that the connection between the module array and inverter ground must be of high quality. If the connection resistance is high as a result of very dry conditions or unfavorable ground conditions, a sufficiently high current will not flow. It is also important to note that a fault at the same potential when grounded will not drive a current. The DC disconnector has three settings: Remote triggering Local operation "Off signal" position, lockable PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 29 Description 3.5 Inverter options Negative-pole grounding Grounding an active conductor (negative pole) means that the inverter's insulation measuring function no longer works in the normal way. A hazardous current can start to flow as soon as the first insulation damage occurs. For this reason, the condition of the system is monitored through measurement of the current between the negative pole and ground. If the current level measured is deemed to pose a risk (current value is parameterizable), the connection is automatically broken by means of a motor-operated DC disconnector. The disconnector is driven by the inverter's control system. In this context, it is important to note that the connection between the module array and inverter ground must be of high quality. If the connection resistance is high as a result of very dry conditions or unfavorable ground conditions, a sufficiently high current will not flow. It is also important to note that a fault at the same potential when grounded will not drive a current. The DC disconnector has three settings: Remote triggering Local operation "Off signal" position, lockable 3.5.2 Increase in max. DC voltage to 1000 V Areas of application and use The "1000 V option" increases the maximum DC no-load voltage for inverters to DC 1000 V. This ensures that the photovoltaic system can also operate with a (no-load) voltage of up to DC 1000 V, for example when operating on cold days. The profitability of the equipment is maximized as more modules can be connected in series, without affecting the ability of the PVS inverter to switch on. When will the equipment operate at no load? No-load operation will happen at the following times: Before switching on the PV inverter After switching off the PV inverter Standard response of the PVS inverter without the "1000 V option" The PV inverters of the PVS series feature a switch-on voltage of max. 820 V DC as standard. If the DC voltage is above 820 V, the SINVERT PVS PV inverter will not switch on. The 1000 V option allows the switching on and off of the SINVERT PVS PV inverter for PV field no-load voltages of up to 1000 V DC. PVS 600Series 30 Operating Instructions, 08/2014, A5E03467293-003 Description 3.5 Inverter options Switching on the PV inverter with "1000 V option" Switching on the PVS allows a variable voltage divider, consisting of series and parallel resistors, to activate the inverter DC link (without closing the DC input contactors). Thus only the required fraction of the PV field no-load voltage is present at the DC link, and not the entire PV field no-load voltage. The upstream measurement of the PV field voltage (Upv) is carried out in each individual inverter subunit. Only when the PVS SINAMICS power unit is operating and the AC main contactor is closed do the DC power contactors close in succession. Switching off the PV inverter with "1000 V option" When switching off the last (of max. four) PV inverter subunits in normal operation, the DC power contactors are first opened in succession, before the SINAMICS power unit of the inverter subunit is switched off and the AC contactor opened. During normal operation this ensures that the PV field no-load voltage is not present at the DC link. Unintentional disconnection of the PV inverter with "1000 V option" During operation of the PV inverter, situations may arise which lead to the PV inverter and the power unit to be switched off unintentionally. In such cases it is not always possible to successively or immediately switch off the DC power contactors prior to switching off the power unit, or they are switched off too slowly, to prevent the DC link voltage rising to impermissible values. In such cases, to protect the DC link against voltages which are too high, the following components are used: 1000 V special chopper Chopper resistor Crowbar 3.5.3 Cabinet heating Heating elements are integrated into the inverter to prevent condensation and if atmospheric humidity is too high. These heating elements are controlled by a hygrostat. 3.5.4 Symmetry monitoring The symmetry monitoring option measures the scaled currents within the inverter at the DC inputs and compares the values with each other. If this comparison indicates deviations over time, a message is generated. The message can be used for early detection of faults in parts of the photovoltaic field (e.g. cell failure).

The BDEW guideline "Generating Plants in the Medium-Voltage Grid" stipulates this requirement for all systems feeding in at the medium-voltage level. Its primary benefit is that it enables grid operators to limit the output of the plant by remote control in accordance with 6 of the Renewable Energy Sources Act 2009.

Parameterization of the functions using the SINVERT PVS ControlBox The SINVERT PVS ControlBox is used to control the SINVERT PVS inverters of a PV plant. You can find more information in the SINVERT ControlBox operating instructions on the Internet in the Industry Online Support (http://support.automation.siemens.com). Note SINVERT PVS ControlBox If communication between the SINVERT PVS ControlBox and the SINVERT PVS inverter fails, the SINVERT PVS ControlBox generates a fault message that is sent to the Scada system. The SINVERT PVS inverter continues to operate with the specifications it had before the communication failure. PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 35 Grid management 4.1 Grid management in the case of SINVERT PVS Technical requirements of the inverter The grid requirements are divided into static grid support, decoupling protection, and dynamic grid support. To meet the requirements of grid operators, you also require a plant controller such as a SINVERT PVS ControlBox, in addition to the functions in the SINVERT PVS inverter. The following static grid support functions are fulfilled by SINVERT PVS: Function Inverter ControlBox Static grid support Active power control * To fixed setpoint * According to frequency P = f(f)1) * According to output voltage P = f(U) - * Active power limitation during the switch-on operation - * By means of signals from the power utility - Reactive power control * To absolute Q setpoint - * To relative Q setpoint * To absolute cos setpoint * According to time of day Q(t)2) * By means of cos (t) according to time of day2) * According to output voltage Q = f(U)2) * According to cos (P)2) * By means of signals from the power utility - Frequency monitoring - Voltage monitoring - Feed-in conditions - Low voltage ride through (LVRT) - High voltage ride through (HVRT) - Fault ride through (FRT) - Decoupling protection Dynamic grid support 1) The function must only be activated either in the inverter or in the ControlBox. 2) If a ControlBox is used, the function must be deactivated in the inverter.

Settings You set the individual active power control functions under the Service menu item "Grid Parameters Menu". Figure 4-2 Grid Parameters Menu The menu item "P & Q Control" contains the settings for the following control conditions: Active power control to fixed setpoint (Page 39) Active power control in accordance with output voltage P = f(U) (Page 45) You will find the settings for the Active power control during the switch-on operation (Page 46) under the menu item "Active Power Ramps". You will find the settings for the Active power control according to frequency P=f(f) (Page 40) under the menu item "Frequency Derating". PVS 600Series 38 Operating Instructions, 08/2014, A5E03467293-003 Grid management 4.2 Static grid support 4.2.1.1 Active power control to fixed setpoint Function The active power of the SINVERT PVS inverter can be limited to a fixed setpoint Pmax. The setting is made as a percentage of the maximum rated power. This function is also used by the SINVERT PVS ControlBox to implement the grid operator's specifications. Note SINVERT PVS ControlBox When using the SINVERT PVS ControlBox, this value is overwritten cyclically. Settings Figure 4-3 P & Q control [1/9] Figure 4-4 P & Q control [3/9] PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 39 Grid management 4.2 Static grid support You activate or deactivate the active power control to a fixed setpoint using the following three parameters: Parameter number Parameters Range Increment 33837 Activation 1 of Pmax controller On - 33838 Activation 2 of Pmax controller On Off - Off For activating the active power control to a fixed setpoint, both parameters must be set to "On". For "Active power control to fixed setpoint", enter the setpoint in the field p32828. 4.2.1.2 Function Parameter number Parameters Range Increment 33828 P relative 0 ... 100% of the rated power 1% Active power control according to frequency P=f(f) If the power grid contains more power than is currently used, the grid frequency increases. The SINVERT PVS inverters detect an increase in the grid frequency and can reduce the active power dependent on frequency. The relationship between the output power and the grid frequency is predefined via the P(f) curve. If a parameterized frequency value f1 is exceeded, the active power Pf present at this time is registered and thereafter used as the reference value for the P=f(f) curve. While the frequency in the grid increases, the SINVERT PVS inverter supplies an output power dependent on the level of the current frequency along the curve. The rise in the PP=f(f) curve can be parameterized on the inverter by means of the gradient G. If the frequency exceeds a parameterized frequency limit fH, see Chapter Frequency monitoring (Page 74), the SINVERT PVS inverter switches off. Figure 4-5 Active power control according to frequency P=f(f) PVS 600Series 40 Operating Instructions, 08/2014, A5E03467293-003 Grid management 4.2 Static grid support Resumption of normal operation: There are three modes of resuming normal operation in the the case of frequency derating: 1. Frequency derating without hysteresis Figure 4-6 Active power control according to frequency P=f(f) without hysteresis As long as the frequency does not drop below the limit f1 again, the SINVERT PVS inverter supplies an output power dependent on the level of the current frequency along the curve. As soon as the frequency drops below the limit f1 in the grid, the SINVERT PVS inverter resumes normal operation. It now feeds in the maximum possible power again, provided no other specifications are present. 2. Frequency derating with hysteresis and start frequency Figure 4-7 Active power control according to frequency P=f(f) with hysteresis and start frequency If a second limit frequency f2 (parameterizable) is exceeded, the inverter no longer follows the curve, and instead remains at a constant output power Pf2(determined by the curve) until the frequency has dropped below the end frequency for resuming normal operation f3 (parameterizable).

Frequency derating with hysteresis and without start frequency Figure 4-8 Active power control according to frequency P=f(f) with hysteresis and start frequency Contrary to active power control according to frequency P=f(f) with hysteresis and start frequency, the second limit frequency f2 is not required. The inverter generally no longer follows the curve in the case of frequency derating, and instead remains at the minimum calculated output power P (determined via the curve) until the final frequency for resuming normal operation f3 (parameterizable) has been undershot. Only one mode is parameterized for frequency-dependent active power reduction. You set all parameters here, regardless of which mode is used. Parameterization of a minimum holding power A minimum holding power can be parameterized additionally for modes 1 and 3. Some Grid Codes demand this. If this function is activated, the inverter will not reduce the output power below the parameterized holding power. If the frequency f nevertheless continues to rise, the inverter will be switched off when the frequency point fH is reached. Note The functions can be deactivated if required.

The following options can be parameterized to stipulate when the output is to be increased via a ramp: Never Only following grid fault At every start operation The increase of the ramp over a gradient until the full rated active power Pn is reached can continue to be parameterized. The increase in the ramp is independent of the actually present active power. The active power increases along the ramp up to the existing PV array power.

It is possible to influence the grid voltage by means of the reactive power. The SINVERT PVS inverters can be operated with a reactive power corresponding to a power factor cos = 0.8 inductive (low voltage / medium voltage) to cos = 0.8 capacitive. Note Negative values correspond to an inductive reactive power (overexcited operation) and positive values to a capacitive reactive power (underexcited operation). Reactive power control can be specified in accordance with five different functions: Reactive power control to absolute setpoint of Q or cos Reactive power control according to time of day Q(t) or cos (t) Reactive power control according to output voltage Q=f(U) Reactive power control according to active power cos (P) Reactive power control to relative fixed setpoint of Qmax In general, a distinction must be made between two different bases when providing reactive power: Reactive power control on the basis of the power factor cos Reactive power control on the basis of reactive power Q Different functions are available depending on the basis selected. Reactive power control on the basis of the power factor cos For power factor cos (setpoint type), you can select one of the following functions (setpoint source): Fixed setpoint cos (P) curve cos (t) curve Note SINVERT PVS ControlBox When using the SINVERT PVS ControlBox, the function "Fixed setpoint" must be selected since the fixed setpoint is specified by the SINVERT PVS ControlBox.

The SINVERT PVS inverter has the ability to withstand brief voltage dips and remain on the grid. The shutdown behavior in the case of voltage dips can be set via the LVRT curve, see the chapter "Shutdown behavior in the event of voltage dips (Page 64)". The SINVERT PVS inverter can continue to provide reactive current for voltage support during these voltage dips. The level of the reactive current can be set via the k factor depending on the depth of the grid voltage dip, see the chapter "Reactive current provision in the event of voltage dips (Page 67)". 4.3.2 Function Shutdown behavior in the event of voltage dips The LVRT curve can be parameterized by means of up to 10 interpolation points. An interpolation point consists of a voltage level U / Un and a time t during which the voltage level can be present before the SINVERT PVS inverter shuts down. Linear interpolation is carried out between the two interpolation points. The voltage level is calculated from the ratio of the actual voltage U to the rated voltage Un.

For this reason, parameterize two of the interpolation points identically to the entered limit values of the undervoltage monitor. See Chapter Voltage monitoring (Page 76). When parameterizing, all fields must be filled, but it is not absolutely necessary to use all available interpolation points. When using fewer than 10 interpolation points, the order of the entered interpolation is decisive since interpolation between the individual points is linear. For this reason, always enter the used interpolation points first. Then enter the values of the last interpolation point in the subsequent fields for the interpolation points that are not required. You will find an example in the figure below. The first four interpolation points (0 to 4) are used. All the subsequent fields (5 to 9) for the unused interpolation points are parameterized in the same way as the last interpolation point.

The level of the reactive current IB / In additionally fed in when a fault occurs results from the depth of the grid voltage dip U / Un and the k factor. No more than the rated current In can be fed in. During the voltage dip, as much active power as possible continues to be fed in. In addition, the SINVERT PVS inverter has "Zero power mode". If this mode is set, the SINVERT PVS inverter remains on the grid for the parameterized time but feeds neither active nor reactive power into the grid. "Q mode" is another mode. If this mode is set, the SINVERT PVS inverter remains on the grid for the parameterized time and feeds pure reactive power into the grid. In "Standard mode" as well as "Q mode", the reactive current response can be be set not only via the k factor, but also via "Advanced mode". In this mode, it is possible to parameterize a Q=f(U) characteristic freely for LVRT.

The shutdown behavior in the case of voltage rises can be set via the HVRT curve, see the chapter "Shutdown behavior in the event of voltage rises (Page 69)".

If the limits are violated for an adjustable time, the inverter disconnects from the grid. 4.4.2 Frequency monitoring Function The SINVERT PVS inverter monitors the grid frequency during operation. If a certain frequency range is exceeded or undershot, a grid fault can be assumed, and shutdown of the SINVERT PVS inverter is necessary. Up to six parameterizable limits for both overfrequency and underfrequency are available for shutdown outside the permissible frequency range. A frequency and a tripping delay time can be parameterized for each limit. If the grid frequency is outside the parameterizable range, the SINVERT PVS inverter shuts down, and a fault message is output. As soon as the grid frequency returns to the permissible range, the fault message is automatically acknowledged. If the grid is within the specified limits for restarting, see the chapter "Feed-in conditions (Page 79)", the inverter powers up again automatically.

The delay is the minimum time for which a fault must be active to effect shutdown.

The required limit values for overfrequency/underfrequency refer to the rated grid frequency of the inverter. When parameterizing, all fields must be filled, but it is not absolutely necessary to use all available interpolation points.

If the grid is within the parameterized limits, and if all restart conditions have been met, the inverter powers up again automatically. The voltage limits are input as a percentage of the rated voltage; the frequency limits are input as a percentage of the rated frequency (50 / 60 Hz). Note The connection conditions range must be smaller than the shutdown conditions range to avoid the constant on and off switching of the inverter when operating in limit ranges of the permissible rated voltage/frequency. You will find further information on the shutdown conditions in the chapters "Frequency monitoring (Page 74)" and "Voltage monitoring (Page 76)". Settings Figure 4-49 Low voltage [5/5] The function can be set via the following parameters: Parameter number Parameters 32682 Undervoltage limit Range Increment 80 ... 100 % 0.01 % of the rated voltage 32683 Overvoltage limit 100 ... 115 % 0.01 % of the rated voltage 32685 Underfrequency limit 32686 Overfrequency limit 90 ... 100 % 0.01 % of the rated frequency (50 / 60 Hz) 100 ... 103 % 0,01 % of the rated frequency (50 / 60 Hz) PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 79 Grid management 4.4 Decoupling protection PVS 600Series 80 Operating Instructions, 08/2014, A5E03467293-003 Application planning 5 The following chapter contains detailed information about packaging, dispatch, delivery, storage, transport, installation location and configuring.

Please also note the safety notice regarding the risk of tipping if the pallet and cabinet are not mechanically connected. Figure 5-3 Transport packaging - Mechanical connection with the transport pallet WARNING Danger to life through tipping due to lack of mechanical connection with the pallet The cabinet may be transported only if it is securely mechanically coupled with the pallet (strapping and bolting). If the load is not securely coupled, it can tip or fall off the pallet. In this case, the high weight mass of the cabinets can cause serious injuries, death and substantial property damage. PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 85 Application planning 5.2 Transport Danger of tipping of the transportation unit WARNING Danger to life from tipping! A cabinet, whether with or without pallet, must never be tipped in any direction. The cabinet is very heavy. Tipping it too far and causing it to topple over can therefore result in serious injury, death and substantial property damage. Figure 5-4 Impermissible tipping of cabinets and pallets PVS 600Series 86 Operating Instructions, 08/2014, A5E03467293-003 Application planning 5.2 Transport Mechanical connection between the inverters The SINVERT inverter is transported in two consignment units or cabinet sections. No provision is made for transporting connected cabinet sections. Figure 5-5 Impermissible transport of two cabinet sections The inverter cabinet sections must never be transported once they have been assembled into a single unit. WARNING Danger to life from transport of assembled cabinet sections! Owing to their design, cabinet sections must never be transported once they have been mechanically assembled into a single unit. Cabinet sections must always be transported as a single unit by one of the permitted methods of transport. The heavy weight of the cabinets means that they can cause serious injury, death and substantial property damage if incorrectly handled. Locking of the doors The doors on the cabinet sections are closed by Siemens prior to dispatch. Keep these doors closed and locked at all times during transportation. The door locks are secured against accidental unlocking by means of small plastic caps. The plastic caps must be removed when the consignment is positioned at the final installation location.

It is absolutely prohibited to transport the inverters on crane eyelets or steel lifting elements. If excessive mechanical stress causes the load to fall off the crane, there is a risk of serious injury, death or substantial property damage. WARNING Danger to life from impermissible attachment of ropes along vertical sides of load! The cabinets are not designed to be transported by crane from ropes attached along the vertical sides of the load. This method of transport is expressly prohibited. If excessive mechanical stress causes the load to fall off the crane or to tip, there is a risk of serious injury, death or substantial property damage. PVS 600Series 92 Operating Instructions, 08/2014, A5E03467293-003 Application planning 5.2 Transport 5.2.4 Transport and alignment of cabinets in electrical operating areas Removing the transport locks The cabinets are attached to the pallet by means of transport locks (upward-facing screws). 1. To lift the cabinets off the pallet, you first need to undo the screw nuts. 2. To slide the cabinets off the pallet, you need to push the screws out downwards far enough (e.g. using a hammer and a thick nail), so that the surface of the pallet becomes smooth. Moving the cabinet off the standard pallet All cabinets can be moved on rollers placed under the cabinet frame. As rollers, you should use solid metal rods with a length of 20 cm and a diameter of 2 cm. Figure 5-10 Moving the cabinet off the standard pallet Use a crowbar to lift the cabinet so that you can place the rollers under the frame. If you want to change the rolling direction, you must lift the cabinet again, turn the rollers by 90 and place them under the frame again. You may need to strengthen the floor with metal sheets before you move the cabinets over it. Make sure that the metal sheets are placed such that you will be able to remove them again once the inverters have been installed. In order to move or roll the cabinet off the pallet, you will need a solid metal bar or a strong pipe of 100 cm in length and 6 cm in diameter. PVS 600Series Operating Instructions, 08/2014, A5E03467293-003 93 Application planning 5.2 Transport Procedure 1. Adjust the pallet so that it is level with the adjacent surface, e.g. floor of the equipment room. 2. Cover the gap between the pallet and floor with a metal sheet (5 to 10 cm) so that the rollers do not get caught in the gap. 3. Place a roller on the metal sheet and under the cabinet frame. 4. Place a thick roller under the cabinet at a position where there are no cross-planks in the pallet. 5. With the assistance of installation personnel, push the cabinet off the pallet. 6. As the cabinet moves forward, place more rollers underneath. Note Use thick-walled steel rods. Round steel bars, round wooden timbers or steel rollers enclosed in concrete are also suitable for the purpose. The diameter of the rods must be at least 6 cm. The rods must be at least 20% longer than the cabinet.

To ensure long-term reliable operation of the equipment, suitable measures must be taken to prevent the ingress of dirt and dust. PVS 600Series 96 Operating Instructions, 08/2014, A5E03467293-003 Application planning 5.4 Site of installation 5.4.2 Requirements of electrical operating areas In addition to the environmental conditions for operation and the general requirements of sites of installation, electrical operating areas must also comply with further special requirements. The SINVERT inverter must be installed in a locked electrical operating area. DIN VDE 0100-200 defines a locked electrical operating area as a "room or space which is used exclusively for the operation of electrical equipment and which is kept locked". The lock may be opened only by authorized persons. Access is restricted to persons with appropriate electrical qualification. Compliance with the requirements of DIN VDE 0100-731 (Erection of power installations with rated voltages below 1000 V - Electrical locations and locked electrical locations) is particularly important. A number of key requirements are listed in brief below. For a detailed description of all requirements, please refer to the standards DIN VDE 0100-200, DIN VDE 0100-729 and DIN VDE 0100-731. These requirements must be met in every case. WARNING Danger of life from unauthorized access to electrical operating areas! If the requirements pertaining to locked electrical operating areas are not fulfilled, unauthorized persons might gain access to the inverter. Lack of knowledge in the safe handling of electrical installations by such persons could result in death, serious injury and substantial property damage. Barriers and labeling DIN VDE 0100-731 stipulates that electrical and locked electrical operating areas must be segregated from other areas by barriers of at least 1800 mm in height. Where the barriers are formed by grating, the maximum permissible mesh size is 40 mm. An adequate number of warning notices must be displayed at access points.

This means that if an error occurs in one inverter subunit, the other inverter subunits can remain in operation. Procedure 1. Turn the key-operated switch in the AC cabinet door of the inverter subunit to be switched off to the position "1-Lock". - The complete inverter shuts down and switches on again after 30 s in a controlled fashion, apart from the inverter subunits on which the key-operated switch is in the "1Lock" position. These inverter subunits are now decommissioned. 2. Wait until the green indicator light (operation state indicator) in the control cabinet door of the inverter subunit flashes slowly (operating state "IDLE"). WARNING Hazardous voltages in the switched-off inverter subunit The switched-off inverter subunit and the supply lines of the DC and AC inputs are still live. Results The green "READY" indicator light in the control cabinet door does not light up. The inverter subunit is locked but the supply lines are still live. The remainder of the inverter is still in operation. WARNING Hazardous voltages on the supply lines The supply lines of the DC and AC inputs are live. 8.4.2 Decommissioning the entire inverter In order to work on a SINVERT PVS inverter, the whole inverter unit must be isolated. This means that all inverter subunits must be decommissioned. PVS 600Series 134 Operating Instructions, 08/2014, A5E03467293-003 Commissioning 8.4 Decommissioning the inverter Procedure 1. Turn the key-operated switch in the AC cabinet door on all inverter subunits to the position "1-Lock". - After the first subunit is switched off, the complete inverter shuts down and attempts to switch on again after 30 s in a controlled fashion, apart from the inverter subunits on which the key-operated switch is already in the "1-Lock" position. - Therefore, all inverter subunits should be switched off rapidly because the inverter will try to switch on the remaining subunits again. 2. After all inverter subunits have shut down, wait until the green indicator light (operation state indicator) in the control cabinet door of each inverter subunit flashes slowly (operating state "IDLE"). 3. Open the cabinet doors. WARNING Hazardous voltages in the inverter cabinet The inverter is live. 4. Set the circuit breaker in the AC connection section to "0". 5. Switch off the auxiliary power supply. 6. Switch off the DC voltage (PV array). 7. Use a measuring device to check there is no voltage at the DC and AC inputs. Results The green "READY" indicator light in the control cabinet door does not light up. The inverter is locked and the cabinet is isolated. WARNING Hazardous voltages on the supply lines The supply lines of the DC and AC inputs are live.
