Installation

WARNING

Hazard due to electric shock

Before installation or maintenance work can begin, the system's main switch must be

switched off and measures taken to prevent it being switched on again. If this instruction is

not observed, touching live parts can result in death or serious injury.

5.1

Line-side connection

The SITOP PSU300S power supply is designed for connection to a 3-phase AC line supply

(TN or TT system according to VDE 0100 T 300 / IEC 364-3) with a rated voltage of

3-phase 400 - 500 VAC, 50 - 60 Hz.

Figure 5-1 Line connection (example: 6EP1436-2BA10)

The line supply is connected using terminal L1, L2, L3 and PE (see Figure Line connection

(example: 6EP1436-2BA10) (Page 31)), and must be implemented according to IEC 60364

and EN 50178 . A protective device (miniature circuit-breaker or circuit-breaker) and a

disconnection unit for the power supply must be provided. A ground-fault circuit interrupter is

not permissible against indirect contact as the only protective measure. This is true for the

complete line supply protected by the ground-fault circuit interrupter.

SITOP PSU300S

Manual, 12.2016, C98130-A7587-A1-7-7629 33

5.2

Output-side connection

At its output, the SITOP PSU300S power supply provides an isolated (= non-grounded)

SELV output voltage (Safety Extra Low Voltage). The output of the power supply is no-load,

overload, and short-circuit proof. If an overload occurs, the electronic current limiting function

limits the output current to a maximum value (refer to Chapter Technical data (Page 35)).

Figure 5-2 Connection of the output voltage (example: 6EP1436-2BA10)

The output voltage is connected via the + and - terminals at the output of the power supply

(see Figure Connection of the output voltage (example: 6EP1436-2BA10) (Page 33)).

Ensure that the output cables are dimensioned correctly for the maximum output current rms

value and fused accordingly.

Note

If the safety concept of the plant or system specifies that the DC output circuit should be

grounded (PELV), then it is permissible that the output voltage of the SITOP power supply is

ground

ed. In this case, ideally, the grounding at the output should be directly connected from

terminal "

-" of the power supply to a suitable connection point of the protective conductor

system (PE) of the plant or system.

Figure 6-6 Output characteristic 6EP1437-2BA20

The device supplies a constant output voltage until the current limit is reached. In the event

of an overload, the output current and the output voltage are reduced.

For 6EP1436-2BA10 and 6EP1437-2BA20, the following applies: When the output voltage

falls below approx. 10 V, the device switches off, and initiates an automatic restart. This

response is repeated as long as the overload condition is present.

9.1

Parallel connection to increase the power rating

To increase the power rating, power supplies of the same type can be directly connected in

parallel.

The following must be observed:

● The cables connected to each power supply at terminals "+" and "-" must have identical

lengths and the same cable cross-sections (or the same impedance) up to a common

external connection point (terminal strip) if possible.

● The power supplies connected in parallel must be switched on simultaneously with a

common switch in the line feeder cable (e.g. with the main switch available in control

cabinets).

● The output voltages measured in no-load operation for the power supplies that are not yet

connected in parallel should not deviate more than a maximum of 50 mV. This usually

corresponds to the factory setting. If the output voltage is changed, you should connect

the "-" terminals and then, in no-load operation, measure the voltage difference between

the "+" terminals that have not yet been connected. The voltage difference should not

exceed 50 mV.

NOTICE

Protective circuit for the parallel connection of more than two power supplies

When connecting more than two power supplies in parallel, additional measures must be

taken to prevent high backward feeding currents in the event of a secondary device

fault. For this purpose, a suitable protective circuit (e.g. decoupling diode or

DC-conform circuit breaker) must be installed between each "+" terminal of the power

supply and

the common connection point.

9.2

Parallel connection for redundancy

Connecting several 24 V power supplies in parallel for redundancy purposes is required if

especially high demands are placed regarding the availability of a reliable 24 V power

supply.

Using the SITOP PSE202U redundancy module, two power supplies of the same type up to

20 A can be decoupled (Figure 9-2 Redundant configuration with two power supplies and

SITOP PSE202U redundancy module (Page 55)). When one of the devices fails, then the

other automatically takes over the power supply. If one of the power supplies fails, then this

is signaled using an LED on the redundancy module as well as an isolated relay contact.

For higher output current, each power supply must be connected to a redundancy module

(Figure 9-3 Redundant configuration with two power supplies and two SITOP PSE202U

redundancy modules (Page 55)). When dimensioning the system, it must be ensured that

n+1 redundant connected power supplies can handle the total power requirement of the

remaining n power supplies.

Note

For a high reliability of the su

pply, it is recommended that the redundant switched power

supplies are fused separately on the line

-side and, if possible, be connected to different

power supply networks.

Series connection for increased voltage

To achieve an output voltage of 48 V DC, two 24 V SITOP power supplies of the same type

can be connected in series.

Depending on the grounding point of the secondary output voltages, voltages of +48 V,

±24 V or -48 V can be realized.

WARNING

SELV is not guaranteed in the case of a fault

When connecting two power supplies in series, the continuous, permissible SELV voltage

of a maximum of 60 VDC according to EN 60950-1 cannot be guaranteed in the case of a

fault.

9.4 Overload protection in the 24 V output circuit

SITOP PSU300S

58 Manual, 12.2016, C98130-A7587-A1-7-7629

9.4

Overload protection in the 24 V output circuit

If an overload occurs, the electronic current limiting function of the 24 V power supply limits

the output current to a maximum value (see Section Technical data (Page 35)). The output

cables are protected against a thermal overload if they are dimensioned corresponding to

the maximum rms output current, or protected using additional components (for example,

miniature circuit breaker, fuses).

However, a load circuit that fails as a result of overload, for instance, should frequently be

reliably and quickly identified and specifically switched off before the power supply goes into

current-limiting mode (in current-limiting mode, the supply voltage would also be reduced for

all of the remaining 24 V loads).

The SITOP PSE200U selectivity module with 4 outputs (versions with adjustable output

current range for each output from 0.5 - 3 A and 3 - 10 A) is available for this purpose; this

monitors the 24 V branches for overload and short circuit (Figure 9-5 Electronic protection of

24 V loads using the SITOP PSE200U selectivity module (Page 58)). Brief current peaks,

e.g. as a result of a high inrush current, are permitted, and branches with a longer overload

are switched into a no-current condition. This is also ensured for cables in a high-ohmic

condition and for short circuits that slowly develop over time.

When an output fails, the fault is signaled using a group signal contact or as a single channel

signal, and the branch of the module involved is displayed using an LED.

For variants with single-channel signaling, function blocks for evaluation purposes are

available for SIMATIC S7-1200/1500/300/400, for STEP 7 Classic and TIA Portal at no

charge.

9.5 Protection against short-time voltage dips

SITOP PSU300S

Manual, 12.2016, C98130-A7587-A1-7-7629 59

9.5

Protection against short-time voltage dips

For a drop in the line-side supply voltage, the 24 V power supply still maintains the output

voltage for a short time in the millisecond range (see Chapter Technical data (Page 35)).

For line supplies that manifest frequent brief voltage dips, in order to increase the power

supply reliability, it may make sense to increase the line buffering time in the device using an

additional SITOP PSE201U buffer module.

The SITOP PSE201U buffer module, based on electrolytic capacitors, is connected in

parallel to the power supply output (Figure 9-6 Buffering brief power failures using the SITOP

PSE201U buffer module (Page 59)). The buffer time is 200 ms at 40 A up to 1.6 s for a load

current of 5 A. This time can be increased a multiple number of times by connecting buffer

modules in parallel; the maximum buffer time is 10 s.

9.6

Protecting against longer power failures

Sudden and longer failures of the line supply voltage can result in undefined states and

significant danger as a result of the associated failure of the plant or system control. The

SITOP power supply product portfolio includes various DC-UPS solutions to prevent the

failure of the 24 V power supply voltage.

Power supply failures up into the minutes range can be buffered using the maintenance-free

SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-7 24 V buffering to allow

the saving of process data and controlled shutdown of PCs (Page 60)).

Figure 9-7 24 V buffering to allow the saving of process data and controlled shutdown of PCs

Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply

integrated into PC-based automation solutions. This supports further processing of the status

signals and safely running down the PC.
