Safety Precautions
Refer to Safety Precautions for All Solid State Relays.
!CAUTION
Minor electrical shock may occasionally occur.
Do not touch the G3PE terminal section (i.e., current-
carrying parts) while the power is being supplied.
Also, always attach the cover terminal.
The G3PE may rupture if short-circuit current flows.
As protection against accidents due to short-
circuiting, be sure to install protective devices, such
as fuses and no-fuse breakers, on the power supply
side.
Minor electrical shock may occasionally occur.
Do not touch the main circuit terminals on the SSR
immediately after the power supply has been turned
OFF. Shock may result due to the electrical charge
stored in the built-in snubber circuit.
Minor burns may occasionally occur.
Do not touch the SSR or the heatsink while the power
is being supplied or immediately after the power
supply has been turned OFF. The SSR and heatsink
become extremely hot.
OMRON constantly strives to improve quality and reliability.
SSRs, however, use semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible to
ensure safety if the SSRs are used outside the rated ranges.
Therefore, always use the SSRs within the ratings. When using an
SSR, always design the system to ensure safety and prevent human
accidents, fires, and social harm in the event of SSR failure. System
design must include measures such as system redundancy,
measures to prevent fires from spreading, and designs to prevent
malfunction.
Transport
Do not transport the G3PE under the following conditions.
Doing so may result in damage, malfunction, or deterioration of per-
formance characteristics.
•Conditions in which the G3PE may be subject to water.
•Conditions in which the G3PE may be subject to high temperature
or high humidity.
•Conditions in which the G3PE is not packaged.
Operating and Storage Environments
Do not use or store the G3PE in the following locations. Doing so
may result in damage, malfunction, or deterioration of performance
characteristics.
•Locations subject to rainwater or water splashes.
•Locations subject to exposure to water, oil, or chemicals.
•Locations subject to high temperature or high humidity.
•Do not store in locations subject to ambient storage temperatures
outside the range −30 to 100°C.
•Do not use in locations subject to relative humidity outside the
range 45% to 85%.
•Locations subject to corrosive gases.
•Locations subject to dust (especially iron dust) or salts.
•Locations subject to direct sunlight.
•Locations subject to shock or vibration.
Installation and Handling
•Do not block the movement of the air surrounding the G3PE or heat
sink. Abnormal heating of the G3PE may result in shorting failures
of the output elements or burn damage.
•Do not use the G3PE if the heat radiation fins have been bent by
being dropped. Doing so may result in malfunction due to a
reduction in the heat radiation performance.
•Do not handle the G3PE with oily or dusty (especially iron dust)
hands. Doing so may result in malfunction.
•Attach a heat sink or radiator when using an SSR. Not doing so
may result in malfunction due to a reduction in the heat radiation
performance.
Installation and Mounting
•Mount the G3PE in the specified direction. Otherwise excessive
heat generated by the G3PE may cause short-circuit failures of the
output elements or burn damage.
•Make sure that there is no excess ambient temperature rise due to
the heat generation of the G3PE. If the G3PE is mounted inside a
panel, install a fan so that the interior of the panel is fully ventilated.
•Make sure the DIN track is securely mounted. Otherwise, the
G3PE may fall.
•When mounting the heat sink, do not allow any foreign matter
between the heat sink and the mounting surface. Foreign matter
may cause malfunction due to a reduction in the heat radiation
performance.
•If the G3PE is mounted directly in a control panel, use aluminum,
steel plating, or similar material with a low heat resistance as a
substitute for a heat sink. Using the G3PE mounted in wood or
other material with a high heat resistance may result in fire or
burning due to heat generated by the G3PE.
Installation and Wiring
•Use wires that are suited to the load current. Otherwise, excessive
heat generated by the wires may cause burning.
•Do not use wires with a damaged outer covering.
Otherwise, it may result in electric shock or ground leakage.
•Do not wire any wiring in the same duct or conduit as power or
high-tension lines. Otherwise, inductive noise may damage the
G3PE or cause it to malfunction.
•When tightening terminal screws, prevent any non-conducting
material from becoming caught between the screws and the
tightening surface. Otherwise, excessive heat generated by the
terminal may cause burning.
•Do not use the G3PE with loose terminal screws. Otherwise,
excessive heat generated by the wire may cause burning.
•For the G3PE models with a carry current of 35 A or larger, use M5
crimp terminals that are an appropriate size for the diameter of the
wire.
•Always turn OFF the power supply before performing wiring. Not
doing so may cause electrical shock.
Installation and Usage
•Select a load within the rated values. Not doing so may result in
malfunction, failure, or burning.
•Select a power supply within the rated frequencies. Not doing so
may result in malfunction, failure, or burning.
•The G3PE provides a circuit to prevent photocoupler damage by
forcibly arcing the output element for surge voltages applied to the
load. The G3PE therefore cannot be used for motor loads. Doing
so may result in load motor malfunction.
Precautions for Safe Use
Single-phase Solid State Relays for Heaters G3PE 451
The SSR in operation may cause an unexpected accident.
Therefore it is necessary to test the SSR under the variety of
conditions that are possible.
As for the characteristics
of the SSR, it is
necessary to consider differences in characteristics between
individual SSRs.
The ratings in this catalog are tested values in a temperature range
between 15°C and 30°C, a relative humidity range between 25% and
85%, and an atmospheric pressure range between 86 and 106 kPa.
It
will be necessary
to provide the above conditions as well as the load
conditions if the user wants to confirm the ratings of specific SSRs.
Causes of Failure
•Do not drop the G3PE or subject it to abnormal vibration or shock
during transportation or mounting. Doing so may result in
deterioration of performance, malfunction, or failure.
•Tighten each terminal to the torque specified below. Improper
tightening may result in abnormal heat generation at the terminal,
which may cause burning.
•Do not supply overvoltage to the input circuits or output circuits.
Doing so may result in failure or burning.
•Do not use or store the G3PE in the following conditions. Doing so
may result in deterioration of performance.
•Locations subject to static electricity or noise
•Locations subject to strong electric or magnetic fields
•Locations subject to radioactivity
Mounting
•The G3PE is heavy. Firmly mount the DIN Track and secure both
ends with End Plates for DIN Track mounting models. When
mounting the G3PE directly to a panel, firmly secure it to the panel.
Screw diameter: M4
Tightening torque: 0.98 to 1.47 N·m
Note: Make sure that the load current is 50% of the rated load current
when the G3PE is mounted horizontally.
For details on close mounting, refer to the related information
under performance characteristics.
Mount the G3PE in a direction so that the markings read natu-
rally.
Wiring
•When using crimp terminals, refer to the terminal clearances
shown below.
•Make sure that all lead wires are thick enough for the current.
•For three-element and two-element models, the output terminal will
be charged even when the Relay is OFF. Touching the terminal
may result in electric shock. To isolate the Relay from the power
supply, install an appropriate circuit breaker between the power
supply and the Relay.
Always turn OFF the power supply before wiring the Unit.
•Terminal L2 and terminal T2 of a 2-element model are internally
connected to each other. Connect terminal L2 to the ground
terminal of the power supply.
If terminal L2 is connected to a terminal other than the ground
terminal, cover all the charged terminals, such as heater terminals,
to prevent electric shock and ground faults.
Fuses
•Use a quick-burning fuse on the output terminals to prevent
accidents due to short-circuiting. Use a fuse with equal or greater
performance than those given in the following table.

EMC Connection
Make EMC connections according to the following figure.
•Connect a capacitor to the load power supply.
•The input cable must be no longer than 3 m.
EMI
This is a Class A product (for industrial environments). In a domestic
environment, the G3PE may cause radio interference, in which case
the user may be required to take appropriate measures.
Noise and Surge Effects
If noise or an electrical surge occurs that exceeds the malfunction
withstand limit for the G3PE output circuit, the output will turn ON for
a maximum of one half cycle to absorb the noise or surge. Confirm
that turning the output ON for a half cycle will not cause a problem for
the device or system in which the G3PE is being used prior to actual
use. The G3PE malfunction withstand limit is shown below.
•Malfunction withstand limit (reference value): 500 V
Note: This value was measured under the following conditions.
Noise duration: 100 ns and 1 μs
Repetition period: 100 Hz
Noise application time: 3 min
Mounting Models with Externally Attached Heat Sinks
•Before attaching an external Heat Sink or Radiator to the Unit,
always apply silicone grease, such as Toshiba Silicone's YG6260
or Sinetsu Silicone's G746, to the mounting surface to enable
proper heat radiation.
•Tighten the screws to the following torque to secure the Unit and
external Heat Sink or Radiator to enable proper heat dissipation.
Tightening torque: 2.0 N·m
Mounting to Control Panel
The G3PE is heavy. Firmly mount the DIN track and secure both
ends with End Plates for DIN-track-mounting models. When mount-
ing the G3PE directly to a panel, firmly secure it to the panel.
If the panel is airtight, heat from the SSR will build up inside, which
may reduce the current carry ability of the SSR or adversely affect
other electrical devices. Be sure to install ventilation holes on the top
and bottom of the panel.

Objects Blocking Airflow
Ventilation Outside the Control Panel
Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly
to prevent it from clogging to ensure an efficient flow of air.
2. Do not locate any objects around the air inlet or air outlet,
otherwise the objects may obstruct the proper ventilation of
the control panel.
3. A heat exchanger, if used, should be located in front of the
G3PE to ensure the efficiency of the heat exchanger.
G3PE Ambient Temperature
15A and 25A models have ambient temperature of 40°C, while 35A
and 45A models have 25°C ambient Temperature. The G3PE uses a
semiconductor to switch the load. This causes the temperature inside
the control panel to increase due to heating resulting from the flow of
electrical current through the load. The G3PE reliability can be
increased by adding a ventilation fan to the control panel to dispel
this heat, thus lowering the ambient temperature of the G3PE.
(Arrhenius's law suggests that life expectancy is doubled by each
10°C reduction in ambient temperature.)
Example: For 10 G3PE SSRs with load currents of 15 A,
0.23 × 10 = 2.3
Thus, 3 fans would be required.
Note: 1. Size of fans: 92 mm × 92 mm, Air volume: 0.7 m3/min,
Ambient temperature of control panel: 30°C
2. If there are other instruments that generate heat in the
control panel in addition to SSRs, more ventilation will be re-
quired.
3. Ambient temperature: The temperature that will allow the
SSR to cool by convection or other means.
