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., current­carrying parts) while the power is being supplied.

Cover must remain on relay at all times.

The G3PE may rupture if short-circuit current flows.
As protection against accidents due to short­circuiting, 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 built­in snubber circuit.

Minor burns may occasionally occur.
Do not touch the SSR or the heat sink while the power
is being supplied or immediately after the power
supply has been turned OFF. The SSR and heat sink
may become extremely hot.

Precautions for Safe Use

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
performance 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.

G3PE

Installation and Handling

• Do not block the movement of the air surrounding the G3PE or heat
sink. Abnormal heating of G3PE may result in shorting
of 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.

• Make sure the heat sink that comes with the G3PE Relay stays
attached to it.

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.

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.

G3PE

Precautions for Correct Use

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.

Terminals Screw terminal diameter Tightening torque

Input terminals M3.5 0.59 to 1.18 N·m

• 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.

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
naturally.
When close-mounting G3PE SSRs, check Load Current vs.

G3PE

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 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 mounting 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.

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

The rated current of the G3PE is measured at an ambient
temperature of 40°C.
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. 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.)
