Precautions
!WARNING
Do not touch the relay while power is supplied or immediately after
G3TC is turned OFF. Doing so may result in burns.
!WARNING
9. For a DC inductive load, a diode should be connected in parallel
with the load to absorb the counter electromotive force of the
load.
10.For an I/O mounting rack that is installed horizontally, use the
G3TC with loads that are within the following conditions.
G3TC-OAC5, -OAC5A, -OAC15, -OAC15A, -OAC24, -OAC24A
Do not touch the load terminal of the G3TC immediately after the
power is turned OFF, otherwise an electric shock may be received
due to the residual charge of the built-in C/R circuit.
4
!WARNING
3
Be sure to turn OFF the power supply to the G3TC before wiring,
otherwise an electric shock may result.
Ensure that a short-circuit current does not flow on the load side of
the SSR, otherwise the G3TC may be damaged.

■ General Precautions
1. Do not apply excessive voltage or current to the input or output
circuit of the G3TC. Doing so may result in malfunction or burning.
2. Do not connect the input and output circuits incorrectly. Doing so
may result in malfunction or burning.
3. Do not obstruct the flow of air around the G3TC. Abnormal heating of the G3TC may result in short-circuiting of output elements
and burning.
■ Correct Use
Before Actual Operation
1. In actual operation, the G3TC may cause accidents that were
unforeseeable at the theoretical stage. Therefore, it is necessary
to test the G3TC under a variety of conditions that are possible.
As for the characteristics of the G3TC, it is necessary to consider
the differences between G3TC models.
2. The ratings in this datasheet are for testing in a temperature
range of 15 to 30°C, a relative humidity range of 25% to 85%, and
an atmospheric pressure range of 88 to 106kPa. When testing
operation, it is necessary to confirm correct operation not only
with the actual load that will be used, but also at the same ambient conditions as for actual operation.
3. The input circuitry does not incorporate a circuit protecting the
SSR from being damaged due to a reversed connection. Make
sure that the polarity is correct when connecting the input lines.
4. Only use the G3TC with loads that are within the rated values.
Using the G3TC with loads outside the rated values may result in
malfunction, damage, or burning.
5. Use a power supply within the rated frequency range. Using a
power supply outside the rated frequency range may result in
malfunction, damage, or burning.
6. No over-voltage absorption element is built in. Therefore, if the
G3TC is connected to an inductive load, be sure to connect an
over-voltage absorption element.
7. As protection against accidents due to short-circuiting, be sure to
install protective devices, such as fuses on the power supply side.
8. Keep wiring separate from high-voltage power lines and use wires
of an appropriate length, otherwise malfunction and damage may
result due to induction.

Load current (A)
At OMRON, we are constantly working to improve the quality and
reliability of our products. SSRs, however, use semiconductors,
which are prone to malfunction. Be sure to use SSRs within their
rated value. Use the SSR only in systems that are designed with
redundancies, flame protection, counter measures to prevent operation errors, and other countermeasures to prevent accidents involving human life or fires.

■ Operating and Storage
Environments
Transportation
When transporting the G3TC, observe the following points. Not doing
so may result in damage, malfunction, or deterioration of performance characteristics.
Operating Ambient Temperature
The rated value for the ambient operating temperature of the G3TC
is for when there is no built-up heat. For this, reason, under conditions where heat dissipation is not good due to poor ventilation, and
where heat may build up easily, the actual temperature of the G3TC
may exceed the rated value resulting in malfunction or burning.
When using the G3TC, design the system to allow heat dissipation
sufficient to stay below the Load Current vs. Ambient Temperature
characteristic curve. Note also that the ambient temperature of the
G3TC may increase as a result of environmental conditions (e.g., climate, air-conditioning) and operating conditions (e.g., mounting in an
airtight panel).
1. Do not drop the G3TC or subject it to severe vibrations or shock.
2. Do not transport the product if it is wet.
Vibration and Shock
Do not subject the SSR to excessive vibration or shock. Otherwise
the SSR may malfunction and internal components may be damaged.
Operating and Storage Locations
Do not use or store the G3TC in the following locations. Doing so
may result in damage, malfunction, or deterioration of performance
characteristics.
1. Do not use or store in locations subject to direct sunlight.
2. Do not use in locations subject to ambient temperatures outside
the range -30° to 80°C.
3. Do not use in locations subject to relative humidity outside the
range 45% to 85% or locations subject to condensation as the
result of severe change in temperature.
4. Do not store in locations subject to ambient temperatures outside
the range -30° to 100°C.
5. Do not use or store in locations subject to corrosive or flammable
gases.
6. Do not use or store in locations subject to dust (especially iron
dust) or salts.
7. Do not use or store in locations subject to shock or vibration.
8. Do not use or store in locations subject to exposure to water, oil,
or chemicals.
