Safety Precautions
Refer to Safety Precautions for All Solid State Relays.
CAUTION
The G3PF 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 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 become extremely hot.
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 electrical shock may occasionally occur.
Always turn OFF the power supply before
performing wiring. Also, always attach the cover
terminal.
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.
(1) Operating and Storage Environments
Do not use or store the G3PF in the following locations. Doing
so may result in damage, malfunction, or deterioration of
performance characteristics.
1. Locations subject to corrosive or flammable gases.
2. Do not store in locations subject to ambient storage
temperatures outside the range −30 to 70°C.
3. Do not use in locations subject to ambient operating
temperatures outside the range −20 to 60°C.
4. Do not use in locations subject to relative humidity outside
the range 25% to 85%.
5. Locations subject to high temperature or high humidity.
6. Locations subject to condensation as the result of rapid
changes in temperature.
7. Locations subject to exposure to water, oil, or chemicals.
8. Locations subject to dust (especially iron dust) or salts.
9. Locations subject to rainwater or water splashes.
10.Locations subject to direct sunlight.
11.Locations subject to shock or vibration.
(2) Transport
Do not transport the G3PF under the following conditions.
Doing so may result in damage, malfunction, or deterioration
of performance characteristics.
1. Conditions in which the G3PF may be subject to water or
oil splashes.
2. Conditions in which the G3PF may be subject to high
temperature or high humidity.

3. Conditions in which the G3PF may be subject to
condensation as the result of rapid changes in
temperature.
4. Conditions in which the G3PF may be dropped or subject
to excessive vibration or shock.
5. Conditions in which the G3PF is not packaged.
(3) Mounting
1. Do not use the G3PF 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.
2. Do not block the movement of the air surrounding the
SSR or heat sink.
Abnormal heating of the SSR may result in shorting
failures of the output elements or burn damage.
3. Make sure that there is no excess ambient temperature
rise due to the heat generation of the G3PF. If the G3PF
is mounted inside a panel, install a fan so that the interior
of the panel is fully ventilated. Otherwise, shorting failures
of the output elements or burn damage may result.
4. Make sure the DIN track is securely mounted. Otherwise,
the G3PF may fall.
5. Do not handle the G3PF with oily or dusty (especially iron
dust) hands. Doing so may result in malfunction.
6. Mount the G3PF in the specified direction (on a vertical or
horizontal surface). Otherwise excessive heat generated
by the G3PF may cause short-circuit failures of the output
elements or burn damage.

7. When mounting the G3PF to a control panel or other
fixture with screws, be sure to tighten the screws to a
torque of 0.98 to 1.47 N·m. A lower level of tightening
torque may cause the G3PF to fall.
8. Do not drop the G3PF or subject it to excessive vibration
or shock. Doing so may result in damage, malfunction, or
deterioration of performance characteristics.
(4) Wiring
1. Use wires that are thick enough for the load current.
Otherwise, excessive heat generated by the wire may
cause burning.
Tightening torque M2: 0.22 to 0.28 N·m
M3: 0.4 to 0.56 N·m
M5: 1.57 to 2.35 N·m
Control connector mounting torque (detachable
terminal)
0.25 to 0.3 N·m
2. 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.
3. Use wires that are suited to the load current and voltage.
Otherwise, excessive heat generated by the wires may
cause burning, or the outer covering of the wire may melt,
resulting in electrical shock or ground fault.
4. Use a crimp terminal size that is suited to the diameter of
the wire. Otherwise, it may result in burning, or the outer
covering of the wire may melt, resulting in electrical shock
or ground fault.
