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.

• 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 natu-

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 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.
