G3PB Common
Wiring
When using crimp terminals, refer to the terminal clearances shown
below.
Output Terminals
Be sure that all lead wires are thick enough according to the
current.
Output terminals T1, T2, and T3 are charged regardless of
whether the Unit is a 2- or 3-element model that is turned on or
off. Do not touch these terminals, otherwise an electric shock
may be received.
To isolate the Unit from the power supply, install an appropriate
circuit breaker between the power supply and Unit.
Be sure to turn off the power supply before wiring the Unit.
Terminal L2 and terminal T2 of the 2-element model are
internally short-circuited to each other. Therefore, connect
terminal L2 to the ground terminal side 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, for the prevention of electric shock accidents and
ground faults.
Tightening Torque
Refer to the following and be sure to tighten each screw of the Unit to
the specified torque in order to prevent the Unit from malfunctioning.

Operating Conditions
Do not apply current exceeding the rated current otherwise, the
temperature of the G3PB may rise excessively.
Be sure to prevent the ambient temperature rising due to the heat
radiation of the G3PB. If the G3PB is mounted inside a panel,
install a fan so that the interior of the panel is fully ventilated.
Do not use the G3PB if heat dissipation fins have been bent as a
result of, for example, dropping the G3PB. If used in this state,
the G3PB may be damaged due to the decreased heat
dissipation capacity.
Only use the G3PB with loads that are within the rated values.
Using the G3PB with loads outside the rated values may result in
malfunction, damage, or burning.
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.
Keep wiring separate from high-voltage power lines and use
wires of an appropriate length, otherwise malfunction and
damage may result due to induction.
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.

Operating and Storage Environments

1. Operating Ambient Temperature
The rated value for the ambient operating temperature of the G3PB
is for when there is no built-up heat. For this reason, under condi-
tions where heat dissipation is not good due to poor ventilation, and
where heat may build up easily, the actual temperature of the G3PB
may exceed the rated value resulting in malfunction on burning.
When using the G3PB, design the system to allow heat dissipation
sufficient to stay below the Load Current vs. Ambient T emperature
characteristic curve. Note also that the ambient temperature of the
G3PB may increase as a result of environmental conditions (e.g.,
climate, air-conditioning) and operating conditions (e.g., mounting
in an airtight panel).
2. Operating and Storage Locations
Do not use or store the G3PB in the following locations. Doing so
may result in damage, malfunction, or deterioration of performance
characteristics.
Do not use or store in locations subject to direct sunlight.
Do not use in locations subject to ambient temperatures outside
the range –20 to 60 C.
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 changes in temperature.
Do not store in locations subject to ambient temperatures
outside the range –30 to 70 C.
Do not use or store in locations subject to corrosive or flammable
gases.
Do not use or store in locations subject to dust (especially iron
dust) or salts.
Do not use or store in locations subject to shock or vibration.
Do not use or store in locations subject to exposure to water, oil,
or chemicals.
3. Transportation
When transporting the G3PB, observe the following points. Not do-
ing so may result in damage, malfunction, or deterioration of perfor-
mance characteristics.
Do not drop the G3PB or subject it to severe vibrations or shock.
Do not transport the product if it is wet.
4. Vibration and Shock
Do not subject the SSR to excessive vibration or shock. Otherwise
the SSR may malfunction and internal components may be dam-
aged.
To prevent the SSR from abnormal vibration, do not install the G3PB
in locations or by means that will subject it to the vibrations from oth-
er devices, such as motors.
5. Solvents
Do not allow the G3PB to come in contact with solvents such as thin-
ners or gasoline. Doing so will dissolve the markings on the SSR.
6. Oil
Do not allow the G3PB terminal cover to come in contact with oil.
Doing so will cause the cover to crack and become cloudy.
