Wiring
When
using crimp terminals, refer to the
terminal clearances shown
below.

M5 (35 A, 45 A)
• 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 conditions
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 damaged.
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
.
