■ Precautions for Safe Use
Operation and Storage Locations
• Do not use or store the SSR in the following locations. Doing so
Installation
• Do not drop the product or subject it to abnormal vibration or shock.
• Do not install the product if your hands are dirty with oil or metal
Installation and Handling
• The product is heavy. Firmly mount it on a DIN Track. Also securely
• Mount the product in the specified mounting direction. Abnormal
Installation and Wiring
• Make sure that all lead wires are appropriate for the load current.
• Do not use wires with a damaged sheath. Doing so may result in
• Do not wire power lines or high-tension lines along with the control
• Use wires of an appropriate length. Wires of improper length may
• Connect to the primary side (i.e., power supply side) of the G3JA
Always turn OFF the power supply if there is a possibility
that the terminals may be touched. Not doing so may
occasionally result in minor electric shock.
Firmly tighten the screws to the specified torque. If the
screws are not firmly tightened, minor fires may
occasionally occur. Refer to Specifications and
Accessories (Order Separately) for details.

internal circuit may occasionally result in minor electric
shock. Before touching the terminals, turn OFF the power
supply and make sure that the voltage has been
eliminated due to discharge.

• Select a power supply that is in the rated frequencies. Not doing so
■ Precautions for Correct Use
Altitude Derating
The rated current of the G3JA must be decreased at altitudes above
2,000 m because of decreased efficiency of the heat sink and fan
(G32J-CF64).
Warning Labels Included with Product
If voltage is applied to the main circuit power supply side of the
G3JA, there will be voltage in the terminals on the main circuit load
side even if the G3JA is OFF. Be sure to use the warning labels
included with the product to provide notification of this hazard on
locations such as the motor terminal box, G3JA, and control panel.
Main Circuit Cutoff at Error
Safety is further improved by turning OFF the contacts and other
lines on the main circuit power supply side of the G3JA as shown in
the following figure. For a wiring example, refer to Examples: Main
Circuit Fault Shutoff.
Standard Connection Diagram for Main Circuit Cutoff at Error
Connecting Varistors
The G3JA will be damaged by overvoltage if
high-energy surge voltage builds up in the AC
power supply that is used. If surge voltage is a
problem, connect three varistors with one on
each phase in the position shown in the following
figure. The following varistor is recommended.
Also, when you connect the varistor, always
install a fuse, breaker, or other protective device
on the power supply side of the varistor.
Limiting Resistor
The G3JA cannot use a limiting resistor.
Operation Start Signal
Do not apply an operation start signal during a soft stop. Doing so
will result in abnormal operation.
mounting, it is recommended to install
them with a gap of approximately 5 mm
between Units. (No gap is required for
Auxiliary Contact Units.)
If close mounting is used, also take into
account the increase in ambient
temperature due to heat dissipated by the
Units themselves. In particular, use fans for
sufficient ventilation with external air if the
Units are mounted inside a panel.
Doing so will result in abnormal heat radiation.
