Safety Precautions
Refer to Safety Precautions for All Relays.
■ Correct Use
Installation
PCB Terminal-equipped Relays weigh approximately 140 g. Be sure that
the PCB is strong enough to support them. We recommend dual-side
through-hole PCBs to reduce solder cracking from heat stress.
Mount the G7J with its test button facing downwards. The Relay may
malfunction due to shock if the test button faces upwards. Be careful
not to press the test button by mistake because the contacts will go
ON if the test button is pressed.
If the normal mounting direction is not used, carbides or powder from
contact abrasion that results from load switching will accumulate
inside the Relay. If the Relay is used past its endurance in this state,
insulation failure between circuits of different polarity or Relay burn-
ing may occur.
Be sure to use the test button for test purposes only.
The test button is used for Relay circuit tests, such as a circuit conti-
nuity test. Do not attempt to switch the load with the test button.
If a voltage is applied to the coil, the test button will retract in an ON
state (i.e., an excited state).
Micro Loads
The G7J is used for switching power loads, such as motor, trans-
former, solenoid, lamp, and heater loads. Do not use the G7J for
switching minute loads, such as signals. Use a Relay with a bifur-
cated contact construction for switching micro loads, in which case,
however, only SPST-NO or SPST-NC output is obtained.
Soldering PCB Terminals
Be sure to solder the PCB terminals manually only. In the case of
automatic soldering, some flux may stick to the test button and the
G7J. As a result, the G7J may malfunction.
The G7J is not of enclosed construction. Therefore, do not wash the
G7J with water or any detergent.
Connecting
Refer to the following diagram when connecting a wire with a screw
terminal to the G7J.
Allow suitable slack on leads when wiring, and do not subject the ter-
minals to excessive force.
Tighter the terminal screws with torque 0.78 to 1.18 N·m. Loose
screws result in disconnection of lead wire, malfunction or fire.

Faston Tabs
Do not impose excessive external force on the G7J in the horizontal
or vertical directions when inserting the G7J to the Faston receptacle
or pulling the G7J out from the Faston receptacle. Do not attempt to
insert or pull out more than one G7J Unit together.
Do not solder the tab terminals.
Note: Numbers in parentheses are for air feed use.
Operating Coil
Internal Connections of Coils
If a transistor drives the G7J, check the leakage current, and connect
a bleeder resistor if necessary.
The AC coil is provided with a built-in full-wave rectifier. If a triac,
such as an SSR, drives the G7J, the G7J may not release. Use the
Power MOS FET Relay in this case.
