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.
