Precautions

Refer to page NO TAG for general precautions.

Installation

PCB Terminal-equipped Relays weigh approximately 140 g. Be

sure that the PCB is strong enough to support them. We recom-

mend 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

carefulnottopressthetestbuttonbymistakebecausethecontacts

will go ON if the test button is pressed.

Be sure to use the test button for test purposes only.

ThetestbuttonisusedforRelaycircuittests,suchasacircuitconti-

nuity test. Do not attempt to switch the load with the test button.

Minute 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 minute 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.

TheG7Jisnotofenclosedconstruction.Therefore,donotwashthe

G7J with water or any detergent.

Connecting

Allow suitable slack on leads when wiring, and do not subject the

Tightening torque: 0.98 N Sm

DonotimposeexcessiveexternalforceontheG7Jinthehorizontal

or vertical directions when inserting the G7J to the Faston recep-

tacle or pulling the G7J out from the Faston receptacle. Do not at-

tempt to insert or pull out more than one G7J Unit together.

Do not solder the tab terminals.
