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 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 carefulnotto pressthetest buttonbymistakebecausethe contacts will go ON if the test button is pressed.

Be sure to use the test button for test purposes only. ThetestbuttonisusedforRelaycircuittests,suchasacircuitcontinuity 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, transformer, solenoid, lamp, and heater loads. Do not use the G7J for switching minute loads, such as signals. Use a Relay with a bifurcated 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 andthe G7J. As a result, the G7J may malfunction.

TheG7J isnotofenclosedconstruction.Therefore, donot washthe G7J with water or any detergent.

Connecting

Refertothefollowingdiagramwhen connecting a wirewitha screw terminal to the G7J.

M3.5

Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force.

Tightening torque: 0.98 NSm Donot imposeexcessiveexternalforceonthe G7Jinthehorizontal

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.
