Connecting Installation Refer to the following diagram when connecting a wire with a screw terminal to the G7J. 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. Be sure to use the test button for test purposes only. The test button is used for Relay circuit tests, such as a circuit continuity 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 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. 7.6 4.5 M3.5 Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force. Tightening torque: 0.98 N S m 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.

G7J G7J Operating Coil Internal Connections of Coils DC coil A2 A1 AC coil A2 A1 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. Be sure to perform a trial operation with the G7J and the triac before applying them to actual use. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
