Doing so may affect performance. • Use the power relay in a dry environment free from excessive dust, SO2, H2S, or organic gas. Refer to the diagram below when connecting a wire to the screw terminals on G7J. • Do not allow a voltage greater than the maximum allowable coil voltage to be applied continuously. • Do not use the relay outside of specified voltages and currents. • Do not allow the ambient operation temperature to exceed the specified limit. ■ Microloads The G7J is used for switching power loads. Do not use the G7J for switching minute loads, such as signals. ■ Installation Although there are not specific limits on the installation site, it should be as dry and dust-free as possible. PCB terminal-equipped relays weigh approximately 140 g. Be sure that the PCB is strong enough to support them. OMRON recommends dual-side through-hole PCBs to reduce solder cracking from heat stress. 7.6 (0.299) 8.8 (0.346) 7 (0.276) 4.5 (0.177) M3.5 Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force. Tighten the screw terminals to a torque of 0.78 to 1.18 N-m. ■ Quick-connect Terminals Do not impose excessive external force on the G7J in the horizontal or vertical directions when inserting the G7J to the quick-connect terminals or when removing the terminals from the G7J. Do not attempt to insert or pull out more than one terminal at a time. 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 actuate (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 burning 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 continuity 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). ■ 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 relay. As a result, the G7J may malfunction. ■ Cleaning PCB Terminals PCB terminals have semi-sealed construction which prevents flux from penetrating into the relay base housing due to capillary action. This type of relay cannot be immersed for cleaning. Do not wash with any water or detergent. General Purpose Relay G7J 327 ■ Coil Internal Circuit If a transistor drives the G7J, then check the leakage current and connect a bleeder resistor if necessary. AC operating coil DC operating coil A2 A1 A2 A1 As a rule, either a DC battery or a DC power supply with a maximum of 5% ripple must be used for the operating voltage for DC relays. Before using a rectified AC supply, confirm that the ripple is not greater than 5%. Ripple greater than this can lead to variations in the operating and reset voltages. As excessive ripple can generate pulses, the insertion of a smoothing capacitor is recommended as shown below. The G7J incorporates a bridge rectifier circuit in the AC coil versions that prevents contact chatter or dropout during a voltage drop. This circuit allows the relays to withstand, with no vibration or shock, voltage drops to the coil of up to 50% of the rated coil voltage for one second maximum. Smoothing capacitor If a triac, such as an SSR, drives the G7J, the G7J may not release. Use a Power MOS FET in this case. Relay Ripple E min. E max.
