The case is not designed to be removed during normal handling and operation. Doing so may affect performance. Use the Power Relay in a dry environment free from excessive dust, SO2, H2S, or organic gas. Do not allow a voltage greater than the maximum allowable coil voltage to be applied continuously. Do not use the Power Relay outside of specified voltages and currents. Do not allow the ambient operating temperature to exceed the specified limit. Refer to the following diagram when connecting a wire with a screw terminal to the G7J. 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. 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. 7.6 8.8 7 4.5 M3.5 Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force. Tightening torque: 10 kgf $ cm (0.98 N $ m) Cleaning PCB Terminals PCB terminals have a flux protection construction which prevents flux from penetrating into the relay base housing, e.g., due to capillary action up the terminals when a relay is soldered onto the PCB. This type of relay cannot be immersed for cleaning. 5 G7J G7J Operating Coil Internal Connections of Coils DC coil A2 A1 AC coil 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. Smoothing capacitor + – Relay Ripple E min. E max. E mean DC fraction % of ripple = E max. – E min. x 100 E mean E max.: Max. ripple E min.: Min. ripple E mean: Mean DC value When driving a transistor, check the leakage current and connect a bleeder resistor if necessary. 6 G7J G7J 7
