Otherwise, an electric shock may result. Do not apply overvoltage to the input terminals. Otherwise, the Unit may malfunction or burn. ## **Relay Models** Do not connect the Unit to loads exceeding the rated switching power (switching voltage or current). Otherwise, faulty insulation, contact weld, or faulty contact of Relays, or damage to Relays may result, or the Relays may malfunction or burn. The life of Relays varies with the switching condition. Test the Relays under the actual operating conditions before using the Relays within the permissible switching frequency. The use of deteriorated Relays may result in the faulty insulation of the Relays or cause the Relays to burn. Do not use the Unit in locations with inflammable gas. Otherwise, a fire or explosion due to the heat of the Relays or sparks from the Relays may result when they are switched. ## **Relays Mounted** G6B-4@@ND standard: G6B-1114P-FD-US-P6B G6B-4@@ND long life: G6B-1174P-FD G6B-4@@ND high reliability: G6B-1184P-US Replacement is not possible for G6B-48BND. ## **Wiring** Be sure to connect the input terminals with the correct polarity. ## **Coil Voltage** Be sure not to impose voltage exceeding the permissible voltage on the coil continuously. Do not use the relays when other inductive loads are connected in parallel with the coil input or when there are surges during power supply because the built-in diodes used to absorb surge may be destroyed. ## **Do Not Use the Following Circuit** ## ■ **Correct Use** ## **Mounting** Heat generated by the relays must be considered when gang-mounting. Space must be provided between the relays or other methods must be taken to maintain the relays’ ambient temperature at 55 °C or lower. ## **Replacement of Relays** ## **G6B-4** @@ **ND** Use the P6B-Y1 Removal Tool as shown in the following diagram. |Inductive load|G6B Coil|Coil surge current
absorption diode| |---|---|---| ## **Handling** Do not drop, shock, or vibrate the Unit excessively. Otherwise, damage to the Unit may result or the Unit may malfunction. Make sure that all the Relays are properly mounted before use. ## **Screw Tightening Torque** Tighten each terminal screw to a torque of 0.78 to 1.18N·m. Tighten each mounting screw to a torque of 0.59 to 0.98 N·m. ## **Installation Environment** Do not install the Unit in the following locations. Otherwise, damage to the Unit may result or the Unit may malfunction. Locations with direct sunlight. Be sure to turn OFF the power to the Unit before replacing a Relay. Relays must be inserted straight onto the socket connector pins to ensure proper connection. G6B-48BND models (high reliability) are connected directly to boards to increase reliability and the relays are thus not replaceable. If relay replacement is necessary, use the P6BF-4BND Terminal Sockets together with the G6B-1184P Mini Relays. P6BF-4BND Terminal Sockets are equipped with relay replacement sockets. Do not mount Relays that are different to one another in voltage. Locations with an ambient temperature range not within 0°C to 55°C. Locations with rapid temperature changes resulting in condensation or locations with relative humidity ranges not within 10% to 90%. Locations with corrosive or inflammable gas. Locations with excessive dust, salinity, or metal powder. Locations with vibration or shock affecting the Unit. Locations with water, oil, or chemical sprayed on the Unit. ## **Disassembly, Repair, and Modification** Do not disassemble, repair, or modify the Unit. Otherwise, an electric shock may result or the Unit may malfunction. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
