TYPICAL ELECTRICAL DIAGRAMS

WARNING: Perform the wiring operation with the power source “OFF”. Make sure the voltage and current requirements are within the SWICHGAGE® ratings. Before wiring determine voltage and polarity for the application. Use the appropriate wire size. All connections should be made using a spade (forked) or ring terminals. For pigtail connections use wire nuts. Conduit is recommended to protect wires from damage.
