Notes: 1. Create a sequence circuit that turns off the magnetic contactor when abnormal overheating occurs. 2. G3 and G4 terminals are thermal sensor. G3-G4 opens when the regenerative option overheats abnormally. 3. The wire size shows wiring specification of the connector. Refer to "Wires, Molded-Case Circuit Breakers and Magnetic Contactors" in this catalog for examples of wire size selection.
