3.Tighten the connector housing to ensure a tight fit between the power cord and the connector body. This will prevent the cable from pulling out of the terminal block and also prevent moisture from entering the control box.

It is recommended that the power being supplied to the control box ALWAYS be connected to a circuit breaker or a quick disconnect switch.This safety feature allows for quick removal of power from the control box in the event of an emergency.

4.Connect the other end of the 3-phase input power cord to the voltage source. Remember to provide a means of disconnecting the power from the control box (circuit breaker or quick disconnect switch). Also make sure to provide a good earth ground to the control box.
