Connect 3-wire Module Power

Connecting the power must be performed by a quali- fied electrician. The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.
