    Wiring Conduit plugs are provided for 1in, 3/4 inch and ½ inch conduit fittings. If conduit fitting not fit 1in, 3/4in or 1/2in, an appropriate conduit reducer or adapter should be used. Caution: Do not enlarge the wiring compartment conduit openings as the wiring box enclosure will be damaged which will void the inverter warranty.
