ABSTRACT:
An electrophotographic copier apparatus having a plurality of 115 VAC single phase components which are connected in a balanced-load configuration to the two 115 VAC in-phase circuits of a 230 VAC power input plug. This plug is usable with a 230 VAC wall socket. When the copier is to be used in a location having only a 115 VAC wall socket, a passive electrical adapter connector is interposed between the copier's 230 VAC input plug and the 115 VAC wall socket. The adapter presents two in-phase 115 VAC circuits to the 230 VAC input plug. This adapter connector is stored within the copier's housing, such that the copier is readily usable with either an industry-standard 230 VAC or an industry-standard 115 VAC environment.
