This video describes that the aircraft can be supplied by a Ground Power Unit (GPU) connected to the external power receptacle located forward of the nose landing gear well. A ground External Power connector enables all bus bars to be supplied. External power characteristics are 115/200 volts, three phase, 400 Hz 90 kVA minimum. If the external power parameters are correct, the indicator lights on the external power panel and the AVAIL light on the EXT PWR P/B SW come on. The power parameters are monitored by the Ground and Auxiliary Power Control Unit (GAPCU) which activates the indicator lights. With such indications the ground cart can supply the aircraft network.
When the EXT PWR P/B SW is pushed, the ON blue legend illuminates and the GAPCU closes the External Power Contactor (EPC) to supply the aircraft electrical network. The Bus Tie Contactors (BTCs) 1 and 2 close if no engine driven generator is on line. The blue ON light, in the EXT PWR P/BSW, indicates that the EPC is closed.
