R (1) If the fault continues:
R - do a check of the external power feeders (Ref. ASM 24-41/01) for a
R correct phase connection between:
R . terminal A of the external power receptacle (20XG) and terminal K
R of the EPC (3XG)
R . terminal B of the external power receptacle and terminal L of the
R EPC
R . terminal C of the external power receptacle and terminal M of the
R EPC.
R (a) If the feeders are not correct:
R - connect the feeders as necessary to get the correct phase
R sequence.
R (b) If the feeders are correct:
R - do a check of the Point-Of-Regulation (POR) sense wiring (Ref.
R ASM 24-41/01) for a correct phase connection between:
R . terminal J of the EPC (3XG) and pin B/15J of the GAPCU (phase
R A)
R . terminal H of the EPC and pin B/14J of the GAPCU (phase B)
R . terminal G of the EPC and pin B/13J of the GAPCU (phase C).
R 1 If the wiring is not correct:_
R - connect the wiring as necessary to get the correct phase
R sequence.
R 2 If the wiring is correct and the fault continues:_
R - replace the external power source.
R B. Make sure that the aircraft electrical circuits operate correctly in
R external power configuration.
R (1) Energize the Aircraft Electrical Circuits from the external power
R (Ref. AMM TASK 24-41-00-861-002).
R (2) De-energize the aircraft electrical circuits from the external power
R (Ref. AMM TASK 24-41-00-862-002).

R A. If the fault symptom is identified by the CFDS message WRG: POR/ WRG: APU
R GEN FEEDER/ GAPCU (24XG) and the upper ECAM-DU warning APU GEN FAULT:
R - do a check of the Point-Of-Regulation (POR) sense wiring (Ref. ASM 24-R 23/01) for a correct phase connection between:
R . terminal F of the APU GLC (3XS) and pin A/14G of the GAPCU (phase A)
