(2) If the circuit breaker is open:
- close it.
(a) If it trips:
- do a check of the wiring for a short to ground between respectively the pins A/2, B/2, C/2 of the circuit breaker (2PU2) and the pins 22, 23, 24 of the module 20XX (Ref. ASM 24-32/01).
1 If the wiring is not correct:
_ - repair it.
2 If the wiring is correct:
_ - replace the C/B-TR2 SPLY (2PU2).
