Cause : HiHp PrChrg Cntc comes when Precharge Contactor Fault - proper contactor feedback has not occurred. The precharge contactor has probably failed to pick up or the feedback signal has failed. This fault only applies to DC input drives.
• Check precharge circuit wiring.
• Check for loose connections on X50 terminal block and/or the X9 and X15 connectors on the ASIC Board.
