Reaction:
ACOPOS: See error number 7211.
ACOPOSmulti: None.

Cause/Remedy:
See Power unit

Mains wiring error: Loose contact or mains phase not attached. -> Check wiring and voltages on the mains connection.

Mains phase failure: Check the contactor, fuse, transformer and supply voltage.

DC bus feed or single-phase operation: If the ACOPOS module is supplied by the DC bus or single-phase, then the phase monitor must be ignored (PHASE_MON_IGNORE = 1). Caution: These operating modes are only conditionally permissible.
