Components in separate electrical cabinets or components not installed in an electrical cabinet
A two-channel cable connection is required when installed in separate electrical cabinets - or
when connecting components not installed in an electrical cabinet to an electrical cabinet. You
must protect the cables between the I/O modules and the inverter against cross and short-
circuits - or ensure that a cross or short-circuit results in a discrepancy error.
