5.1.4 Control lines at the transfer terminal strip
Most control lines, which have to be connected between the switch cabinets, are simply connected to
the transfer terminal strips via plugs. The transfer terminal strips are located in the AC cabinet on the
mounting plate facing the DC / inverter cabinet. The cable bundles to be connected are marked with
target descriptions.
