12.1 Circuit diagram / wiring variant
The following circuit diagram shows a wiring vari-
ant of the AKM busbar tap-off unit.
The wiring depends on the selected AKM variant
and thus on the installed measurement devices
and components.
The figure shows only one example. The enclosed detailed circuit
diagram is definitive (depending on measurement device, current
and options)
