Busbars and grounding

The ACS6000 drive contains busbars for various types of connections.
3.8.1

AC busbars

The incoming feeder and motor cables are connected to their
corresponding busbars inside a TEU. In multi-motor drives, several TEUs
are part of the drive lineup.
Depending on drive configuration, the incoming busbars are
interconnected with the ARU or the LSU. The outgoing busbars are
interconnected with the inverter unit(s). Phase designations help
identifying the busbars.
