ABB ACS880-307LC - Default I;O Diagram of the Supply Control Unit

Default I/O diagram of the supply control unit
The diagram below shows the default I/O connections on the supply control unit (A51), and
describes the use of the connections in the supply unit. Under normal circumstances, the
factory-made wiring should not be changed.
The wire size accepted by all screw terminals (for both stranded and solid wire) is 0.5 …
2.5 mm
2
(24…12 AWG). The torque is 0.5 N·m (5 lbf·in).

Note: If drive is equipped with a liquid cool-
ing unit, the relay output controls the cooling
unit start signal. Then the selection Fault(-
