Default I/O diagram of the inverter control unit (A41)
The diagram below shows the default I/O connections on the inverter control unit (A41),
and describes the use of the connections in the inverter 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).
