Default I/O diagram of the inverter control unit (A41)
The table below 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
(22…12 AWG). The tightening torque is 0.45 N·m (4 lbf·in).
