Auxiliary power supply, main contactor

The 5-pole terminal strip is used for connecting up a 24 V voltage
supply and a bypass contactor.
The 24V-voltage supply is required if the inverter is connected up via a
bypass contactor.
The aux. current supply simultaneously ensures communication with
the automation even if the supply voltage of the power section is de-
energized.
The connections for the contactor control are floating.
The position of the terminal strip can be seen from the connection
overviews.

Table 7-3
The excitation coil of the main contactor has to be damped with
overvoltage limiters, e.g. RC element.
The external 24 V voltage supply must meet the requirements for safety
separation (PELV electrical circuit = Protective Extra Low Voltage).
