7.2 Auxiliary power supply, main contactor or bypass
contactor
Types E, F, G: The 5-pole terminal strip is used for connecting up a 24 V voltage
X9 - external supply and a main or bypass contactor.
DC 24 V
The voltage supply is required if the inverter is connected up via a main
supply, main
or bypass contactor.
contactor control
The connections for the contactor control are floating.
The position of the terminal strip can be seen from the connection

NOTE The excitation coil of the main contactor has to be damped with
overvoltage limiters, e.g. RC element.
WARNING The external 24 V voltage supply has to meet the requirements of safe
electrical isolation (PELV current circuit = Protective Extra Low
Voltage).
