SIMOVERT MASTERDRIVES
The 5-pole terminal strip is used for connecting up a 24 V voltage
supply and a main or bypass contactor.
The connection base is easily accessibly located on the DIN rail below
the slide-in unit of the electronics box.
The voltage supply is required if the inverter is connected up via a main
or bypass contactor.
The connections for the contactor control are floating.

Table 7-4 Connection of external DC 24 V aux. voltage supply and main contactor
control (Type K)
The excitation coil of the main contactor has to be damped with
overvoltage limiters, e.g. RC element.
The 230 V fan has to be supplied with AC230 V externally. The
connecting points are located on the fuse-disconnectors on the right
next to the DIN rail of X9.
The external 24 V voltage supply has to meet the requirements of safe
electrical isolation (PELV current circuit = Protective Extra Low
Voltage).
