The 5-pole terminal strip is used for connecting up a 24 V voltage
supply and a bypass contactor.
The connection base is located easily accessibly 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
bypass contactor.
The connections for the contactor control are floating.

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 must meet the requirements for safety
separation (PELV electrical circuit = Protective Extra Low Voltage).
