■ Non-integrated
The drive and the transformer are installed in different locations. The
maximum permitted length for the secondary transformer cables
determines the distance between drive and transformer.
The transformer is equipped with an additional compartment (1). The
compartment is divided into the control compartment (2), and the
terminal compartment
ment is located behind a bolted door.
The protection relays monitor the input phase currents of the two primary
winding systems of the 36-pulse transformers. The pick-up values for
overload and short-circuit are set in the factory and must not be changed.
