the tower bottom end or in the nacelle.
The power cabinet is an incoming unit for the ACS800-67 wind turbine converter.
The power cabinet contains main switching and disconnecting devices such as main
circuit breaker and stator circuit contactor and connection terminals to the power
supply network and generator stator. The power cabinet is an integral part of the
converter line-up.
