8.2 Motor circuit diagram

When operated on IT line systems, a protective device should be provided that switches off
the drive system in the case of a ground fault.
In operation with a grounded external conductor, an isolating transformer with grounded
neutral (secondary side) must be connected between the line supply and the drive system.
This protects the winding insulation from excessive stress.
