Abstract
A system for operating an electric machine and a method for protecting an operation control unit in such a system. The system includes an operation control unit, an alternating current cable connecting the machine with the operation control unit and an electric short-circuiting arrangement. This arrangement is connected to terminals of the operation control unit facing the cable and short circuits these terminals based on a detected overvoltage.
