Abstract

A reverse-polarity protection is disclosed for coupling an electric circuit (2) to an energy and information conducting conductor system (3). At least one coupling path (5) comprises a controllable element (4) as reverse-polarity protection. When an emitter circuit (2) is inductively coupled to the conductor system (3) by means of a converter (6), the working current flows through the winding (7) at the emitter side and through the control electrode of the controllable element, the so-called reverse-polarity protection element (4).
