<p>The arrangement (1) has a control logic (3) controlling an electric motor (2), and two power supplies (4, 5) for plugging in the arrangement to a DC voltage supply network of a vehicle. A circuit arrangement (6) is formed for documenting a series connection consisting of a diode (7) and a fuse element (9). The series connection is loaded while connecting the power supplies with voltage such that the diode closes during correct polarity of the power supplies, and the fuse element is opened to disrupt the current flow during wrong polarity of the power supplies.</p> |
