Abstract
A device includes a first supply unit, which is connectable via a first switch element to a first consumer, a second supply unit, which is connectable via a second switch element and via one or more electric delimitation elements to the first consumer, and a third switch element, which is configured to bridge the one or more electric delimitation elements. A control unit is configured to cause the first switch element to close, and the second and third switch elements to open, in normal operation. The control unit is further configured to detect that a first supply voltage at the first supply unit has reached or fallen below a voltage threshold value, and in response causes first the second switch element to close, then the first switch element to open, and then the third switch element to close, such that the first consumer is coupled to the second supply unit.
