An input of the AC circuit breaker forms an AC input of the arrangement. An output of the AC circuit breaker is connected, at least indirectly by a circuit, to an input of the rectifier. The at least one smoothing capacitor connects a first output of the rectifier to a second output of the rectifier. The first output of the rectifier is connected, at least indirectly by a circuit, to an input of the at least one first isolating relay.
