Electric power is transferred to an electric load as alternating current over at least two incoming and outgoing lines. At least one line circuit manages at least one parameter of the transferred electric power. A central circuit exchanges data and/or commands with the at least one line circuit over a respective galvanically isolated communication interface, such that a reference potential of the central circuit is floating relative to an earth potential of the at least two incoming and outgoing lines. A respective surge protection capacitor is arranged in parallel with each galvanically isolated communication interface. The surge protection capacitors are configured to accumulate a respective fraction of an electric charge resulting from an undesired overvoltage on one of said incoming lines so as to split up the undesired overvoltage into two or more voltages over the galvanically isolated communication interfaces each of which voltage is smaller than the undesired overvoltage.
