An operating device for an illuminant comprises input terminals (L, N) for being supplied with an AC voltage, output terminals (X1, X2) and a driving circuitry (1, 2) for driving the illuminant (3), when connected to the output terminals (X1, X2). In order to compensate an excessive high voltage between the output terminals (X1, X2) and the protective earth (PE) due to voltage surges at input terminals (L, N), bypass means (4) are provided to bypass a current from one of the output terminals (X1, X2) to protective earth (PE) and/or a neutral terminal (N) of the input terminals (L, N), wherein the bypass means (4) comprise at least one capacitor (C). |
