Abstract (en)
The arrangement has a comparator circuit (10) for comparing voltage potentials (U6, U7) within the arrangement. A deactivation apparatus (16) is provided for deactivating a drive circuit (18). The comparator circuit is designed to activate the apparatus if the difference between the voltage potentials exceed a predeterminable limit value during operation of lamps (LP1, LP2) using radiofrequency signal.
