Abstract
A control device actuates at least one fuel injection valve with a high voltage and a comparatively lower voltage in temporally consecutive phases. The control device has supply connections for supplying energy from a motor vehicle battery. One of the connections is connected to vehicle ground. First output connections provide a positive first output voltage with respect to vehicle ground, the voltage being smaller than or equal to a hazard voltage of 60 volts of direct current according to TRBS2131. Second output connections provide a positive second output voltage with respect to vehicle ground, the voltage being greater than the hazard voltage and smaller than a sum of the first output voltage and the hazard voltage. The positive potentials of the first and second output voltages (U1, U2) are linked together.
