An electronic device with polarity reversal protected connections and irreversibly interruptible programming connections, wherein the interruption is performed through safety elements provided in the programming paths, behind which safety elements diodes are disposed which block towards ground in normal operation, so that an overload current can be passed through the safety elements and through the diodes to ground through intentional polarity reversal of the respective connections, whereby the safety elements are destroyed and the programming conductors are irreversibly interrupted.
