Abstract
A generator provides a supply voltage for an electrical consumer. It includes an internal combustion engine driving the generator. An electrical control unit has an incoming electrical line for supplying an operating voltage thereto. The control unit further has at least one outgoing electrical line. The outgoing electrical line is connected to at least one operating unit that is necessary for operating the internal combustion engine. In order to switch off the internal combustion engine in the event of an increased CO concentration in the vicinity of the generator, a breaker is arranged in an electrical line of the control unit. The breaker is controlled by a CO sensor, which is designed to open the breaker and interrupt the electrical line when a predeterminable CO limit value is exceeded.
