1. A system for providing a supply voltage for an electrical consumer, comprising:
a generator (1);
an internal combustion engine (10) driving the generator (1);
an electrical control unit (30) configured to control the internal combustion engine (10);
an incoming electrical line (24) for supplying an operating voltage (U) to the electrical control unit (30);
an operating unit (20, 22) that is necessary for operating the internal combustion engine (10);
an outgoing electrical line (21, 23) connecting the electrical control unit (30) to the operating unit (20, 22);
a breaker (41) arranged in the incoming electrical line (24) or the outgoing electrical line (21, 23); and
a CO sensor (42) that controls the breaker (41),
wherein the CO sensor (42) is configured to open the breaker (41) and interrupt the incoming electrical line (24) or the outgoing electrical line (21, 23) when a predeterminable CO limit value is exceeded and thereby shut down the internal combustion engine (10), and
wherein the electrical control unit (30) is configured to control the internal combustion engine (10) by controlling the operating unit (20, 22) via the outgoing electrical line (21, 23).
