so2 evacuation for middle voltages

The vehicle's electrical system works with direct current and a voltage of 24 V, supplied by two 12 V batteries with a capacity of 110 Ah each and an A/C generator (80 A) with a voltage of 28 V. The main switch (cutoff switch) for the electrical circuits, emergency parking and reverse gear of the vehicle is in the driver's cab.
