intended for operating the tire inflation
compressor.
The sockets can be used for accessories, e.
g. lamps or mobile phone chargers with a
maximum current draw of 240 W (20 A).
If you use the sockets for long periods when
the engine is switched off, the battery may
discharge.

on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine.
