The battery charger only works if the batteries have been
inserted with their poles in the right direction.
Total discharge protection
If the battery voltage of the ancillary battery sinks below 10.5
V a relay shuts down all equipment using power.
If the total discharge protection is activated turn off the
12V main switch to avoid an additional discharge of the
ancillary battery.
The minimum charging period of 12 hours must be exten

such cases they do not supply electricity to the on-board
circuit or absorb power from the charger. Therefore, when
travelling in winter, the heating should be turned on before
charging the batteries.
The battery voltage of both the motor battery and the
ancillary battery can be checked continuously on the
control panel.
