Maintenance-free batteries
For commercial vehicles, this type of battery does incorporate filler plugs. Take the same
precautions as for ordinary batteries. However, the trickle charging current should not ex-
ceed 1 Amp.
Before using a charger, disconnect the batteries.
If starting with an auxiliary battery, make sure to connect the (+) terminal of the auxiliary
battery to the (+) terminal of the vehicle battery and the (-) terminal of the auxiliary battery
to the (-) terminal of the vehicle battery.
Incidents involving electrical appliances on tractor vehicles are quite often caused by defi-
ciencies in the electrical installations of trailers. Before hitching up a trailer, carefully check
its electrical installation so as to avoid the destruction of fuses, and in particular thee earth
link.
Overloading the electrical system by adding bulbs or supplementary or more
powerful equipment than that for which the system was designed may cause ex-
tremely serious damage to all the equipment installed and may produce abnor-
mal discharging of the batteries. Such action will invalidate the manufacturer's
warranty.
12 Volts power supply
The supply voltage for the installed equipment
must be equal to the vehicle's rated voltage.
Any appliance having a 12 Volts rated voltage
needs the use of a voltage dropper.
Connection to the mid-point of the two
batteries is strictly forbidden.
