Notes for power supply on trailers
Often trailers don’t have a stable power supply, or they don’t have a battery at all. In these cases
it’s necessary to power the system using a 220V/12V voltage transformer connected, directly to the
main line. Do not use in any circumstance battery chargers, economic transformers or non-
stabilized power packs. The voltage that feeds the system must be electronically stabilized and
must have a nominal voltage of 13.8V, with a minimum nominal current of 6A.
In the following picture is displayed the electric diagram.
When the system has been connected correctly to a power supply, an auto test will be performed.
If an error message appears on the display, look up the cause specified in the user manual.
6.8. Protection circuit
IMPORTANT
In order to avoid damages by inadvertently driving with the external unit folded-up, connect the
yellow cable to the +15 vehicle line or the D+ line that carries voltage when the engine is on and
no-voltage when the engine is switched off. In this way the external unit will be automatically
retracted when the caravan engine will be switched on.
6.9. Cabling between control and command units
Connect the 5mt cable between the control and the command unit; take care of inserting the RJ11
connector in the right direction and push them until you here a click. If the cable is too long, coil it
up near the control unit, fixing it appropriately.
