b) Take care to cable fixing, in order to avoid oscillations - when the caravan is in motion. Such
oscillations could damage or broke internal wires; along the route to the control unit fix the
cable to the caravan walls using a commercially available cable fixing system.
c)
If the cable is too long, coil it up near the control unit, fixing it in an appropriate way
. The
cable between the control unit and outdoor unit should not be cut, spliced or welded.

Power supply
Provide a sufficient power to the system
.
a) The system must powered by a 12V power supply
b) Connect the power cable directly to battery terminals, avoiding to use a cable that powers
another utility. Often the cable section is not sufficient, to supply the original device (e.g. the
television set) plus the new one. In these conditions the voltage that feeds the unit could not
be sufficient. If this procedure is not applied the system could be damaged or not work in the
appropriate way.
c) The supply cable
for lengths over 4mt.
must have a section of at least 2.5mm
2
. For distances
of 6mt or more, cable section must be at least 4.0mm
2
d) The ideal solution is to install a new dedicated power line.
The protection fuse that must be
installed on this line should be between 10A and 15A.

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.
