Mounting and usage instructions
Page 7 of 12
The assembly plate must be glued to the roof using a commercially available sealing compound.
For the cleaning of the roof and the assembly plate use a special cleaning agent recommended
by the manufacturer of the sealing compound (e.g. SikaFlex 252, Teroson 1K-Pur). After the
sealing compound has been dried, apply the sealing compound to the bottom of the plate and
strongly apply the plate to the roof of the vehicle. If the roof of the caravan does not have the
needed consistency, fix the plate with the tapping screws, in order to obtain a stable and safe
assembly. When finished, block the antenna using the security screw
.
The manufacturer can not
be indicated as responsible for damages caused by an incorrect mounting.
ATTENTION
Do not close the 4 holes in the fixing plate;
they allow the passing of the cable and assure rain outflow.
6.1.4.
Passing the cables through the roof
To pass the cables through the roof use, if available, the system adopted by the manufacturer of
the caravan. If no default manufacturers’ system is available, install an appropriate cable
through. Block the cable between the external unit and the cable through, in order to avoid
movements that can cause cable wear or break. Protect the cable from external weather
conditions using appropriate electrical conduits.
Check carefully the point where cable pass through the roof and the strength of the
blocking screws, if used.
6.1.5.
Cable installation
a) Lead the cables coming from the external unit toward the remote control
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 remote control, fixing it in an appropriate way.
d) For installations with a cable length greater than 4mt, use high quality cables with crimped F-
connectors. The maximum allowed cable length is 10 mt
6.1.6.
Power supply
Provide a sufficient power to the system
.
The system can be powered by a 12V or a 24V power
supply
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 2A voltage transformer, connected directly
to the main line. Do not use in any circumstance battery chargers, economic transformers or
non-stabilized power packs.
Once the system is powered it will perform automatically an internal auto-test. If the Led under
the ON/OFF key flashes with a red light, see the reported errors table at page 11.
