Functional instructions for connection to the on-board power supply
Warning
Danger of cable fires. Never bypass the fuses in the cable and in the receiver
● At the connecting point for the power cable, the voltage must not fall below 11.5 V even with a load of
12 A. Otherwise optimum functioning can no longer be guaranteed.
● Connect the power cable to the respective socket in your motor home or caravan (12 V or 230 V).
Only for connection in a motor home, not in a caravan!
● The third, green connecting cable, marked “IGNITION” allows you the option of connection to a circuit in
the vehicle that is activated when the ignition key is turned and then carries a continuous 12 V supply.
This type of connection ensures that when the engine is started the antenna is automatically lowered
into the park position (the receiver does not need to be turned on).
Note that the antenna can then be lowered only when the power supply is present in addition to the
ignition signal!
● Check the connections before you re-connect the on-board power supply.
● For commissioning and more detailed information on additional operator functions, please consult the
operation section of the separate operating manual for the receiver.
Under certain circumstances, problems can arise when the units are connected to different connecting sock-
ets or circuits/earth potentials. If no others are available, it is recommended that you connect the connecting
sockets for receiver and TV set to the same cable, as shown in Fig. G. The power rating of the circuit used
must be checked with respect to the intended application.
Further information on operating the UFS 946/CI+ receiver can be found in the operating manual supplied
with the unit.
