●
At the connecting point for the power cable, the voltage must not fall below 11.5 V even with a higher load. Otherwise
optimum functioning can no longer be guaranteed.
●
Only for
motor homes
: The third, green core of the connecting cable, marked “IGNITION”, allows the connection to
a circuit in the vehicle that is activated when the ignition key is turned and then carries a continuous 12 V supply
voltage. 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 be lowered only when the supply voltage is present in addition to the igni-
tion signal!
●
Make sure that the 15 A blade fuse was expertly installed to the positive conductor (red) of the power supply cable.
Risk of malfunction and material damage due to reversed polarity!
When connecting the power cables, reversed polarity can lead to thermal overload and damage to compo-
nents when the equipment is powered up. If the earth (-) of the ignition signal and the earth (-) of the
vehicle battery for the turntable do not have the same potential, the automatic antenna lowering does not
function!
►
To ensure a sufficient power supply to the automatic turntable, connect the current-carrying wires (red,
black) directly to the vehicle battery.
►
In order that the antenna is automatically lowered to the park position, connect the green wire to the
ignition and the red and the black wire to the vehicle battery.
►
The blade fuse supplied must be connected between the positive pole of the battery and the red wire
of the turntable.
►
For operation with two batteries, it is necessary to ensure that the ignition signal earth has the same
potential as the vehicle battery earth for the turntable.
►
When connecting the power cables (CAP converter, alphatronics TV set or turntable) to the vehicle
electrical system, make sure that the poles (+ and -) are not reversed.
5.1.8 Functional Instructions for Connection to the On-board Power Supply
Under certain circumstances, problems can arise when the units are connected to different connecting sockets or
circuits/earth potentials. If no others are available, it is recommended that you connect the connecting sockets for the
alphatronics TV set, the receiver or the CAP converter to the same cable, see Fig. G. Check the power rating of the circuit
used with respect to the intended application.
