Electric Connection - Renkforce CD-3308 Bedienungsanleitung

Electric Connection

The electric connection should be done by a specialist.
To avoid short-circuits and resulting damages of the CD tuner, the negative pole (ground) of the
vehicle battery must be disconnected during connection.
Only connect the negative pole of the battery, when you have completely connected the system
and checked the connections.
If you want to test the voltage in on-board lines, only use a voltmeter or a diode test lamp, since
regular test lamps consume too much current and could damage the electronic on-board
system.
When laying the cables, make sure they are not bent or jammed or chafing at sharp edges.
Please use rubber bushings at the penetration spots.
The line towards the loudspeakers must be a bifilar cable. Insulate the open connections. Make
sure that no wires can be damaged by sharp edges.
Only use loudspeakers with a sufficient power rating (see "Technical Data").
Make sure that all loudspeakers have the correct polarity, i.e. the plus and minus signs must
match.
The connecting cables of the loudspeakers are usually coded: Some manufacturers mark the
(+) line with an additional colour band. Others use a corrugated line for the (+) pole and a smooth
one for the (-) pole.
The system was designed for the operation at loudspeaker impedances of at least 4 Ohm.
Never connect loudspeakers with an inferior impedance.

In most vehicles the cables for the electric connection and the connection of the loudspeakers have
been laid directly to the installation recess.
If this is not the case, please make sure that any cables placed later are secured by the respective on-
board fuses (see vehicle operation manual).
