Electric Connection - Renkforce sd 7629 Bedienungsanleitung

Electric connection

The electric connection should be done by a specialist.
To avoid short-circuits and resulting damages of the SD 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.
Only use a voltmeter or a diode test lamp for checking the voltage on the on-board cables as
normal test lamps consume excessive current and can thus damage the electronic system of
the vehicle.
When laying the cables, make sure that they are not squeezed or abraded on sharp edges. Use
rubber grommets for the lead-though points.
The line towards the loudspeakers must be a bifilar cable. Insulate the bare wires at the
connecting terminals. Ensure there are no sharp edges which could damage the cables.
Only use loudspeakers which have a sufficiently high loading capacity (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 loudspeaker manufacturers
indicate the (+) wire by means of an additional colour stripe, others use a corrugated cable for
the (+) terminal and a smooth one for the (-) terminal.
The system was designed for the operation at loudspeaker impedances of at least 4 Ohm. Never
connect loudspeakers with a lower impedance.

In most vehicles the cables for the electric connection and the connection of the loudspeakers have
been laid directly to the mounting slot.
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).
