Electrical Connection - Renkforce CD-7516 Bedienungsanleitung

Electrical Connection

The electric connection should be carried out by a specialist.
To avoid short-circuits and resulting damage to 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.
You should 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 car.
When laying the cables, make sure that they are not jammed or damaged by sharp edges. Use
rubber spouts for the lead-though points.
The cabling to the speakers must be a two-lead cable. Insulate the bare wires at the connecting
terminals. Make sure that there are no sharp edges which could damage the cables.
Only use speakers which have a sufficiently high loading capacity (see „Technical Data")..
Make sure that all speakers have the correct polarity, i.e. the plus and minus signs must match.
The connecting cables for the speakers are usually coded: Some speaker 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 speaker impedances of at least 4 Ohm. Never
connect speakers with a lower impedance.

In most vehicles the cables for the electric connection and the connection of the speakers have been
laid directly to the radio recess.
If this is not the case, please make sure that any cables laid later are secured by the respective on-board
fuses (see vehicle operation manual).
