Electrical Connection - Renkforce cd 7630 Bedienungsanleitung

Electrical connection

The electrical connection should be done by a specialist.
To avoid short-circuits and resulting damage to the device, the negative terminal (earth) of the
vehicle battery must be disconnected during installation.
Only re-connect the negative terminal of the battery when the device is fully connected and after
you have checked the connection.
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 currents and can thus damage the electrical
system of the vehicle.
When installing the cables, make sure that they are not squeezed or worn by sharp edges. Use
rubber grommets at cable feedthroughs.
The loudspeakers must be connected using two-core cables. Insulate the bare wires at the
connecting terminals. Make sure no cables are damaged by sharp edges.
Only use loudspeakers with sufficient capacity (see „Specifications").
Make sure that all loudspeakers have the correct polarity, i.e. the plus and minus signs must
match.
Usually, the connecting cables of the loudspeakers are 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 device has been designed for loudspeaker impedances of at least 4 ohms. Never connect
loudspeakers with lower impedance.

In most vehicles, the cables for the electrical connection and for the connection to the loudspeakers
have been laid directly to the radio slot.
If this is not the case, make sure that any cables laid later are secured by the respective on-board fuses
(see vehicle operating instructions).
