Electrical Connection - Renkforce RF-ARA-300 Operating Instructions Manual

• The antenna should be mounted within the upper corner of the windscreen and A-pillar (at the top right from the
driver's perspective).
• Use the picture below to determine the mounting position.
• The black electronics box and antenna wire should be attached to the windscreen and the copper-coloured ground
plane to a metal part of the windscreen frame. Make sure the coating of the metal part of the windscreen frame is
intact in doing so.
• Peel off the protective films and attach the antenna such that the cable outlet faces the covering of the A-pillar.
• Once attached, the antenna should not be subject to any mechanical strain for 24 hours.
• The connecting cables must be guided to the car radio installation recess.

9. Electrical connection

Electrical connection must always be carried out by a specialist.
To avoid short-circuits and resulting damages to the device, the negative pole (ground) of the vehicle
battery must be disconnected during electrical connection. Only connect the negative pole of the battery
when you have completely connected the device and checked the connections.
Use only a voltmeter or a diode test lamp to check the voltage of the vehicle system leads, as regular test
lamps consume excessive voltage and may thus damage the vehicle's electronics.
When laying the cables, make sure they are not squeezed or abraded on sharp edges. Use rubber
grommets for the lead-though points.
The line towards the speakers must be a bifilar cable. Insulate the bare wires at the connecting terminals.
Ensure there are no sharp edges that may damage the cables. Ensure that your speakers have a
sufficiently high power rating (see "Technical data"). Ensure that all the speakers have the correct polarity,
i.e. the plus and minus marks must match. The connecting cables of the speakers 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 speaker impedances of at
least 4 Ohm. Never connect speakers with a lower impedance.
