D) Connecting The Loudspeakers And The Power Supply - Renkforce RUSD-1803 Operating Instructions Manual

d) Connecting the loudspeakers and the power supply

Vehicles equipped with an ISO system plug can be connected directly to the ISO terminal if the plug assi-
gnment is the same (please check beforehand!). If the plug assignment differs, the connection is made with
a vehicle-specific adapter available in stores.
Please refer to the following illustrations for the contact assignment of the ISO connection socket of the
car radio. Please ask you car dealer for the respective assignment of your vehicle system plug.

System plug A (power supply)
(1) not reserved

(3) not reserved
(4) Continuous current +12 V
(5) Aerial control output
(6) not reserved
(7) Ignition +12 V
(8) Ground
• The constant current terminal +12 V (4) must be connected to a cable that also supplies +12 V perma-
nently when the ignition is off (terminal 30 of the on-board network). This terminal serves to save the user
settings, time, etc.
• The aerial control output (5) supplies a voltage of +12 V when switched on. This contact be used as
power supply of an electric aerial and as switch-on voltage for a car amplifier.
• The terminal of the ignition +12 V (7) must be connected to a cable that is only live with +12 V when the
ignition is on (terminal 15 of the on-board networks).
Do not connect this terminal to continuous current, otherwise the on-board battery could be
discharged when the vehicle is parked for a longer period of time.
• Connect the ground connection (8) with the vehicle body.
Adhesive techniques which become ever more common and painted metal parts impair the elec-
tric conductivity. Therefore not every metal part is a suitable earthing point.
