Connection Of The Power Supply - BRAX NOX-4 Bedienungsanleitung

Never bridge fuses or replace them with fuses with a higher amperage rating as such actions can destroy both of
the amplifier and the entire electrical system of the vehicle.
Install the cabling in a manner which preludes any danger of the leads being exposed to shear, crushing or rupture forces.
If there are sharp edges in the vicinity (e.g. holes in the body work), all cables must be cushioned and protected to prevent
fraying. Never lay the power supply cables adjacent to leads and lines connecting other vehicle equipment (fan motors, fire
detection modules, gas/petrol lines etc.). In order to ensure safe installation, use only high-quality connection materials.
As an aid to calculating the cross-sectional requirements of power cables which are not longer than 5 m, we recommend
max. 5 A per mm². For the amplifier BRAX NOX4 we suggest a minimum cross section of 25 mm² for the positive 12-volt
supply lead and for the ground (chassis) cable. The remote lead should have a cross section of at least 1 mm². In order to
ensure the ideal sound quality and a distortion-free music rendition, please make sure that all cables are securely fixed in
the respective terminals.

Connection of the power supply

1 Connecting the remote lead
The remote lead is connected to the automatic antenna (aerial positive) output of the head unit (radio). This is only activa-
ted if the head unit is switched ON. Thus the amplifier is switched on and off with the head unit.
2 Connecting the battery cable
Connect the +12 V power cable to the positive terminal of the battery. Recommended cross section: min. 35 mm².
3 Connecting the ground cable
The ground cable should be connected to a central ground reference point (this is located where the negative terminal of
the battery is grounded at the metal body of the vehicle), or to a bright bare-metal location on the vehicle chassis, i.e. an
area which has been cleaned of all paint residues.
