Replace defective fuses only with a new one of the same type and with the same fuse rating.
CAUTION
DEVICE FUSES
The amplifier module has two device fuses, each with 25 A.
4
+12V
Connect the +12V te12V with the +12V pole of the vehicle’s battery. Use a suitable cable with
a sufficient cross section (refer to section 5 on this page).
1
GND
Connect the GND terminal with a suitable contact ground point on the vehicle’s chassis. The ground
wire must be as short as possible and must be connected to a blank metallic point at the vehicle’s
chassis. Ensure that this ground point has a stable and safe electric connection to the negative “–”pole
of the battery. Check this ground wire from the battery to the ground point if possible and enforce it if
required. Use a ground wire with a sufficient cross section (refer to the table and the recommendations
on the next page) and the same size like the +12V power supply wire.
3
REM
Connect a turn-on signal or the turn-on remote signal of your head unit (REM) with the REM terminal
of the amplifier module. Use therefor a suitable cable with a sufficient cross section (0,5 mm
2
). Hereby
the amplifier module turns on or off with your head unit. If you use the
AUTO TURN-ON
function (refer
to page 23, section 13), the REM terminal does not need to be connected.
2
ADDITIONAL CABLE FUSE (NOT INCLUDED)
Install an extra fuse (not included) for the +12V power cable near the battery to secure the power
cable. The distance between the fuse and the battery should not exceed 30 cm. The fuse size must be
adapted to the cable cross-section of the installed power cable (see table below).
IMPORTANT: The fuse on the battery does not protect the amplifier module, but the cable between the
battery and the amplifier module against short circuits.
