6.2.6 Installing the electrical supply lines
! WARNING!
Make sure there is no voltage present on electrically operated compo-
nents before carrying out work on them!
I
NOTE
The unit is equipped as standard with a 4 m long cable with a cross-sec-
tion of 6 mm
2
. If longer cable lengths are required, then the cable cross-
section must be increased by an authorised specialist workshop:
In this case cut off the cable as closely as possible to the unit
(max. 0.5 m) and then establish a suitable connection with a larger cable
cross-section.
The manufacturer recommends a cross-section of 8 mm
2
for cables
between 4 m and 6 m long.
A NOTICE!
 Fit a fuse of 25 amps to the connection to the vehicle's power supply.
 The battery must be able to supply the required current and voltage
(chapter “Technical data” on page 40).
You can connect the unit to the battery via the lorry's terminal block or
directly. The terminal block is to be preferred for the connection. Ask your
vehicle manufacturer for the specifications of the terminal block.
➤
Lay the supply line and connect it to the vehicle (red line to plus, black
line to minus).
➤ Plug in the supply line plug into the socket of the air conditioning roof
unit supply line.
➤
To relieve strain on the supply line, secure it with a cable tie, e.g. to
the cab roof.
