Installing the electrical supply lines

!
WARNING!
• The electrical power supply may only be performed by qualified personnel
with specialist knowledge.
• Make sure there is no voltage present on electrically operated components
before carrying out work on them!
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 19).
• Cut the connection cable to the shortest possible length. Otherwise the
voltage drop is increased and thereby the air conditioning roof unit's
performance reduced.
I
NOTE
The unit is equipped as standard with a 4 m long cable with a cross-section of
2
6 mm . 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.
When the cable is extended by 4 m to 6 m in length, the manufacturer
recommends using a cross-section of at least 8 mm
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.
