➤
To relieve strain on the supply line, secure it with a cable tie, e.g. to
the cab roof.
NOTICE!
Do not exceed the specified torque under any circumstances. This is the
only way to ensure that the thread inserts are not torn out.
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!
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).
NOTE
The unit is equipped as standard with a 4 m long cable with a cross-
section 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.
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
