The air distribution panel must not be aligned with the centre of the air
intake opening. The air distribution panel must cover the air intake opening
in the vehicle roof.

The system must be protected by a 100 A fuse on the vehicle side. The cable cross-section must be
determined by the customer in accordance with the cable length.
Refer also to "Copper cables for use in motor vehicles" DIN VDE 0298 Part 4.
a) Disconnect vehicle battery.
IMPORTANT
– Note the vehicle manufacturer's instructions when connecting the
power supply for the air-conditioning system.
– Only adequately dimensioned cables approved for use in motor
vehicles may be used (see Fig. 3.1 or 3.2).
– Work on the electrical system may only be performed by authorized
personnel.
– Rubber grommets must be used when routing cables through metal
sheets.
b) Make and connect the cables as shown in Fig. 3.1 or 3.2.
– Route cables through protective sleeves and secure them appropriately with cable ties.
– The power supply for the system must be connected to the bulkhead (Fig. 2.2) with the cable
bolts provided for this purpose.
IMPORTANT
Correct polarity must be ensured without fail (+ pole: M8 cable bolt,
- pole: M10 cable bolt). The electronic control will be destroyed if the
polarity is reversed!
– Use strain relief material.
NOTE
If the operating elements are not installed in the air distribution panel, the
optionally available cable set for external installation of the operating
elements can be used to extend the connecting cables.
