If the appliance is assembled on the outside of the vehicle,
the electronic control unit must be installed inside the vehicle,
where it is protected against moisture and damage. Drill an
opening of 25 mm diameter in the floor or wall, disconnect
connector (2) of 20-pin cable form the control unit and pass
through the opening. Seal with cable grommet. Re-insert
connector.
In special cases, the electronic control unit can be assembled
on the outside of the vehicle, in a protective box, for the elec-
tronics on the outside (accessory part no. 39950-00).
Electrical connection 12 V / 24 V
Electric cables, switching units and control units for heaters
must be arranged in the vehicle in such a way that their satis-
factory operation cannot be adversely affected under normal
operating conditions. All cables leading to the outside must be
splash proof at the leadthrough opening.
Prior to working on electric components the appliance
must be disconnected from the power supply. Switching
off at the control panel is not sufficient!
When carrying out electric welding work on the body the
appliance connection must be disconnected from the vehicle
electrical system.
If the connections are transposed there is a risk of ca-
ble burning. This also rules out any guarantee or liability
claims!
The red cable is positive, the blue cable is negative!
Connect the appliance to the fused vehicle electrical system
(central electrical system 5 – 10 A) using the 2 x 1.5 mm
cable, for lengths over 6 m use 2 x 2.5 mm
cable to central ground. For direct connection to the battery
the positive and negative cable must be fused. Connections in
Faston terminals, fully insulated (motor vehicle flat connector
system, 6.3 mm).
Do not connect any other consumers to the supply line!
When power packs or power supply units are being
used, note that the output voltage is between 11 V and
15 V and the alternating current ripple is < 1.2 Vpp. We rec-
ommend the automatic chargers from Truma for the different
applications. Please ask your dealer. Other chargers may be
used only with a 12 V battery as a buffer.

After the gas system has been installed, the high-pressure
side must be subjected to a one-off check by a TÜV expert.

Function check
