All cables must be securely attached and must not become
loose or disconnected due to vibration – risk of fire!
12 V
voltage supply
Electric cables, switching units and control units for heaters
must be arranged in the vehicle in such a way that their cor-
rect operation cannot be adversely affected under normal op-
erating 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.
The unit is equipped with reverse polarity protection. If
the unit is connected with incorrect polarity, there will be
no display on the LED. The unit can be used after establishing
proper polarity.
To guarantee optimum power supply, the heating system
must be connected to the fused on-board network (central
electronics unit 10 A) with a 2 x 2.5 mm² cable (for lengths
over 6 m with 2 x 4 mm² cable). If relevant, voltage drops in
the supply cable must be taken into account. Connect the
negative lead to the central earth. If connected directly to the
battery, the positive and negative leads must be fused. For the
connections (40, 41), we recommend 6.3 mm fully insulated
flat connectors.
Do not connect any other appliances 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.
Room temperature sensor
Attach plug of connecting cable to connection (46 – no need
to observe polarity).
Control panel / air conditioning system
The following connecting combinations are possible.
1 CP plus
control panel
and
1 Air conditioning
system
Insert the plug of the connecting cable into one of the
connections (47 or 48) and engage.
Combi 2 E / 4 E (Australia)
(heater with electrical heating
elements)

CP plus control panel operating
instructions
Electrical connection 230 ~ / 240 V ~
– option –
All electrical work and permanent wiring must be car-
ried out by a qualified person in accordance with the
standards AS/NZS 3000, AS/NZS 3001 and all local codes and
regulatory authority requirements.
According to Standard AS/NZS 3001.2008 "Electrical
installations – Transportable structures and vehicles" all
electric circuits must be protected with an RCD (residual cur-
rent device).
It is imperative for the connection to be made with care using
the correct colours!
An insulating device for providing all-pole insulation from
the mains with contact clearance of at least 3.5 mm must be
provided by the customer for carrying out maintenance and
repair work.
Make connection to power supply by attaching 150 cm long
silicon cable to a line that is protected with as least 10 A (16 A
would be better).

All cables must be secured with cable clips.
Function test
After installation, the gas feed line must be tested for tight-
ness by the pressure-drop method.
Then test all functions of the unit as described in the operat-
ing instructions, especially water drainage. No warranty
claims for frost damage will be accepted.
The operating instructions must be handed over to the vehicle
owner.
Warnings
The installer or vehicle owner must apply the yel low sticker
with the war ning information, which is enclosed with the
appliance, to a place in the vehicle where it is clearly visible
to all users (e.g. on the wardrobe door)! Ask Dometic to send
you stickers, if neces sary.
