12 V

voltage supply

Electrical lines, switching and control equipment for heaters
must be in locations that will not cause the operation thereof
to be adversely affected under normal operating conditions.
The breakthroughs of all lines leading to the outside must be
protected from splash water.
Disconnect the appliance from the power supply before start-
ing to work on electrical components. Switching off at the
control panel is insufficient!
The equipment must be disconnected from the on-board
power supply when electric welding work is being carried out
on the body.
The unit has reverse polarity protection. The LED indicator
will not work if the unit is connected with incorrect polarity.
The unit can be used after establishing proper polarity.
In order to ensure that an optimum power supply is pro-
vided, the heater must be connected to the fuse-protected
on-board power supply (central electrical system 10 A) with
2 x 2.5 mm² cable (2 x 4 mm² with lengths exceeding 6 m).
Voltage drops in the supply line must be taken into consider-
ation if necessary. Connect negative line to main ground con-
nection. If the equipment is connected directly to the battery,
the positive and negative lines must be protected. For the
connections (40, 41), we recommend 6.3 mm fully insulated
flat connectors.
No other consumers must be connected to the supply line!
When power packs or power supply units are being used,
note that the regulated output voltage is between 11 V
and 15 V and the alternating current ripple is < 1.2 Vpp. We
recommend the automatic chargers from Truma for the various
applications. Please contact your dealer. Other chargers may
only be used in conjunction with a 12 V battery as a buffer.

Room temperature sensor

Attach plug of connector cable to connection (46) (no need to
observe polarity).

Control panel / air conditioning system

The following connection combinations are possible.
Analogue control panels
1 CP classic
control panel
or
1 CP E classic
power selector switch
Digital control panels
1 CP plus control panel
and
1 Air conditioning
system
Insert the plug of the connector cable into one of the connec-
tions (47 or 48) and engage.

Power supply 230 V

(Combi E – with electrical heating elements)
The 230 V electrical connection must always be
made by an expert (in Germany for example in accord-
ance with VDE 0100, part 721 or IEC 60364-7-721).
The 230 V electrical connection must be made on a fused
circuit with a rating of at least 10 A (preferably 16 A).
The following must be provided for the Combi E in the circuit
of the caravan / motor home:
– A suitable residual current circuit-breaker
– Mains disconnect switch (for maintenance and repair work)
These switches must disconnect at all poles and must have
the specified contact spacing (minimum 3.5 mm).

– Cables must be secured using suitable clamps.
– Lay cables / lines of low-voltage systems physically sepa-
rate from those for extra low-voltage systems.

Function check

The leak tightness of the gas supply line must be tested using
the pressure drop method after installation. A test certificate
must be issued (e.g. in accordance with DVGW Work Sheet
G 607 in Germany).
Then check all functions of the device as described in the
operating instructions, particularly the drainage of the water
contents. No claims may be made under the warranty for
damage caused by frost.
The operating instructions must be handed over to the vehicle
owner.
The year when the equipment was first put into opera-
tion must be indicated with a cross on the type plate.

Warnings

The installer or vehicle owner must affix the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, in a location in the vehicle where it is clearly visible
to all users (e.g. the wardrobe door)! Missing stickers can be
requested from Truma.
