Fitting The Electronic Control Units; Electrical Connection 12 V; Gas Connection - Truma Trumatic E 2400 Operating Instructions And Installation Instructions

Fitting the electronic control units

Unscrew the cover of the control units (A and B).
The plugs on the electronic control units should only be
withdrawn or plugged in if the supply voltage had been
disconnected beforehand. Pull the plug out straight!
Insert the plug on the control panel cable (1) as shown in the
diagram onto the red terminal strip of the control unit (A).
Insert plug (2) – 20-pin – in the grey terminal strip on the
control unit (A).
Insert plug (3) – 10-pin – in the red terminal strip on the
control unit (B).
If a timer switch or a remote sensor is fitted, its plug
is to be inserted on the black terminal strip (control
unit – A). If several accessory components are being used at
the same time, connection is effected via the multiple box
(Accessories).
Secure the lower parts with two screws at an easily accessi-
ble location, protected against moisture (must not be heated
to above 65 °C).
Screw the cover of the control units into place.

Electrical connection 12 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. Switch-
ing 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 cable
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.

Gas connection

plate).
The gas inlet connection on the E 2400 (Australia) is a 8 mm
connection.
The gas connecti on fitting on the appliance is not to be short-
ened or bent.
To connect, the UNF 1/2" – 20 (SAE Male AN Flare) gas inlet
connection provided with the appliance must be used.
For connection to 8 mm steel piping Dometic povides an
adapter UNF 1/2" x RVS 8, part no. 70020-02700.
Before connecting to the appliance make sure that the gas
lines are free from dirt, chips and such!
Route the pipes in such a way that the appliance can be
removed again for servicing.
Refer to AS 5601/2004 – Gas Installations, for gas pipe sizing.
The gas inlet connection is preinstalled.
Please check for leaks before starting up for the first time.
Check for gas leaks (do not check for gas leaks with a naked
flame), then check that the gas pressure is as follows:
Propane gas: 2.75 kPa
Keep the number of parting connections in the gas supply
line in rooms frequented by people to a technically feasible
minimum.
The gas system must accord with the technical and adminis-
trative provisions of the individual country of use (in Australia,
AS 5601/2004 for motor vehicles). National regulations and
rulings must be respected.
