Fitting The Electronic Control Unit; Electrical Connection 12 V / 24 V; Gas Connection; Function Check - Truma Trumatic E 4000 Mode D'emploi

Push the control panel (8) in until the front face is flush with
the surface.
Fig. 26
If there is no installation section present, the control
panel can be fitted with the flush-fitting installation
frame provided.
If flush mounting is not possible, Truma will supply an on-
surface frame (part no. 39050-11600) as an accessory on
request.

Fitting the electronic control unit

Unscrew the cover of the control unit.
The plug on the electronic control unit 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withdrawn or plugged in if the supply voltage had been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.
Fig. 27
If a timer switch or a fine sensor is fitted, its plug is to
be inserted on the red terminal strip. If several accessory
components are being used at the same time, connection is
effected via the multiple socket (Accessory).
Secure the lower part with two screws at an easily accessible
location, protected against moisture (must not be heated to
above 65 °C).
Screw the cover of the control unit into place.
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 ap-
pliance 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 mm²
cable, for lengths over 6 m use 2 x 2.5 mm² cable. Negative
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

The gas supply's operating pressure (30 mbar) must be the
same as the unit's operating pressure (see type plate).
The 8 mm diameter gas supply pipe must be attached to the
connecting piece with a cutting ring connection. Carefully
counterhold with another spanner when tightening!
The gas connecti on fitting on the appliance is not to be short-
ened or bent.
Prior to connecting the appliance make sure that the gas lines
are free from dirt, chips and such!
Choose to route the pipes in a way that will facilitate remov-
ing the unit for service tasks.
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 Europe,
for example, EN 1949 for motor vehicles or EN ISO 10239
for boats). National regulations and rulings (in Germany, for
example, the DVGW worksheet G 607 for motor vehicles or
G 608 for boats) must be respected.

Function check

After installation, the gas feed line must be tested for tight-
ness by the pressure-drop method. A test certificate (in Ger-
many, for example, in accordance with DVGW Worksheet
G 607 for motor vehicles or G 608 for boats) is to be issued.
All equipment functions must be tested in accordance with
the user manual after installation.
The operating instructions must be handed to the owner of
the vehicle.
Remove the type plate from the operating and installa-
tion instructions and affix it at a position on the heater
which is clearly visible and well protected against damage.
The year of initial operation must be marked on the type plate.

Warning information

The installer or vehicle owner must apply the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, to a place in the vehicle where it is clearly visible to
all users (e.g. on the wardrobe door)! Ask Truma to send you
stickers, if necessary.
