Gas connection

38
Figure 12
The operating pressure of the gas supply is 30 mbar
and must be the same as the operating pressure of the
appliance (see type plate).
The 8 mm diameter gas supply pipe must be attached to the
connector (38) using an olive connection. The olives must be
selected according to the gas supply pipe used (for copper
pipes: brass insertion sleeves and olive included in scope of
delivery). Carefully counterhold (width across flats 16) with
another wrench when tightening.
Before connecting to the boiler, ensure that the gas lines are
free of dirt, swarf and the like.
The pipes must be installed in such a way that the appliance
can be removed again for service work.
The number of separation points in the gas supply line in rooms
used by persons must be limited to the technical minimum.

Fitting the control panels

When using vehicle-specific or manufacturer-specific
control panels, the electrical connection must be made
according to the Truma interface descriptions (see 230 V elec-
trical connection). Any modifications to the associated Truma
parts will invalidate the warranty and preclude any liability
claims. The installer (manufacturer) is responsible for provid-
ing the user with operating instructions and the information
that is printed on the control panels.
Make allowance for the length of the connector cable (3 m)
when choosing a location. A 5 m cable extension is available
if necessary.

If the control panels cannot be flush-mounted, Truma
can provide a surface-mounted frame (25 – part no.
40000-52600) as an accessory by request.
Install the control panel for gas mode (26) and the control
panel for electrical mode (27) (if any) next to each other if pos-
sible (distance between hole centres: 66 mm).
For each control panel, drill a hole with a diameter of 55 mm
(gas mode) and 50 mm (electrical mode) (distance between
hole centres: 66 mm).
Connect the control panel cable (28) to the control panel for
gas mode (26), then fit the rear blank cover (29) as strain relief.
Connect the control panel using a 4 x 1.5 mm² cable (30, not
included – see "230 V
the cable through the rear cover (27a) and secure using strain
relief.
Push the cable through towards the rear and route the con-
nector cables (28 + 30) to the boiler.
Route the connector cable with connector (28) to the 12 V
electronic control unit (for connection, see "12 V
connection").
Secure both control panels with 4 screws each (31).
At the 230 V
the rear cover closes properly and is securely mounted
between the wall on which the boiler is mounted and the con-
trol panel cover frame. It must not be possible to remove the
rear cover when the control panel is fitted.
Fit the front cover (32).
Truma supplies side parts (33) as accessories to improve
the appearance of the cover frames. Please contact your
dealer.
12 V

electrical connection

Disconnect the appliance from the power supply before
starting to work on electrical components. Switching
off at the control panel is insufficient.
The appliance must be disconnected from the on-board pow-
er supply when electric welding work is being carried out on
the vehicle body.
Reversing the polarity of the connections will result in
a risk of cable fire. Any warranty or liability claims will
also be invalidated.
Plug the control panel cable (28) with the connector (28a) into
the electronic control unit.
In order to attach it securely, route the control panel cable (28)
through the cable guide (28b).
The 12 V electrical connection is made at the clamp (35).
orange = positive 12 V
blue = negative
This is done by pressing from above with a small screwdriver
and pushing the cable in from the front.
Connect to the fuse-protected on-board power supply (central
electrical system 5 – 10 A) using a 2 x 1.5 mm² cable.
33
Connect negative line to main ground connection. For lengths
of over 6 m, use a 2 x 2.5 mm² cable. If the equipment is con-
nected directly to the battery, the positive and negative lines
must be protected.
If necessary, remove the outer cable sheathing at the cover
lead-through.
No other 12 V consumers must be connected to the supply
line.
