Installation of the control panels
When using control panels which are specific to the
vehicle or the manufacturer, the electrical connection
must be established in accordance with the Truma interface
descriptions (refer to Electrical connection 230 V). Any modi-
fication made to the Truma components pertaining to this
will lead to the invalidation of the guarantee, as well as to the
exclusion of any claims for liability. The installer (manufacturer)
is responsible for providing instructions for use for the user as
well as for identification printing on the control panels.
When selecting the location, please bear the length of the
connection cable of 3 m. If required, a cable extension of 5 m
can be supplied (please refer to page 14).

If it is not possible to install the control panels flush
with the surface, Truma can provide a surface-mount-
ing frame (25) on request, as a special accessory (part no.
40000-52600).
The control panel for gas operation (26) and (if provided by
Truma) the control panel for electrical operation (27) should be
fitted next to one another if at all possible (distance between
centres of holes 66 mm).
In each case, drill a hole with diameter 55 mm (gas operation)
and 50 mm (electrical operation) – distance between centres
of holes 66 mm –.
Plug the control panel cable (28) to the control panel for gas
operation (26) and then fit on the rear cover cap (29) as a
stress-relieving device.
Connect the control panel with a cable (30) 4 x 1.5 mm² (not
in the scope of delivery – see “Connection 230 V control pan-
el”). Feed the cable through the back cover (27a) and secure
with the strain relief.
Push the cable through to the rear and lay the connection ca-
bles (28 + 30) to the water heater.
Lay the connection cable with the orange multipole connec-
tor (28) to the 12 V electronic control unit (for connection see
“Electrical connection 12 V”).
Secure both control panels with 4 screws (31) each.
On the 230 V control panel it must be ensured, that the
rear cover locks correctly and fixed between the instal-
lation wall and the control panel frame.
The rear protection
cover must not be removable when the control panel is
mounted!
Push on the front cover frame (32).
To round off the appearance of the cover frame, Truma
can provide side pieces (33) as special accessories in
8 different colours (please ask your dealer).
Electrical connection 12 V
Always disconnect the appliance from the power supply prior
to working on electrical components. It is not sufficient to just
switch off at the control panel!
The appliance must be disconnected from the vehicle main
power supply when carrying out any electric welding work on
the vehicle body.
If the connections are transposed there is a risk of
cable burning. This also rules out any guarantee or
liability claims.
Unscrew cover (34) from the electronic control unit. Slide
cable connector of control panel (28a) onto the p.c.b..
Put the cable (28) into the cable guide (28b) to fasten it securely.
The electrical connection 12 V is made at terminal (35).
orange = positive 12 V
blue =
negative
To connect press with a small screwdriver from above and
push in cable from the front.
Connect to fused vehicle mains (central electrical equipment
5 – 10 A) using a 2 x 1.5 mm² cable.
Negative cable to central earth. With lengths of over 6 m use
a cable 2 x 2.5 mm². If connecting directly to the battery, the
positive and negative cable must be fused. Screw cover (34)
back on.
If necessary remove the outer cable mantle around the lead-
through of the cover.
There are to be no other 12 V consuming appliances con-
nected to the supply line!
The water heater fuse
(36), 1.6 A, (slow-acting)
is on the
p.c.b..

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.
