230 V Electrical Connection; Control Panel Connection; Power Supply; Function Check - Truma BG 10 Einbauanweisung

The boiler fuse (36), 1.6 A (slow-acting), is on the elec-
tronic control unit.
Screw on the cover (34).
Figure 14
When power packs or power supply units are being used,
make sure that the regulated output voltage is between
11 V and 15 V and the alternating current ripple is < 1.2 Vss.
230 V electrical connection
The 230 V electrical connection must always be made
by an expert (in accordance with VDE 0100, part 721 or
IEC 60364-7-721 in Germany). These instructions are intended
only as additional information for a qualified electrician; electri-
cal work should not be carried out by unqualified persons.
Make the connection to the 230 V
3 x 1.5 mm² cable (e.g. H05VV-F flexible cable) and the connec-
tion to the 230 V control panel using a 4 x 1.5 mm² cable.
It is imperative that connection is carried out with care while
observing the correct colours.
An insulating device for providing all-pole insulation from
the mains with contact clearance of at least 3.5 mm must be
provided by the customer for carrying out maintenance and
repair work.
All cables must be secured with clamps. The heating el-
ement cables can be routed next to the support on the
side of the boiler and attached to the lug by means of a cable
tie. No water containers or hoses must be attached to the lug.

control panel connection

Connect the cable for the control panel, the 230 V cable and
the cable for the heating element as shown in the diagram
below.
The cables must comply with the technical rules and regula-
tions of the country in which the vehicle is registered.

In the interests of safe operation, make sure that the L and N
conductors are properly connected to the corresponding cables.

Function check

Following installation, the gas system must be checked for
leaks in the first inspection by using the pressure drop meth-
od in accordance with EN 1949.
In order to check that the 230 V heating elements are oper-
ating correctly, a power consumption measurement must
be carried out with the switch in the 850 W and 1300 W
positions.
Position 850 W 3 – 4 A
Position 1300 W 5 – 6.5 A
If the values measured do not fall within the range shown
above, please check that the heating elements are properly
connected.
Then check all appliance functions as described in the oper-
ating instructions – especially the boiler draining function. No
claims may be made under the warranty for damage caused
by frost!
Never operate the boiler when it is empty! An electrical
function check can be carried out briefly even if there
is no water in the boiler. Always follow the operating instruc-
tions before starting up.

Warnings

The installer or vehicle owner must affix the yellow warning
information sticker that is provided with the appliance to the
vehicle in a location that is clearly visible to all users. Missing
stickers can be requested from Truma.
