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). The instructions shown here do
not constitute a request to non-experts to make the electrical
connection, but serve as additional information for an expert
who is employed to do the work.
Make the connection to the 230 V power supply using a
3 x 1.5 mm² cable (e.g. H05VV-F flexible cable) and the con-
nection 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
element cables can be routed next to the support on the
side of the boiler and attached to the lug by means of a cable
binder. No water containers or hoses must be attached to the
lug.

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 regul-
ations of the country in which the vehicle is registered.

Function check

The leak tightness of the gas supply line must be tested using
the pressure drop method after installation. A test certificate
must be issued.
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 device 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 instructions
before starting up.

Warnings

The installer or vehicle owner must affix the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, in a location in the vehicle where it is clearly visible
to all users (e.g. the wardrobe door). Missing stickers can be
requested from Truma.
