Installation instructions

Safety instructions
Only qualified technicians may assemble and connect electri-
cal devices!
Ensure that the power supply has been disconnected! Discon-
nect the mains plug!
Only use the specified cable cross-sections and fuses of the
correct strength!
After it has been installed, the device must be disconnected
from the mains. This can be achieved by making the mains
plus (cold device plug / X0) accessible after installation or by
installing a switch (all-pole separation) in the permanent instal-
lation in agreement with the local installation regulations.
The installation of the device must comply with the techni-
cal and administrative provisions of the respective country
in which it is used (e.g. EN 1648). National regulations and
guidelines must be observed.
Assembly
(See page 2, fig. B).
The device should be installed away from damp and wet. The
installation site should be clean, dry and well ventilated. Dur-
ing operation, the casing can heat up to around 80 °C.
Ensure that the ventilation slits remain free! Inadequate
ventilation can cause the device to overheat!
The installation space for the device must have ventilation
openings at the top and side that provide a total opening sur-
face of 100 cm².
Secure the device with four screws (diameter 5 - 6 mm – not
countersunk head screws). The screw length and torque de-
pend on the underlying surface.
Connection
Before connecting or disconnecting from the cables,
ensure that the power supply is completely interrupted!
To do this, disconnect the mains or couplig plug from the tow-
ing vehicle and disconnect the battery.
Cable lengths and cross-sections
Model complies with EN 1648-1 und VDE 0100, Part 721.
Consumer connection
Check that the terminals are connected correctly.
Always position the fuses close to the energy source
(e.g. battery, dynamo, charger). Only use the specified
cable cross-sections and fuses of the correct strength!
Cable fixing
Secure all cables (e.g. to energy sources, consumers and
accessories) with cable ties (see page 2, fig. D).

Main supply connection
The device must be connected to the mains power supply in
accordance with the local installation regulations.
The 230 V electrical connection must always be made by an
expert (in accordance with VDE 0100, part 721 or IEC 60364-
7-721, for example, in Germany).
Connect the power cable to the main distributor of the cara-
van. Green/yellow cable to the protective earth!
– Check all connections are tight.
– Create the network connection via the female device plug
with the 230 V mains cable.
