5.12 Electrical connection
(general)
Danger of electric shock!
All electrical work in connection with the installation must only be carried out by a
trained electrician!
- Mains Voltage AC 230 V +6% -10%, 50 Hz
In Germany the VDE and local regulations and in all other countries, the pertinent
regulations should be followed during installation.
The electrical connection has to be carried out unmistakably regarding terminal
and terminal direction. In Germany, the connection can be carried out with an ac-
cessible, unmistakable plug-in connection or as a fixed connection. In all other
countries, a fixed connection has to be carried out.
It is recommended , to install a main switch before the Power HT. This
should switch off all poles and have a contact opening width of at least 3 mm.
All connected components must comply to VDE. Connecting lines have to be in-
stalled strain relieved.
Cable lengths
Bus / sensor cables
do not carry mains voltage, but protective low voltage. They
must not be routed in parallel to the mains cables (interference signals). Otherwi-
se screen cables should be used.
Permissible cable lengths for all sensors:
- Cu-cable up to 20m: 0.8 mm
2
- Cu-cable up to 80m: 1 mm
2
- Cu-cable up to 120m: 1.5 mm

Strain reliefs
All electrical cables have to be installed from the boiler rear wall to the boiler
switch panel. Here, the lines have to be fixed into the strain relief of the switching
panel and to be connected according to the wiring diagram ( Fig. 8 ).
