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!
Supply power 1/N/PE
10% - 15%, 50 Hz max. 140 W, fuse: 6A
Observe the IEE and local regulations.
The electrical connection should be made so that the polarity can-
not be mixed up and is connected correctly.
Electrical Supply
A 230 V 50 Hz AC single phase electrical supply is required. The in-
coming mains supply should be terminated via a double pole fused
isolator to the boiler, see wiring diagram for wiring details. A fused
supply is required. The boiler has a 6.3A internal fuse.
Cable Lengths
Cables for sensors of bus cables do not carry mains voltage, but low
voltage. They should not be put parallel to mains wires (this may
lead to disturbances) otherwise screen cable should be used.
Maximum lengths of wires for all sensors:
– Copper wires up to 20 m
0.6 mm²
– Copper wires up to 80 m
1 mm²
– Copper wires up to 120 m
1.5 mm²
Strain reliefs
All electrical cables must be fed through the holes in the boiler
bottom with the enclosed cable feed-throughs and fixed. Further-
more, the cables have to be fixed in the strain reliefs in the control
panel and connected according to the wiring diagram (fig. 8).
