Electrical installation
Electrical installation must be carried out in accord-
ance with the applicable regulations, by an author-
ised electrical installer or by someone who is cov-
ered by the company's self-inspection programme!
Cables are dimensioned and installed according to current
electrical installation rules.
Cables must be laid so that it is possible to open the front
and remove the roof plate for service.
For minimum ceiling height, see Technical data.
Low-voltage cables may not be routed adjacent to power
lines as this may give rise to interference.
The boiler and heating system must be filled with water and
vented before the boiler is connected to the power supply.
Do not drill into the boiler's cover plates. Cuttings
can damage the boiler's electrical equipment!
M6 bolts are available for fastening cable trays.
Power supply
Removing the front roof plate facilitates the connection of the
power cables.
• Loosen the screws "a", as well as the square tube that holds
the doors.
• Remove the screws "b" and lift the front edge of the roof
plate so that it is straight up. Then lift the roof plate straight
up.
• Slide cable flanges and gaskets onto the power cables, tie
them up and connect the power cables.
• Screw the cable flanges in place with the gaskets.
• Reassemble.
