ELECTRICAL CONNECTIONS

The three-phase power supply line must have a switch with fuses.
Furthermore, the Standards require a switch on the burner power
supply line, outside the boiler room and in an easily accessible
position. For the electrical connections (line and thermostats),
follow the attached wiring diagram. To carry out the connection of
the burner to the power supply line proceed as follows:
1) Remove the lid by unscrewing the 4 screws (1) in figure 1,
without removing the transparent door. In this way the burner's
electrical panel can be accessed.
2) Loosen the screws (2) and, after removing the cable clamp
plate (3), pass the two 7 and 4 pole plugs through the hole (see
figure 2). Connect the power supply cables (4) to the contactor,
connect the cable to ground (5) and close the cable gland.
3) Reposition the cable clamp plate as in figure 3. Turn the
eccentric (6) so that the plate exerts sufficient pressure on the
two cables, then tighten the screws that fasten the plate. Finally
connect the two 7 and 4 pole plugs.
The housings for the cables for the 7 and 4-pole plugs are
provided respectively for cable Φ 9.5÷10 mm and Φ 8.5÷9
mm, this ensures that the protection rating is IP 54 (Standard
IEC EN60529) for the electrical panel.
4) To close the switchboard cover, tighten the 4 screws (1) to
a torque of approx. 5 Nm in order to ensure proper sealing.
Now, to gain access to the control panel (8), release the clear
door (7), by slightly prising with a tool (e.g. screwdriver) in the
direction of the arrows shown in figure 4, let it slide shortly and
then separate it from cover.
5) To secure the transparent door on the panel properly, proceed
as indicated in figure 5: position the hooks at their hooking
points and (9) slide the door in the direction indicated by the
arrow until it clicks. It is now well sealed.
Only professionally qualified personnel may open the burner
electrical panel.
