The three-phase power supply line must have a switch with
fuses. The regulations further require a switch on the burner's po-
G
wer supply line, outside the boiler room and in an easily accessed
position. For the electrical connections (line and thermostats),
L
follow the wiring diagram enclosed. To carry out the connection of
the burner to the power supply line proceed as follows:
I
1) Remove the lid by unscrewing the 4 screws (1) in figure 1,
S
without removing the transparent door. In this way the burner's
H
electrical panel can be accessed.
2) Slacken le screws (2) and, after removing the cable float (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 holder.
3) Reposition the cable float as in figure 3. Turn the cam (6) so
that the float exerts sufficient pressure on the two cables, then
tighten the screws that fasten the cable float. Finally, connect
the two 7 and 4-pole plugs.
IMPORTANT: the housings for the cables for the 7 and 4-pole
plugs are provide respectively for cable Ö 9.5÷10 mm and
Ö 8.5÷9 mm, this to make sure the protection rating is IP 54
(standard IEC EN60529) for the electrical panel.
4) To reclose the electrical panel lid, tighten the 4 screws (1) with
a torque of about 5 Nm to ensure the correct seal. At this point ,
to be able to access the control panel (8), unfasten the transpa-
rent door (7), using slight touch pressure in the direction of the
arrows in figure 4, move it the short distance to separate it from
the lid.
5) to properly resecure the transparent door on the panel proceed
as indicated in 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.

Important: only qualified technicians may open the burner's
electrical panel.
