ELECTRICAL CONNECTIONS

The three-phase power supply line must have a switch
with fuses. The regulations further require a switch on the
burner's power supply line, outside the boiler room and in
an easily accessed position. For the electrical connections
(line and thermostats), follow the wiring diagram enclosed.
To carry out the connection of the burner to the power sup-
ply 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) 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
Ø 9.5÷10 mm and Ø 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
transparent 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
