ELECTRICAL CONNECTIONS
The three-phase power supply line must have a switch with fuses.
The regulations further 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 at-
tached wiring diagram. To carry out the connection of the burner to
the power supply line proceed as follows:
•
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.
•
Loosen the screws (2) and, after removing the cable float 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 holder.
•
Reposition the cable float as shown 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.
!
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.
•
To close the electrical panel cover, tighten the 4 screws (1) with
a torque of about 5 Nm to ensure the correct seal. At this point,
to access the control panel (8), unfasten the transparent door
(7), pressing gently in the direction of the arrows shown in figure
4, slide it a short distance to separate it from the cover.
•
To secure the transparent door on the panel properly, 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.
!
only professionally qualified technicians may
open the burner electrical panel.
