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 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. .
• 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.
• Reposition the cable float as in figure 3. Turn the cam (6) so that
the float exerts sufficient pressure on the two cables, then tightethe
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 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.
• 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.
• 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.
only qualified technicians may open the burner's electrical panel.
