ELECTRICAL CONNECTIONS

The burner installation is allowed only in environments with pollution degree
2 as indicated in annex M of the EN 60335-1:2008-07 regulation.
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 accessible position. For the
electrical connections (line and thermostats), follow the enclosed wiring
diagram. To carry out the connection of the burner to the power supply line
proceed as follows:
• Remove the cover 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 (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 plate 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.
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 close the electrical panel lid, tighten the 4 screws (1) with a tightening
torque of about 5 Nm to ensure correct tightness. At this point, to turn
on the command panel (8), release the transparent flap (7) exercising
a slight pressure with a tool (for example a screwdriver) in the direction
indicated by the arrows in figure 4, then make it slide and detach it
from the lid.
5) 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 personnel may open the burner electrical
panel.
