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 the 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 tighten
the screws that fasten the cable float. Finally, connect the two 7
and 4-pole plugs.
the housings of 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 degree is IP 54 (IEC EN60529
Standard) for the electrical panel.
• To close the switchboard cover, tighten the 4 screws (1) to a torque
of approx. 5 Nm in order to ensure proper sealing. Now, to gain
access to the control panel (8), release the clear door (7), by slightly
prising with a tool (e.g. screwdriver) in the direction of the arrows
shown in figure 4, let it slide shortly and then separate it from cover.
• To properly secure the transparent door on the panel again, 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.
