The three-phase power supply line must have a switch with fuses.
The standards also require a switch on the burner's power line
located outside the boiler room where it can be accessed easily.
Refer to the wiring diagram for electrical connections (line and
thermostats). To connect the burner to the supply line, proceed
as follows:
• Remove the lid by unscrewing the 4 screws (1) (fig.1). 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). In
the case of a three-phase burner, connect the power supply
cables (4) to the contactor, fix the ground cable (5) and tighten
its cable holder.
• Reposition the cable clamp plate (fig. 3). Turn the cam (6) so
that the plate exerts sufficient pressure on the two cables, then
tighten the screws that fasten the plate. Finally, connect the two
7 and 4 pole plugs (figure 4).
The housings for the cables for the 7 and 4-pole plugs are
respectively for cable Φ 9.5-10 mm and Φ 8.5-9 mm, this
to ensure an IP 44 (IEC EN 60529) protection rating 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.
Only qualified technicians are allowed to open the burner
electric panel.
