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, out-
G
side the boiler room and in an easily accessed position. For the electrical
L
connections (line and thermostats), follow the wiring diagram enclosed.
To carry out the connection of the burner to the power supply line proceed
I
as follows:
S
1) Remove the lid by unscrewing the 4 screws (1) in figure 1. In this way
the burner's electrical panel can be accessed.
H
2) Slacken screws (2) and, after removing the cable float plate (3), pass
the two 7 and 4 pole plugs through the hole (see figure 2). In the case of
a three-phase burner, connect the power supply cables (4) to the contac-
tor, fix the ground cable (5) and tighten its cable holder.
3) 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
4-pole plugs.
Important: the housings for the cables for the 7 and 4-pole plugs are re-
spectively for cable Φ 9.5-10 mm and Φ 8.5-9 mm, this to make sure the
protection rating of IP 44 (IEC EN 60529) 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.
Important: only qualified technicians may open the burner's electri-
cal panel.
The electric motor is equipped with thermal protector with automatic reset
that stops the unit in case of overheating.
CAUTION / WARNING
In case of lock out it is necessary to check that the motor is not faulty
and search for the possible causes of its heating.
