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 four screws (1) in figure 1, without
removing the transparent door. In this way the burner's electrical
panel can be accessed.
• Loosen the screws (2) and after removing the cable clamp plate (3),
make the auxiliaries power cable and thermostatic line cable come
through the hole. (fig. 2). Connect the power supply cables (4) to the
contactor, connect the cable to ground (5) and close the cable holder.
• Reposition the cable clamp plate (fig. 3). Turn the cam (6) so that the
cable clamp plate (3) exerts sufficient pressure on the two cables,
then tighten the screws that fasten the plate. Finally, connect the
two 7 and 4-pole plugs.
the housings for the auxiliary devices power cables for the 7 and
4-pole plugs are provided respectively for cable Ø 9.5÷10 mm
and Ø 8.5÷9 mm, this to make sure that the protection rating is
IP 54 (standard IEC EN60529) for the electrical panel.
• To close the electrical panel lid, tighten the four 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 with a tool (e.g. a screwdriver) in
the direction of the arrows (fig. 4), move it the short distance to
separate it from the lid.
• To properly position the transparent door on the panel (fig. 5) proceed
positioning the hooks in 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.
