WIRING DIAGRAM

The three-phase power supply line must have a switch with fuses.

The regulations further require a switch on the burner’s power sup-

ply 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 gure 1. In

this way the burner’s electrical panel can be accessed.

- Slacken screws (2) and, after removing the cable oat plate

(3), pass the two 7 and 4 pole plugs through the hole (see gu-

re 2). In the case of a three-phase burner, connect the power

supply cables (4) to the contactor, x the ground cable (5) and

tighten its cable holder.

- Reposition the cable oat plate as in gure 3. Turn the cam (6)

so that the oat exerts sufcient pressure on the two cables,

then tighten the screws that fasten the cable oat. Finally, con-

nect the two 7 and 4-pole plugs.

IMPORTANT: the housings for the cables for the 7 and 4-pole

plugs are respectively for cable Ø 9.5-10 mm and

Ø 8.5-9 mm, this to make sure the protection rating

of IP 44 (IEC EN 60529) for the electrical panel.

- 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 qualied technicians may open the bur-

ner’s electrical panel.
