WIRING DIAGRAM (VERSION WITH JACK)
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:
1) In the case of models with mono-phase power supply insert the two
7 and 4 pole plugs in the sockets located below the electrical panel
base as shown in figure 1.
2) In the case of models with three-phase power supply, unscrew the
2 screws (1) and remove the lid, detaching it from the electrical panel
base as shown in figure 2.
3) Connect the power supply cables (2) to the contactor, fix the ground
cable (3) and tighten the cable holder (see figure 3). Connect the two
7 and 4 pole plugs.
4) Re-close the lid taking care to position the two hooks (4) and cente-
rers (5). correctly (see figure 4).
Important: only qualified technicians may open the burner’s electrical
panel.
