WIRING DIAGRAM (DACA VERSION)
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 po-
sition. 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) Remove the lid by unscrewing the 4 screws (1) in figure 1. In
this way the burner's electrical panel can be accessed.
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 contactor, 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
the two 7 and 4-pole plugs.
Important: the housings for the cables for the 7 and 4-pole plugs
are respectively for cable Ö 9.5-10 mm and Ö 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
electrical panel.
