ELECTRICAL CONNECTIONS
•
The power lines must be distanced from the hot parts.
•
The burner installation is allowed only in environments with
pollution degree 2 as indicated in annex M of the EN 60335-
1:2008-07 regulation.
•
Make sure that the power line to which the unit will be connected,
has frequency and voltage values suitable for the burner.
•
The three-phase or single-phase power supply line must have
a switch with fuses. The standards also require a switch on the
burner's power line located outside the boiler room where it can be
accessed easily.
•
The main line, the relevant switch with fuses and the possible
limiter must be suitable to support the maximum current absorbed
by the burner.
•
For the mains supply connection is required an omnipolar switch
with a contact opening gap equal or above 3 mm in accordance
with current safety regulations.
•
Refer to the wiring diagram for electrical connections (line and
thermostats).
•
Remove the external insulating seal of the supply pipe necessary
for the connection, preventing the cable to touch metal parts.
To carry out the connection of the burner to the power supply line
proceed as follows:
•
Remove the cover by unscrewing the screws (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 7 pole plug, the 4 pole plug and the modulation
control cable come through the hole. Connect the power supply
cables (4) to the contactor, secure the ground cable (5) and tighten
the relating cable gland.
•
Reposition the cable clamp plate. Turn the cam (6) so that the
plate exerts sufficient pressure on the cables, then tighten the
screws that fasten the plate. Finally, connect the related plugs and
modulation command cable, if installed.
