ELECTRICAL CONNECTIONS
• It is advisable to make all connections with flexible electric wire.
• 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.
CAUTION / WARNINGS
Only professionally qualified personnel may open the
burner electrical switchboard.
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.
• Undo the screws (2) and, after removing the cable retaining
plate (3), make the two 4- and 7-pole connectors go 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.
