ELECTRICAL CONNECTIONS
•
It is advisable to make all connections with flexible electric wire.
• The conductor minimum section must be 1,5 mm2.
• 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.
• Observe the wiring diagram included in the manual.
