ELECTRICAL CONNECTIONS
• It is advisable to make all connections with flexible electric wire.
• Conductor minimum section must be 1.5 mm².
• Electrical lines must be kept away from 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 electric line to which the unit will be connected
has frequency and voltage ratings 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.
• The mains supply connection requires an omnipolar switch with a
contact opening gap equal to or greater than 3 mm in accordance
with current safety regulations.
• Refer to the wiring diagram for electrical connections (line and
thermostats).
• Unsheathe the external insulating cover of the power cable to the
necessary extent for the connection, thus avoiding the wire from
coming into contact with metal parts.
CAUTION / WARNING
Only professionally qualified personnel may open the burner
electrical switchboard.
• In case of unbalanced 230V phase-phase mains supply systems,
the voltage between the flame detector electrode and earth might
not be enough to ensure the correct operation of the burner. The
problem is eliminated using the isolation transformer type AR1
code 0005020028 which must be connected as shown in the
following diagram.
