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 con-
nected has frequency and voltage ratings suitable for the bur-
ner.
•
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 absor-
bed by the burner.
•
The mains supply connection requires an omnipolar switch with
a contact opening gap equal to or greater than 3 mm in accor-
dance 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 bur
-
ner electrical switchboard.
•
In case of unbalanced 230V phase-phase mains supply sy-
stems, 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 tran-
sformer type AR1 code 0005020028 which must be connected
as shown in the following diagram.
