ELECTRICAL CONNECTIONS
• It is advisable to make all connections with flexible electric wire.
• 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.
