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.
The electric motor is equipped with thermal protector with automatic
reset that stops the unit in case of overheating.
CAUTION / WARNING
In case of lock out it is necessary to check that the motor is not
faulty and search for the possible causes of its heating.
