ELECTRICAL CONNECTIONS
• It is advisable to make all connections with flexible electric wire.
• Observe applicable national and European Standards (e.g. EN
60335-1/EN 50165) regarding electrical safety.
• Connect the devices, without option N or N1, to the power supply
respecting the phase-neutral polarity of the mains.
• Carefully check the cables before commissioning.
• Incorrect wiring can damage the equipment and jeopardise system
safety.
• Makes sure the equipment earth terminal, the metal burner casing
and electrical system earthing are connected properly.
• Avoid laying the detection cable along with the power cables or
ignition cables.
• Use a shorter and straight ignition cable and lay it far from other
conductors to minimise radio interferences (maximum length less
than 2 m and isolation voltage > 25 kV).
• This equipment has internal fuses, however, it must be protected
by means of at least one fuse on the line connection.
• 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.
