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.
• 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.
To carry out the connection of the burner to the power supply line
proceed as follows:
• Remove the cover by unscrewing the screws (1), without removing
the transparent door. In this way the burner’s electrical panel can
be accessed.
• Undo the screws -6. Remove the lid to access the burner's electrical
panel.
• Loosen the screws-10 to release the cable retaining plate -11,
route the equipment supply cable and the modulation control cable
through the relevant holes. Connect the motor power supply cables
-1 to the contactor, fix the earth cable -2 and close the cable gland.
In the case of a single-phase burner, only the cables L (phase) and
N (neutral) corresponding to positions L1 and L3 are connected to
the remote control switch.
CAUTION / WARNING
The housings for the cables for the 7 and 4-pole plugs are
provided respectively for cable Ø 9.5÷10 mm and Ø 8.5÷9
mm, this ensures the protection rating is IP 44 (Standard IEC
EN60529) for the electrical panel.
