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

The power lines must be distanced from the hot parts.
•
The burner installation is allowed only in environments with
pollution degree 2 as indicated in annex M of the EN 60335-

Make sure that the power line to which the unit will be connected,
has frequency and voltage values 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.

For the mains supply connection is required an omnipolar switch
with a contact opening gap equal or above 3 mm in accordance
with current safety regulations.

Remove the external insulating seal of the supply pipe necessary
for the connection, preventing the cable to touch metal parts.
