2.4 Electrical connections

The burner is equipped with multipole sockets for the electrical connections; refer to the wiring diagram
in chap. "4 Technical data and characteristics" for the connections. The connections to be made by
the installer are:
• supply line
• thermostat line
• possible shutdown light and/or hour counter
The length of the connection cables must allow the burner and, if necessary, the boiler door to be ope-
ned. If the burner power cable is damaged, it must only be replaced by qualified personnel.
The burner must be connected to a three-phase 230/400 Volt-50 Hz electric line.
Have the efficiency and suitability of the earthing system checked by professionally qualified
personnel; the Manufacturer declines any liability for damage caused by failure to earth the
system. Also make sure the electrical system is adequate for the maximum power absorbed by
the unit, as specified on the boiler dataplate.
Check the correct motor rotation direction.
