2.5 Electrical Connections
Connection to the electrical grid
The boiler must be connected to a single-phase, 230 Volt-50 Hz electric line.
The unit's electrical safety is only guaranteed when correctly connected to an efficient earthing
system executed according to current safety standards. Have the efficiency and suitability of
the earthing system checked by professionally qualified personnel. The manufacturer is not
responsible for any damage caused by failure to earth the system. Also make sure that the
electrical system is adequate for the maximum power absorbed by the unit, as specified on
the boiler dataplate, in particular ensuring that the section of the system's cables is suitable
for the power absorbed by the unit.
The boiler is prewired and supplied with a connector located inside the control panel, arranged for con-
nection to an electronic thermostatic controller (see wiring diagrams in paragraph 4.5). In addition, it is
equipped with a three-pole cable for connection to the electricity line. The mains connections must be
made with a permanent connection and equipped with a bipolar switch whose contacts have a minimum
opening of at least 3 mm, interposing fuses of max. 3A between the boiler and the line. It is important
to respect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making
connections to the electrical line.
Access to the electrical terminal board and internal components of the
control panel
