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 connection 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 connections to the grid 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
To access the electrical components inside the control panel, follow the sequence in fig. 3 - 4 - 5 - 6.
The layout of the terminals for the various connections is given in the wiring diagrams in the technical data chap-
ter.
