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.
The boiler is prewired and provided with a Y-cable and plug 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. During installation or when changing the power cable, the earth wire must be left 2 cm longer
than the others.
The user must never change the unit's power cable. If the cable gets damaged, switch off the unit and have it
changed solely by professionally qualified personnel. When changing the cable use solely "HAR H05 VV-F"
3x0.75 mm2 cable with a maximum outside diameter of 8 mm.
