2.08 Electrical connection
The boiler must be connected to a single phase 230V 50Hz electricity supply with a 3 A max. fuse and a bipolar switch with
contact opening of at least 3 mm fitted between the boiler and the electricity supply. The boiler must always be connected
to an efficient earth installation. In the electrical box, there is a 3 pole terminal block for connecting the boiler to the mains
(230V 50Hz) and a 3 pole block for connecting a circulating pump (not supplied). See Wiring diagram (fig. 41a) for the
connection of external control.
When the boiler is connected to an electricity main, it is essential TO ENSURE CORRECT POLARITY (LIVE: brown cable,
NEUTRAL: blue cable, EARTH: yellow-green cable).
All wiring must conform to current I.E.E. regulations.
Note: If the power supply cable has to be replaced, use "0.75mm (24/0.20) cable only to BS6500 with a maximum external
diameter of 8 mm.
