Electrical connections

The electrical safety of the equipment is only ensured when it is correctly connected to an effective earthing system in
accordance with the prevailing safety standards for installations (Italian Ministerial Decree no. 37 dated 22.01.08).
The boiler must be electrically connected to a 230 V single-phase + earth mains supply.
Caution
This connection must be made using a two-pole switch with contact opening of at least 3 mm.
The power supply cable must be a harmonised "HAR H05 VV-F" 3x0.75 mm
Warning
Check that the total nominal consumption of the accessories connected to the appliance is less than 1 A. If it is
higher, a relay must be installed between the accessories and the power circuit board.
6.6.1

Accessing the boiler electrical connection board

To access the boiler components you must unscrew the two screws (1) below the panel, then remove the front panel (2). To
access the electrical connection board, turn the control panel downwards (3) then open the cover (4) by releasing the four
catches (do not use excessive force as this could break the plastic hooks).
