12. MAKING THE ELECTRICAL CONNECTIONS
Electrical safety of the appliance is only guaranteed by correct grounding, in accordance with the rules in force.
Connect the boiler to a 230V monophase + ground power supply by means of the three-pin cable supplied
with it and make sure you connect polarities correctly.
Use a double-pole switch with a contact separation of at least 3mm in both poles.
In case you replace the power supply cable t a HAR H05 VV-F’ 3x0.75mm
2
cable with an 8mm diameter max.
IMPORTANT: Check that the overall current drawn by accessories connected to the appliance is less
than 2 A. If the value is greater, a relay must be wired between the boiler control circuit board and the
accessories drawing the higher current.
