3.15 - ELECTRICAL CONNECTIONS
General warnings
The electrical safety of the appliance is guaranteed only when
it has been properly connected to an efficient earthing system
carried out as intended by safety standards in force: pipes of
the gas, water and heating systems are absolutely unsuitable
as earthing electrodes.
It is necessary to verify this fundamental safety requirement.
If in doubt, have the electric system carefully checked by
professionally qualified personnel as the manufacturer is not
liable for damage caused by failure to provide an earthing
system.
Have professionally qualified personnel check that the electric
system is adequate for the maximum power absorbed by the
appliance, indicated on the data plate. Make sure in particular
that the cross-section of the cables is suitable for the power
absorbed by the appliance.
Adapters, multiple sockets and/or extension cords cannot be
used to power the appliance.
Use of any type of component using electric energy requires the
observance of some fundamental rules, such as:
• do not touch the appliance with wet and/or moist parts of the
body and/or in bare feet;
• do not pull the electric cables;
• do not leave the appliance exposed to atmospheric agents
(rain, sun, etc.) unless expressly designed;
• do not allow children or unskilled persons to use the
appliance.
230V electric power supply connection
The electrical connections are illustrated in chapters 3.16, 3.17,
3.18, 3.19 and 3.21 for modulating burners and chapters 3.22,
3.23, 3.24, 3.25 and 3.27 for dual-stage burners.
Boiler installation requires connection to a 230 V - 50 Hz electric
mains: this connection must performed up to standard as
intended by current IEC regulations.
Danger!
Only a qualified technician may perform the
electrical installation.
Before performing connections or any type of
operation on electrical parts, always
disconnect electrical power and make sure
that it cannot be reconnected accidentally.
Remember that a bipolar switch must be installed on the boiler
power line with over 3 mm between contacts, easy to access,
making maintenance quick and safe.
The power cable must be replaced by authorised
technical personnel. Failure to comply with the
above can jeopardise the safety of the appliance.
