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 unsuita-
ble as earthing electrodes.
It is necessary to verify this fundamental safety requirement.
If in doubt, have the electric system carefully checked by pro-
fessionally 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 particu-
lar 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 agen-
ts (rain, sun, etc.) unless expressly designed;
• do not allow children or unskilled persons to use the ap-
pliance.
230V electric power supply connection
The electrical connections are illustrated in chap. 3.16, 3.17,
3.18, 3.19, 3.20.
The boiler installation requires a connection to a 230 V - 50
Hz electric mains: this connection must be properly carried
out as provided for 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 di-
sconnect 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 authori-
sed technical personnel. Failure to comply with
the above can jeopardise the safety of the ap-
pliance.
