7. ELECTRICAL CONNECTIONS
The electrical connections must be made by specialist and qualified personnel, who are capable of
performing the work correctly and according to local standards. Before making the connections, ensure
that the machine is disconnected from the mains power.
Check that the voltage of the appliance's power supply corresponds to the value indicated on the data plate inside the electrical
panel . Introduce the power and ground connection cables into the electrical panel through the fairlead supplied, connect the
ends to the terminals and fasten them in place using the special tear-proof cable clamp (see Fig. 2.1). The power line to the
humidifier must be fitted with a cut-off switch and fuses protecting against short-circuits, to be mounted by the installer. Table
7.1.1 shows the recommended cross-sections of the power cable and the recommended sizes of the fuses; note, however, that
this data is purely indicative and, in the event of non-conformity with local standards, the latter must prevail.
7.1 Power supply voltages
Table 7.1.1 lists the electrical data regarding the power supply voltages of the various models and the functional characteristics
of each. Note that some models may be powered at different voltages, obviously with different consumption and steam
production values.

(1) Tolerance allowed on nominal mains voltage: ± 10 %.
(2) Tolerance on nominal values: +5%, -10% (EN 60335-1).
(5) Instantaneous steam production: the average steam production may be influenced by external factors, such as: ambient temperature, water quality, steam
distribution system.
