1. DESCRIZIONE DEI COMPONENTI
GB GB
Make sure that the general power supply has been turned off. Never touch
the electrical components immediately after removing the power supply,
always wait at least 5 minutes .
• The electrical connections must be carried out by qualified personnel and in
compliance with the regulations in force in the place of installation
• The connection must be preceded by an accurate check of compatibility
between the power supply line and the characteristics to be connected.
• The unit must be connected to an impedance electrical network

• The heat pump power cables must have a section equal to or greater
than that indicated in the following table.
• The power cord must comply with the IEC standard. (60245 IEC57
(H05RN-F)
• In the power supply line of the unit it is mandatory to provide a differ-
ential / magnetothermal switch with a contact separation of at least
3 mm in each pole, with a maximum trip threshold of 30 mA, sized
according to the table:
