6.8.2 Power supply
The electrical wiring to the terminal blocks has to be done only by qualified personnel.
Make sure to install an adequate ground connection, incomplete grounding can cause electric shock. The
manufacturer cannot be held responsible for any damage caused by failure or ineffective earthing.
Power cables, electric protections and line fuses must be sized according to the specifications listed in the wiring diagram enclosed
with the unit and in the electrical data contained in the table of technical characteristics (see Paragraph 0).
Use a dedicated power line, do not power the appliance through a line to which other users are connected. Fasten the power
cables securely and make sure they do not come into contact with sharp corners. Use double insulated cables with copper wires.
Details on the type and nominal specifications of the fuses are set out on the machine’s data plate, as well as on the fuses.
The earth connection must be carried out first during the connection phase, in another way it must be removed last when the unit
is disconnected. In the event of any loosening of the power cable, it must be ensured that the voltage of the active conductors
takes place before that of the earth wire.
A main switch or a disconnection device with adequate breaking capacity must be installed on the power supply line, which has a
separation of the contacts in all the poles. The earth leakage breaker must be compatible with inverter appliances, it is
recommended to install a type B differential switch, the installation of a different type switch could give rise to untimely trips.
The following table shows the recommended cable sections for a maximum length of 30 m. In any case, depending on the type of
installation, the physical location and the length of the cables (whether less than or greater than 30m), the designer of the
electrical system will make an appropriate choice.

The units comply with the electromagnetic compatibility specifications, the designer of the electrical system must however make
the appropriate assessments to ensure the absence of interference.
6.8.3 Connection terminal block
The connection terminal block is below the cover of the machine. To reach it, see the instructions in paragraph 5.8.1. The terminal
block must be connected according to the following notes.
The connections indicated below are standard. Other connections are shown in the User interface instruction manual, depending
on the configurations adopted.
The electrical wiring to the terminal blocks has to be done only by qualified personnel.
It is important to keep the high voltage cables separate from the very low voltage ones
