5.9.1 Access to electric panel
The following is the procedure for accessing the electric panel.
A
1.
Remove the two access panels to the components compartment by unscrewing the screws as shown in figure 1
2. To access the power supply terminal block, remove panel A by unscrewing the screws as shown in figure 2.
3. To access the user terminal block, remove panel B by unscrewing the screws as shown in figure 2. 4.
Insert the cables in the grommets provided on the rear side of the machine to connect them to the system.
5.
Close the electrical panel and the access panels to the machine components compartment using the screws previously removed.
The above-mentioned operations must be carried out with the machine off and power disconnected (by means of the specif-
ic disconnector applied by the installer).
Operations carried out by qualified personnel.
When the work is finished, close all of the removed covers applying the screws and gaskets (if included).
5.9.2 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..
The power cables, electrical protections and line fuses must be sized in accordance with what is reported in the unit's wiring diagram and in the
electrical data contained in the technical characteristics table.
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.
The ground connection must be carried out first during the connection phase, vice versa 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 tension of the active conductors takes place before that of the
ground 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 differential protection switch 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 type of installation, the
location and the length of the cables (be it less than or greater than 30 m), the electrical system designer will make an appropriate choice..
