7. INSTALLATION
7.1 Connection of the line of user
Warning! These operations must be performed by personnel with
sufficient professional knowledge on the electrical part and the global
knowledge on safety. Operators must have valid qualification
certificates that can demonstrate their professionalism and knowledge
on the matter.
Before connecting the system to the net, check that the input voltage (V) and
work frequency (Hz) correspond to the values that are printed on the
machine serial number sticker and make sure that the main switch is on the
“0” position.
The electrical connection to the net can be operated through the equipped cable as follows:
- yellow-green cable to earth;
- the remaining wires to the net.
Connect a certified plug with the correct capacity to the input cable, predispose a net socket
with safety fuses or an automatic safety switch OFF. Ensure that the earth cable is securely
connected to the input net line’s earth conductor (YELLOW-GREEN). Note: if input cable
extensions are needed, make sure to use the correct size, which does not have to be smaller
than the one that the machine is equipped with.
