4. CONNECTION TO THE LINE OF USER
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 trough the
equipped cable as follows:
- yellow-green cable to earth;
- Remaining 3 cables to the 3 phases.
Connect to the input cable a certified plug with the correct capaci-
ty, predispose a net socket with safety fuses or with an automatic
safety switch OFF. Make sure that the earth cable is securely con-
nected to the earth conductor (YELLOW-GREEN) of the input net
line.
NOTE:
if input cable extensions are needed, make sure to use the
correct size, which does not have to be smaller then the one that
the machine is equipped with.
