INSTALLATION
2-4 ELECTRICAL CONNECTION AND EARTHING
The electrical connection and the tests listed below must always be carried out by a specialised electrician.
Ensure that the electric line of the factory is sufficient to support the power of the machine and check that the mains voltage
corresponds to that of the machine.
Note: The ideal operating condition for the machine is to supply the exact voltage shown on the identification
plate in Fig. 2.2; (tolerance ± 5%).
Out of this range, adjust the power supply voltage.
On the machine identification plate, read the value of the total absorbed current (Amp).
Then, referring to the table below select the cable cross-sections, and the fuses to install upstream of the
machine. The fuses are of the “DELAYED FUSE” (AM) type.

Electrically isolate the machine by setting the main switch to zero and connect the 3 electrical cables (phases)
to the terminals L1, L2, L3 as in Fig. 2.2.
Connect the yellow-green cable (earth) to the terminal (PE) or marked with the symbol , and the neutral cable,
if present, to the terminal (N).
Should the machine be connected to a mobile power cable, use a flexible rubber cable marked with the symbols
H07RN-F or A07RN-F has to be in accordance safety current standards of the country in wich it will be used.
The relevant coupling outlet must comply with the DIN 49463 regulation and the international regulations
IEC309-1 and IEC309-2 or to safety current standards of the country in wich it will be used.
Carefully lock the cable clamp (G Fig. 2.2). Check that the spindle rotation direction is correct (the spindles must
rotate in the opposite direction to the piece feed) by starting the machine as described further on.
If the spindles do not turn in the right direction:
- Disconnect the power
- Invert two phases on the terminal board
- Retest the rotation direction.
Warning!!!: In normal operating and maintenance conditions, the door of the electric box must always remain
closed. It may only be opened by a specialised electrician using the special key provided with the
machine and kept by the expert operator.
The complete wiring diagrams and certificates may be found in the accessory bag.
