3. Electrical supply
The machine is designed for the following nominal voltages:
Nominal voltage Frequency
400 V ± 10 % 50 Hz ± 1 %
460 V + 10 %/– 5 % 60 Hz ± 1 %
If the available nominal voltage varies from the nominal voltage
specified above (400 V or 460 V), an isolating transformer must be
installed.

The electrical power supply of the system requires a 4-pole
connection with copper cable (L1, L2, L3 in the right rotary field; PE).
The main power supply is usually connected at the laser control
cabinet. The symbol on the left marks the connection point in the
installation plan.

If the rated voltage is 380 V or 415 V at 50 Hz, the tolerance of the network
must be determined. If the tolerance is found to be between 360 V – 440 V,
an isolating transformer is not necessary.
