Electrical connections
Make sure that the power outlet is appropriate before connecting the power cable. Check the information on the plate located on the back of
the machine for more information.
Make sure that the electrical outlet of the mains supply has a Schuko socket; the welder absorbs 10A at 230Vac for the L0T00F11 and
L0T0F11N models, and 16A for the L0T00F12 and L0T0F12N models.
Install a general duty safety switch upstream of the device's cable connection with the power grid.
The safety switch should be used in combination with a surge protection device equipped with an emergency shut-off switch (SPD).
The features of these devices should be designed to meet the regulations of the country where the device is being installed, and
sized according to the specifications of the device.
Power supply tolerances
Voltage at
10% of the rated voltage.
Frequency:
1% of the rated voltage for continuous use
2% of the rated voltage for short periods
Harmonic distortion for the sum of the second to fifth harmonics no more than 10% of the total voltage RMS between live
conductors. Further distortion is permitted for the sum of the sixth to thirtieth harmonics up to 2% on the total RMS between live
conductors.
The voltage pulses should be no longer than 1.5 ms with a rise/fall time of between 500ms and
500μs
and a peak value that does not
exceed 200% of the effective value of the nominal supply voltage.
The power supply should not be interrupted nor go to zero for longer than 3ms at any moment during power. There should be no
more than 1s between two successive interruptions
The voltage dips should not exceed 20% of the peak voltage for more than one cycle. There should be no more than 1s between
voltage dips.
