•
The dimensions of the work area to consider will depend on the construction of the area and other activities that are
taking place.
Consider the following guidelines to reduce electromagnetic emissions from the machine.
•
Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take
additional precautions such as filtering the input supply.
•
The output cables should be kept as short as possible and should be positioned together. If possible connect the
work piece to ground in order to reduce the electromagnetic emissions. The operator must check that connecting
the work piece to ground does not cause problems or unsafe operating conditions for personnel and equipment.
•
Shielding of cables in the work area can reduce electromagnetic emissions. This may be necessary for special
applications.
WARNING
The Class A equipment is not intended for use in residential locations where the electrical power is provided by the public
low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility in those
locations, due to conducted as well as radiated disturbances.
WARNING
This equipment complies with IEC 61000-3-12 provided that the short-circuit power S
sc
is greater than or equal to:
POWERTEC 305C PRO:
S
sc
≥
1,9MVA
POWERTEC 355C PRO:
S
sc
≥
2,2MVA
POWERTEC 425C PRO:
S
sc
≥
2,9MVA
at the interface point between the user’s supply and the public system. It is the responsibility of the installer or user of
the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is
connected only to a supply with a short circuit power S
sc
greater than or equal to data on the table above.
