z EMC Device Classification
According to the standard IEC 60974-10, this is a welder in elec-
tromagnetic compatibility Class A. Class A devices are devices that
are suitable for use in all other areas except living areas and areas
that are directly connected to a low-voltage supply mains that (also)
supplies residential buildings. Class A devices must adhere to the
Class A limit values.
WARNING NOTICE: Class A devices are intended for use in
an industrial environment. Due to the power-related as well as the
radiated interference variables, difficulties might arise in ensuring
electromagnetic compatibility in other environments.
Even if the device complies with the emission limit values in accord-
ance with the standard, such devices can still cause electromagnetic
interference in sensitive systems and devices. The user is responsible
for faults caused by the arc while working, and the user must take
suitable protective measures. In doing so, the user must consider the
following:
power cables, control, signal and telecommunication lines
–
computer and other microprocessor controlled devices
–
television, radio and other playback devices
–
electronic and electrical safety equipment
–
persons with cardiac pacemakers or hearing aids
–
measurement and calibration devices
–
noise immunity of other devices in the vicinity
–
the time of day at which the work is being done.
–
The following is recommended to reduce possible interference
radiation:
fit a mains filter to the mains connection
–
service the device regularly and keep it in good condition
–
welding cables should be completely unwound and installed
–
parallel on the floor, if possible
if possible, devices and systems at risk from interference radiation
–
should be removed from the work area or shielded.
Note!
This device complies with IEC 61000-3-12, provided that the Ssc
short circuit power is larger or equal to 6106.5 kW at the interface
point between the operator's supply and the public supply. It is the
responsibility of the installer or user of the device, after consultation
with the distribution system operator if necessary, to make sure that
