EMC Measures

In certain cases, even though a device complies with the standard limit values for emis-
sions, it may affect the application area for which it was designed (e.g., when there is sen-
sitive equipment at the same location, or if the site where the device is installed is close to
either radio or television receivers).
If this is the case, then the operating company is obliged to take appropriate action to rectify
the situation.
Check and evaluate possible problems and the interference immunity of equipment in the
vicinity according to national and international regulations:
-
-
-
-
Supporting measures to avoid EMC problems:
1.
2.
3.
4.
ensure that all covers are closed, and all side parts have been mounted properly
keep all covers closed
instruct them about all hazards (crush hazard posed by moving mechanical parts, in-
jury hazard from the cleaning cutter, flying chips or similar, discharged compressed
air/parting agent mixture, injury hazard due to flying sparks, blinding hazard due to
arcs, welding fume hazardous to health, noise exposure, possible hazard due to
mains current or welding current, etc.)
Provide suitable protective equipment, or
construct suitable protective walls and curtains.
Are only designed for use in industrial settings
Can cause line-bound and radiated interference in other areas
Satisfy the emissions criteria for residential and industrial areas. This is also true for
residential areas in which the energy is supplied from the public low-voltage grid.
Safety devices
Grid power lines, signal lines, and data transfer lines
EMC and telecommunications equipment
Devices for measuring and calibrating
Grid power supply
- If electromagnetic interference occurs despite a grid connection that complies
with regulations, take additional measures (e.g., use a suitable grid filter).
Control lines
- Keep them as short as possible
- Route them close together (also to avoid EMF problems)
- Route them far from other lines
Equipotential bonding
Shield, if necessary
- Shield other devices in the vicinity
- Shield the entire welding installation
