EMC Device Clas-
sifications
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- 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 mains.
EMC device classification as per the rating plate or technical data.
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 operator is obliged to take appropriate action to rectify the situ-
ation.
Check for possible problems, and check and evaluate neighbouring devices' resistance to
interference according to national and international requirements:
- Safety devices
- Power, signal and data transfer lines
- IT and telecommunications devices
- Measuring and calibrating devices
Supporting measures for avoidance of EMC problems:
1. Mains supply
- If electromagnetic interference arises despite correct mains connection, addition-
al measures are necessary (e.g. use a suitable line filter).
2. Control lines
- must be kept as short as possible
- must run close together (to avoid EMF problems)
- must be kept well apart from other leads
3. Equipotential bonding
4. Shield, if necessary
- Shield off other nearby devices
- Shield off entire welding installation

12
EMF measures Electromagnetic fields may pose as yet unknown risks to health:
- effects on the health of others in the vicinity, e.g. wearers of pacemakers and hearing
aids
- wearers of pacemakers must seek advice from their doctor before approaching the de-
vice or any welding that is in progress
- for safety reasons, keep distances between the welding cables and the welder's head/
torso as large as possible
- do not carry welding cables and hosepacks over the shoulders or wind them around
any part of the body
Safety measures
