The housing screws provide an adequate ground conductor connection for earth-
ing the housing. The screws must never be replaced with different screws unless
a reliable ground conductor connection is set up.
EMC Device
Classifications
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 Warning, electromagnetic field. Electromagnetic fields may pose as yet unknown
risks to health.
It is the operator's responsibility to ensure that no electromagnetic interference
occurs in electrical and electronic devices.
If electromagnetic interference is detected, the operator is obliged to take action
to rectify the situation.
Check for possible problems, and check and evaluate neighbouring devices' res-
istance to interference according to national and international requirements:
-
Safety devices
-
Power, signal and data transfer lines
-
IT and telecommunications devices
-
Measuring and calibrating devices
-
Health of neighbouring persons
Supporting measures for avoidance of EMC problems:
1.
Mains supply
-
If electromagnetic interference arises despite the correct mains connec-
tion, additional measures are necessary (e.g. use of a suitable line filter)
2.
Shielding, if necessary
-
Shield off other nearby devices
-
Shield off entire welding installation
3.
Do not have any magnetic or electronic data carriers about your person:
magnetic or electronic data carriers can be damaged by the magnetic fields
generated when the device is in use.
4.
Do not have any watches or pieces of metal about your person. Watches can
be damaged when the device is in use.
Safety measures
at the installa-
tion location and
during transport
A device toppling over could easily kill someone. Place the device on a solid, level
surface such that it remains stable
-
The maximum permissible tilt angle is 10°.
Special regulations apply in rooms at risk of fire or explosion
-
Observe relevant national and international regulations.
Use internal work instructions and checks to ensure that the workplace environ-
ment is always clean and clearly laid out.
Only set up and operate the device in accordance with the degree of protection
shown on the rating plate.
