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 sup-
plied from the public low-voltage grid.
EMC device classification as per the rating plate or technical data.
In certain cases, even though a device complies with the standard limit values
for emissions, it may affect the application area for which it was designed (e.g.,
when there is sensitive 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.
Electrical installations must only be carried out according to relevant national
and local standards and regulations.
Danger of damage to electrical components from electrical discharge. Suitable
measures should be taken to protect against ESD when replacing and install-
ing components.
Only operate the device when all protection devices are fully functional. If the
protection devices are not fully functional, there is a risk of
-
injury or death to the operator or a third party,
- damage to the device and other material assets belonging to the operator,
- inefficient operation of the device
Any safety devices that are not functioning properly must be repaired by au-
thorized personnel before the device is switched on.
Never bypass or disable protection devices.
Devices with the CE marking satisfy the essential requirements of the low-volt-
age and electromagnetic compatibility directives. Further details can be found
in the appendix or the chapter entitled "Technical data" in your documentation.
