EMC limit values in South Korea
The EMC limit values to be observed for Korea correspond to the limit values of the EMC
product standard for variable-speed electric drives EN 61800-3 of category C2 or the limit value
class A, Group 1 to KN11.
By implementing appropriate additional measures, the limit values according to category C2
or limit value class A, Group 1, are observed.
Additional measures, such as the use of an additional RFI suppression filter (EMC filter), may
be necessary.
In addition, measures for EMC-compliant configuration of the plant or system are described
in detail in this manual and in the Configuration manualEMC installation guideline (
support.automation.siemens.com/WW/view/en/60612658
The final statement on compliance with the applicable standard is given by the respective label
attached to the individual device.
