EMC limit values in South Korea
The EMC limit values to be complied with for South Korea correspond to the limit values of
the EMC product standard for variable-speed electric drives EN 61800-3, Category C2, or
limit value class A, Group 1 according to EN 55011. By applying suitable supplementary
measures, the limit values according to Category C2 or according to limit value class A,
Group 1, are maintained. Further, additional measures may be required, for instance, using
an additional radio interference suppression filter (EMC filter).
The measures for EMC-compliant design of the system are described in detail in this manual
respectively in the Installation Guideline EMC.
Please note that the final statement on compliance with the standard is given by the
respective label attached to the individual unit.
