EMC limit values in South Korea

The EMC limit values to be observed for South 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 according to EN 55011. With suitable 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 are
described in this Manual and/or the Configuration Manual "EMC Installation Guidelines".
Please note that the final statement on compliance with the standard is given by the
respective label attached to the individual unit.
