8.1.4 EMF assessments for 24 V components
The 24 V components, e.g. control systems (NCU, MCU, PPU), PCUs/IPCs, operator panels,
handheld terminals and machine control panels do not generate any appreciable
electromagnetic elds.
No minimum clearance has to be maintained for 24 V components.
8.1.5 SINUMERIK South Korea information
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 lter (EMC lter).
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 nal statement on compliance with the standard is given by the respective
label attached to the individual unit.
