Chapter 7 Optional Accessories MS300 (IP66 / NEMA 4X)
7-20
7-6 EMC Filter (IP Level: IP20)
Using an EMC filter enhances the machine and surrounding environment's EMC capabilities to
meet with EMC requirements and reduces problems caused by EMC. If you use a model without
a built-in EMC filter, it is recommended that you buy an optional EMC filter. Some models may
need to work with zero phrase reactors to comply with EMC standards. The table and figure
below show the recommended models for EMC filters and zero phase reactors, installation
methods, and the maximum motor cable length.
