9.1.2Measures to satisfy the EMC directive
This subsection explains what measures must be taken to satisfy the EMC directive.
(1)Insert a recommended EMI filter (Table 2) on the input side of the inverter to reduce radiation and transmis- sion noises. In the combinations listed in Table 2, inverters were checked for conformity with the EMC di- rective. For inverters used in Japan, it is recommended to use the NF series of noise filters.
Table 2 lists noise filters recommended for the inverters.
