9.1.2 Measures 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.
* Dimensions of EMI filter : See 10.4 (Page J-11)
