■ When an external EMC filter is added
(1) Additional external EMC filters have the further effect of suppressing conduction and radiation noises. Use the
recommended EMC noise filter specified in Table 3. This combination of inverter and filter was used when
examining the inverter for compliance with the EMC directive.
Table 3 lists noise filters recommended for the inverters.
