■ 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.
