6.1.2Measures to satisfy the EMC directive

6

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 and transmission noise and radiation noise from input cables.

In the combinations listed in Table 2, Inverters are tested in these combination to see if they comply with transmission noise standards. 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.
