Built-In Emc Filter - Mitsubishi Electric FR-F820-04750 Instruction Manual

Precautions for use of the inverter
3.1.3

Built-in EMC filter

This inverter is equipped with a built-in EMC filter (capacitive filter) and a common mode choke. Those
filters are effective in reducing air-propagated noise on the input side of the inverter.
To enable the EMC filter, fit the EMC filter ON/OFF connector to the ON position. The FM type is initially
set to "disabled" (OFF), and the CA type to "enabled" (ON).
The input side common mode choke, which is built in the FR-F820-02330(55K) or lower and FR-F840-
01160(55K) or lower inverter, is always enabled regardless of the EMC filter ON/OFF connector setting.
