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.
These 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 EMC filter is initially set to the "disabled"
(OFF) position for the FM type (with a built-in C3 filter). The EMC filter is initially set to the "enabled" (ON) position for the FM
type (with a built-in C2 filter) and the CA type.
The input side common mode choke, which is built in the inverter, is always enabled regardless of the EMC filter ON/OFF
connector setting.
