3.1.3
Built-in EMC filter
The converter unit (FR-CC2) is equipped with a built-in EMC filter (capacitive filter).
These filters are effective in reducing air-propagated noise on the input side of the converter unit.
Two female connectors are initially connected to the OFF (disabled) male connectors.
To enable the EMC filter, fit both of the EMC filter ON/OFF connectors to the "enabled" (ON) position.
