Converter unit (FR-CC2) 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.
To enable the EMC filter, set the EMC filter ON/OFF connector to the ON position.
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.
 How to enable or disable the filter
• Before removing a front cover, check to make sure that the indication of the inverter operation panel is OFF, wait for at
least 10 minutes after the power supply has been switched OFF, and check that there is no residual voltage using a digital
multimeter or the like.
• When disconnecting the connector, push the fixing tab and pull the connector straight without pulling the cable or forcibly
pulling the connector with the tab fixed.
When installing the connector, also engage the fixing tab securely.
(If it is difficult to disconnect the connector, use a pair of needle-nose pliers, etc.)
