EMC filter

This inverter is equipped with a built-in EMC filter (capacitive filter) and common mode choke.
The EMC filter is effective for reduction of air-propagated noise on the input side of the inverter.
The EMC filter is factory-set to enable (ON). To disable it, fit the EMC filter ON/OFF connector to the OFF position.
The input side common mode choke, built-in the FR-F740-01160 or less inverter, is always valid regardless of ON/OFF
of the EMC filter ON/OFF connector.

<How to disconnect the connector>
(1) 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 are no residual voltage
using a tester or the like. (For the front cover removal method, refer to page 5.)
(2) 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 long-nose pliers, etc.
