• Switching ON/OFF the filter
(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 is no residual voltage using a
tester or the like.
(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 needle-nose pliers, etc.)

NOTE
• Do not change the initially set ON (enabled) position of the EMC filter ON/OFF connector when a built-in C2 filter is used. The
Class C2 compatibility condition is not satisfied with the EMC filter OFF.
• The FR-A846-00250(7.5K)-C2 to FR-A846-00470(18.5K)-C2 are not provided with the EMC filter ON/OFF connector. The
EMC filter is always ON.
• Fit the connector to either ON or OFF position.
• Enabling (turning ON) the EMC filter increases leakage current. (Refer to
WARNING
 While power is ON or when the inverter is running, do not open the front cover. Otherwise you may
get an electric shock.
