 How to enable or disable the filter
 For FR-F820-00105(2.2K) or higher and FR-F840-00023(0.75K) or higher
• 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.
• 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.)
