2.1.2 EMC filter
This inverter is equipped with a built-in EMC filter (capacitive filter) and zero-phase reactor.
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 zero-phase reactor, built-in the 01800 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. (
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.)
CAUTION
⋅
Fit the connector to either ON or OFF.
WARNING
While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.
