Converter Unit (Fr-Cc2) Built-In Emc Filter - Mitsubishi Electric FR-CC2-H355K Instruction Manual

Electro-magnetic interference (EMI) and leakage currents

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, connect two EMC filter ON/OFF female connectors to the ON male connectors. Two female
connectors are initially connected to the OFF (disabled) male connectors.
To enable the EMC filter, fit the both EMC filter ON/OFF connectors to the 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 tester or the
like.
• &&When disconnecting the female connector, pull the connector straight while pushing the tab. &&Do not pull the cable or
forcibly pulling the connector with the tab locked.
&&When connecting the connector, fit the connector securely until it clicks into place.
(If it is difficult to disconnect the connector, use a pair of needle-nose pliers, etc.)
