  4. CHECK CONNECTOR CONNECTION CONDITION (INVERTER WITH CONVERTER ASSEMBLY CONNECTOR) 
    WARNING:

    Be sure to wear insulated gloves.

    1. Check that the service plug grip is not installed.
      NOTE:

      After removing the service plug grip, do not turn the power switch on (READY), unless otherwise instructed because this may cause a malfunction.

    2. Check the connector connections and contact pressure of the low voltage connectors of the inverter with converter assembly (Refer to ELECTRONIC CIRCUIT INSPECTION PROCEDURE [10/2014 - ] ).
      NOTE:

      Before disconnecting the connector, confirm that it is properly connected by checking that the locking claws are engaged and that the connector does not pull out.

      OK

      The connectors are connected securely and there are no contact pressure problems.

      HINT: 

      When connecting the connector, insert it with the locking lever in the raised position. Rotate the lever downward and make sure that the connector is pulled into its socket. When the locking lever is in its fully closed position, a click will be heard as its locking claws engage. After the click is heard, pull up on the connector to confirm that it is properly connected.
