Inserting a cable into the vertical mount contact connector
1
When installing the cable, check the locking actuator to verify it is in the open position.
2
Insert the cable with the contacts on the cable away from the locking actuator. Insert the cable on top of the actuator.
Note: Verify that the cable is installed squarely into the connector. If the cable is not squarely installed, then
intermittent failures could occur.
