Installation

Attaching the Fiber Cable Clasp to the Cable

Aligning the Key

and Locking

Ring

The key to installing the cable is to align the barrel, the locking ring and the connector, as shown in the diagram below.

The table below shows how to align the key and locking ring.

Step

Action

1Turn the locking ring to align an arrow with the key.

2Then align the key with the keyway. As a result, the locking tab, groove and lock should also be aligned.

3Slide the clasp up to the locking ring.

4Gripping the cable with the clasp, plug the cable into the lower (receive) cable connector. If it does not connect easily, realign the key with the arrow and try again.
