Step 5 - Optex Fiber SenSys Terrain Defender TD 100 Installation Manual

Remove one of the two seven-entry silicon grommets provided in the SUMA kit. Pull the
sensor cable through the large center hole from the outside of the grommet, which does not
have the markings for cable sizing, through to the inside of the grommet, which has sizing
information.
Next, pull the lead-in cable with terminated SMA connector through one of the six smaller
holes in the grommet, it's best to place this toward the SUMs female SMA connector side.
Lastly, pull the ≥18AWG 2-conductor power cable and ≥12AWG ground wire, 3.175 mm
(.125 in) or larger cable diameter each, through two of the remaining smaller holes to
provide DC power to the SUM and grounding. Insert grommet plugs in the unused entry
holes.

Pull a little extra sensor cable through to providing room for the following steps on cable
preparation. The sensor cable, or any of the cables, can be pulled back for fitment when the
SUMs are placed inside the enclosure

Step 5

Remove the second of the two seven-entry silicon grommets, and repeat the process from
