7. Install Strain-relief Hardware in Express Port
Refer to SRP 206-288 (Heat-shrink End Cap Canister Closure Sealing Checklist) to ensure all critical steps for
sealing the closure have been performed accurately.
Step 1: Wrap a large hose clamp around the bracket and cable approximately 6 mm (0.25 inches) below the
sheath opening (Figure 8) .
Step 2: Position the hose clamp with the tensioning body on the same side of the bracket as the threaded
stud.
Step 3: Tighten the hose clamp in the notch on the bracket.
NOTE: Make sure the tensioning body on the hose clamp is positioned as shown.
Step 4: Secure the assembly to the end cap using the provided screw (Figure 9) .
8. Install Cable
CAUTION: Use sealing paste and cable cleaner in a well-ventilated area to eliminate the possibility of
dizziness and nausea. If paste or cleaner comes in contact with skin or eyes, wash area immediately
with soap and water to avoid irritation. Do not induce vomiting if paste or cleaner is ingested.
IMPORTANT: Torches are not recommended for the application of the heat-shrink tubes included with this kit.
Certain combinations of cable sheath materials and torches may cause sheath blistering. To avoid
sheath damage, aluminum tape (2.5-in width) can be applided cylindrically around the cable
sheath (Figure 10) . The cable must be cleaned and roughened before installing the tape. Center
the tape over the mark made in Section 6 . Press the tape smooth at the edges to prevent possible
pathways for water intrusion.
Step 1: Clean and roughen the cable approximately 75
or 100 mm (3 or 4 inches) towards the end of the
cable using the supplied sandpaper.
Step 2: Roughen the appropriate cable port to ensure
heat-shrink adhesion.
Step 3: Carefully preheat the port and cable with the heat
gun.
Step 4: Slide the heat-shrink tube over the port until it
butts against the end cap.
Step 5: Pull the cable(s) back through the port.
