Estimated time: 4h
Tools needed:
Hacksaw, Strap wrenches, Wire strippers, Multimeter, Damp cloth
Supplies needed:
SC4-KIT-1 LIQUID SEALANT (6 units), Fiber damming material, Lubricant, Gloves and other PPE
- De-energize Circuits and Prepare Workspace
WARNING: Before beginning installation or performing maintenance, verify that all circuits are de-energized to prevent the risk of electrical shock. Ensure a qualified electrician performs the installation in accordance with national and local electrical codes. Gather all required tools and supplies.
- Prepare Cable Armor and Jacket
Determine the required working length of conductors inside the enclosure. Remove a portion of the outer jacket to expose the cable armor. Carefully cut the armor using a hacksaw, taking caution not to nick or cut the conductor insulation. Trim the outer jacket to the appropriate strip length as indicated in the product table for your specific cable type (refer to the document's table for STX300-479PVC).
- Prepare and Position Cable Boot
Choose a method to cut the cable boot: Method 1 involves unscrewing the gland nut, forcing the square-cut cable into the boot, and cutting the boot in front of the cable. Method 2 involves stripping the cable jacket off the armor and progressively cutting slices off the boot until it snugly slides onto the armor. Apply lubricant where indicated before screwing the gland nut. Feed the cable through the gland nut opening and push until the cable armor firmly hits the end stop.
- Tighten Gland Nut and Disassemble Fitting
Tighten the gland nut until an appropriate seal is obtained, or to the maximum torque specified in the product table for STX300-479PVC. Ensure the bushing seals evenly around the cable's outer jacket and the cable remains centered for an optimal seal. Next, disassemble the hub from the body sub-assembly by loosening the union, then unscrew the sealing chamber from the body sub-assembly.
- Prepare Conductors and Pack Damming Material
Trim the inner jacket to a length of 1/8 to 3/8 inches to expose the conductor bundle. If working with shielded data cables, refer to Section 2 of the original document for additional steps to remove shields and filler materials. Pack the fiber damming material tightly into all voids between the conductors and the body. Spread the strands of any uninsulated grounding conductor, if applicable.
- Apply Liquid Sealing Compound (SC4-KIT-1)
Screw the sealing chamber back onto the body sub-assembly until it completely seats. Position the cable and fitting vertically. Mix the SC4-KIT-1 liquid sealing compound according to its package instructions. For STX300-479PVC, fill approximately HALF of the sealing chamber. Wait 2 hours for this portion to set, then fill the remaining half of the sealing chamber to the top. CAUTION: Wear gloves and other proper PPE. Remove all excess compound from the outside of the sealing chamber with a damp cloth; do not use abrasive cleaners.
- Mount Hub and Secure Assembly
Mount the hub in the desired location. After the sealing compound has solidified (approximately 1 hour after the final pour), place the encapsulated assembly into the hub. Secure it in position by tightening the union until it bottoms out, ensuring metal-to-metal contact.
