Before you start stripping the cable jacket, take the time to carefully measure and mark the correct length. This will prevent you from stripping too much or too little of the jacket, which can affect the integrity of the seal. Use a sharp utility knife or cable stripping tool to make a clean cut around the jacket, being careful not to damage the conductors or shielding underneath. After stripping the jacket, inspect the conductors for any signs of damage, such as nicks, cuts, or abrasions. If you find any damage, repair it before proceeding with the installation. A damaged conductor can compromise the performance of the cable and potentially create a safety hazard.

Step 2: Selecting the Right Sealing Modules

Roxtec's modular system means you have to choose the right sealing modules. Measure the outer diameter of your cables using calipers. Use Roxtec's selection guide to pick the appropriate modules for your cable sizes. Each module has removable layers, so you can adjust the fit precisely. Getting the right fit is essential for a proper seal. If the module is too large, the seal will be loose and ineffective. If it's too small, you won't be able to insert the cable. Take your time and double-check your measurements to ensure you select the correct modules.

When selecting the sealing modules, consider not only the cable diameter but also the cable type and material. Different cable types may require different types of sealing modules to achieve the best seal. For example, armored cables may require modules with additional support or protection to prevent damage to the armor. Similarly, cables made of different materials may have different expansion and contraction rates, which can affect the seal over time. Roxtec's selection guide provides detailed information on the compatibility of different sealing modules with various cable types and materials. Consulting this guide will help you make the right choice and ensure a long-lasting, reliable seal.

Step 3: Installing the Gland Body

Now, install the gland body into the structure, whether it's a wall, enclosure, or equipment housing. Make sure the surface is clean and free of any debris. Use the appropriate mounting hardware to secure the gland body in place. Tighten the hardware to the manufacturer's specified torque to ensure a secure and watertight connection. Proper installation of the gland body is critical for the overall performance of the Roxtec system. A loose or improperly installed gland body can compromise the seal and allow water, dust, or other contaminants to enter the enclosure.

Before installing the gland body, inspect it for any signs of damage, such as cracks, dents, or corrosion. If you find any damage, replace the gland body before proceeding with the installation. Use a level to ensure that the gland body is installed straight and plumb. This will prevent stress on the cables and sealing modules, which can lead to premature failure. Apply a thin layer of sealant to the mating surface between the gland body and the structure to create a watertight seal. The type of sealant you use will depend on the materials of the gland body and the structure. Consult Roxtec's documentation for recommendations.

Step 4: Inserting the Sealing Modules

With the gland body in place, it's time to insert the sealing modules around the cables. Apply a small amount of Roxtec lubricant to the modules to make them easier to insert. Insert the modules one by one, ensuring they fit snugly around the cables. Use the Roxtec insertion tool to push the modules fully into the gland body. The insertion tool helps you apply even pressure, ensuring that the modules are properly seated. Proper insertion of the sealing modules is essential for achieving a reliable seal. If the modules are not fully seated, there may be gaps or voids that allow water or dust to enter the enclosure.

When inserting the sealing modules, pay attention to the orientation of the modules. Some modules have a specific orientation that must be followed to ensure proper sealing. Roxtec's documentation provides detailed instructions on the correct orientation of each module. Use a visual inspection to verify that the modules are fully seated and there are no gaps or voids. If you find any gaps, remove the modules and re-insert them, making sure to apply even pressure and use the Roxtec insertion tool.

Step 5: Compression and Tightening

After all the modules are in place, compress the gland to create the seal. Tighten the compression unit to the torque specified by Roxtec. Use a torque wrench to ensure you don't over-tighten or under-tighten the gland. Over-tightening can damage the sealing modules or the cables, while under-tightening can result in a loose seal. Proper torque is crucial for achieving a reliable and long-lasting seal. Once the compression unit is tightened, inspect the gland to ensure that all the modules are compressed evenly and there are no gaps or voids.

Before tightening the compression unit, make sure that the cables are properly positioned and there is no tension on them. Tension on the cables can affect the seal and potentially damage the cables over time. Use a cable tie or other means to secure the cables in place and prevent them from moving during the tightening process. After tightening the compression unit, wait a few minutes and then re-torque the gland to ensure that the seal has settled properly. This will help to compensate for any relaxation of the materials and ensure a consistent seal.

Step 6: Final Inspection

Finally, give the installation a thorough inspection. Check that all the sealing modules are correctly positioned and fully compressed. Ensure that the gland is properly tightened to the specified torque. Look for any signs of damage or gaps that could compromise the seal. If everything looks good, you're done! A final inspection is crucial for identifying any potential problems and ensuring that the installation is done correctly.
