Roxtec CF 8/32 EMC Cable Transit Frames

Sealing Cables & Cable Ducts

Roxtec CF 8/32 EMC cable transit frames are constructed from cast aluminium with nickel plating to ensure electrical conductivity – the Roxtec frame is suitable for installation also around existing multiple or single pre-terminated cables and pipes in one opening.

Roxtec rectangular cable transit frames are used to provide a reliable cable sealing ensuring safety, efficiency and long-term operational reliability – Roxtec cable seals protect against fire, gas, water, dusts, pests, blast load and electromagnetic interference.

Installing Roxtec CF 8/32 EMC Cable Transit Frames

Contact T&D should you require support on the installation of Roxtec CF 8/32 EMC cable transit frames:

Frame Installation

Roxtec CF 8/32 EMC Cable Transit Frame

  • 1. Ensure good electrical conductivity between the counter frame and the structure. Clean the surface around the opening from inside the opening. Remove any paint if necessary.
  • 2. Insert the frame from the outside of the opening.
  • 3. Insert the counter frame from the inside of the opening.
  • 4a. Fasten the frame by tightening the special nuts with an allen key.

  • 5. Insert all the cables.
  • 6. Mark where the outer sheath is to be removed to fit the tape position.
  • 7. Remove the outer sheath to uncover the conductive surface. Remove any protection tape or plastic.
  • 8. Lubricate the frame corners and areas that will be in contact with the rubber of the modules. Do not lubricate the areas that will be in contact with the tape.

Module Installation

  • 1. Insert the modules around the cables from the inside of the cabinet.
  • Cable and module position in the frame. Cable shall be installed so that exposed cable screen runs into the cabinet.
  • 2a. ES. Lubricate sparsely the front rubber area of the C Compression unit ES on all sides. Avoid lubricant on the conductive rubber. This is important for maintaining the EMC performance of the seal.

  • 2b. PE. Lubricate the C Compression IP/NEMA sparsely on all sides.
  • 3. Gently insert the compression unit.
  • 4. Tighten the compression unit to seal the frame. Recommended torque 8-12 Nm.

CM ES

  • 1. Remove the protection paper from the modules and fold back the tape.
  • 2a. Adapt outer layers to cable. (Fig 11:A)
  • 2b. Adapt inner layers to cable screen. (Fig 11:B)
  • 2c. Adapt vertical screen to cable screen. (Fig 11:C)

  • 3. Test with a cable. Achieve a gap of 0.1-1.0 mm between the module halves. If not, repeat 2a-c. The halves may not differ by more than one layer. Make sure the screen is in good contact with the module.

CM PE

  • 1. Remove the protection paper from the modules and fold back the tape.
  • 2a. Adapt outer layers to cable. (Fig 13:A)
  • 2b. Adapt inner layers to cable screen. (Fig 13:B)
  • 3. Test with a cable. Achieve a gap of 0.1-1.0 mm between the module halves. If not, repeat 2a-b. The halves may not differ by more than one layer. Make sure the screen is in good contact with the module.

  • 1a. Fold the adhesive tape tightly inside the module half from one side along the inner layers.
  • 1b. Lift the plastic film from the folded side.
  • 1c. Fold the tape on the other side tightly inside the module half. There must be no air-pockets.
  • 1d. Fold the plastic film back inside the module half.

  • 2. Lubricate all modules sparsely with Roxtec Lubricant on inside and outside rubber surfaces only. Do not lubricate the film.
  • 3. Remove the plastic film. Keep the tape clean. Note: Plastic must be removed on spares also.
  • 4. Continue to installation instructions for your frame.
