Troubleshooting

Enclosure lid does not seal properly

Ensure the seal is clean and free from debris. Check for any obstructions on the mating surfaces of the lid and enclosure body. Ensure the lid is fully closed and latched securely.

Cable cannot be securely fastened in a DMS connector

Verify that the cable's outer diameter falls within the specified sealing range for the DMS connector being used. If the cable is too thin, it may not be gripped effectively. Consider using a different size connector or an adapter if available.

Water ingress into the enclosure

Inspect all cable entries (DMS connectors and M50 nipples) for proper sealing. Check the condition of the seals and tighten the connectors if necessary. Ensure the enclosure lid is fully closed and the seal is intact.

Difficulty mounting components on the NS 35 rail

Ensure the NS 35 rail is correctly installed and aligned. Check that the components being mounted are compatible with the NS 35 rail standard.

  2. Route electrical cables through the appropriate DMS connectors or M50 twisting nipples. Ensure the cable diameter falls within the specified sealing range for the chosen connector.
  3. Secure the cables within the DMS connectors by tightening them onto the cable sheath to maintain the enclosure's sealing.
  4. Mount the enclosure to a suitable surface using appropriate fixings, ensuring it is stable and securely positioned.
  5. Install terminal blocks or other components onto the NS 35 rail inside the enclosure.
  6. Make electrical connections, ensuring all connections are tight and properly insulated.
  7. Close and secure the enclosure lid, ensuring a tight seal.

Care:

  • Clean the exterior of the enclosure with a damp cloth. Avoid using abrasive cleaners or solvents that could damage the plastic.
