Troubleshooting
Difficulty removing knockouts
Use appropriate tools designed for knockout removal. Ensure the correct knockout size is being targeted.
Water ingress detected
Check that all cable glands are correctly installed and sealed. Ensure the lid is properly closed and secured. Inspect the enclosure for any cracks or damage.
Terminals not gripping wires securely
Ensure conductors are stripped to the correct length and inserted fully into the terminals. Verify that the conductor size does not exceed the 50mm² limit.
Lid does not seal properly
Ensure no debris is present on the sealing surfaces. Verify the lid is correctly aligned before engaging the quarter-turn mechanism and screws.
