Troubleshooting
Terminal overheating
Check for loose connections, ensure wire size is within the specified range (2.5-16 mm²), and verify the load does not exceed the 40A nominal current rating.
Difficulty inserting wire
Ensure the wire is stripped to the correct length and that no stray strands are present. Verify the wire gauge is within the 2.5-16 mm² range.
Screw terminal not tightening securely
Ensure the correct screwdriver type and size are used. Check for debris in the screw head or terminal. If the issue persists, the terminal may be damaged and require replacement.
