Troubleshooting
Connection appears loose
Ensure the wire is properly stripped and inserted fully into the terminal. Retighten the screw connection with appropriate torque. Verify the wire gauge is within the specified range.
Terminal block not seating correctly on mounting rail
Confirm that you are using a compatible mounting rail (NS 35/7.5, NS 35/15, or NS 32). Check the rail for any damage or obstructions.
Overheating at connection point
Check if the current exceeds the rated 41A. Ensure the screw connection is tight. Verify the wire gauge is appropriate for the current being carried and the terminal block's specifications.
