7. Troubleshooting Points

1. No Power: Verify if the connector is properly tightened (0.6 Nm torque).

2. Wrong Pin Configuration: Confirm pin color and placement match circuit diagram.

3. Intermittent Connection: Check for cable bending beyond radius (min. 10× diameter).

4. Mechanical Damage: Inspect cable for cuts or abrasions.

5. Water Ingress: Ensure IP65/IP67 rating is maintained at connection.

6. Connector Loose: Confirm screw-lock is tight and self-locking is engaged.

7. Incorrect Voltage: Check power supply does not exceed 250 V AC/DC.

8. Corrosion: Ensure nickel-plated connector is not exposed to highly corrosive environments.

9. Chemical Attack: Although resistant, verify compatibility with new chemicals.

10. Cable Break: Test continuity in each conductor.

11. Connector Overheating: May indicate electrical overload.

12. Signal Noise: Not shielded – avoid placing near high EMI sources.

13. Wrong Use in Drag Chain: Not suitable for dynamic cable carrier use.

14. Discoloration: Indicates overheating or chemical reaction.

15. Cracking Sheath: Likely from incorrect temperature application.

16. Mismatched Coding: Ensure A-coded connector matches device port.

17. Cable Pull-Out: Use strain reliefs where needed.

18. Loose Internal Wire: Perform pin-out testing.

19. Wrong Connector Type: Double-check female/male configuration.

20. Overbending: Especially during installation; check minimum bend radius.

21. Cable Too Short: Always verify application length requirement.

22. Cable Too Long: May introduce voltage drop in sensitive circuits.

23. Unsecured Cable: Secure with clips or tie-wraps.

24. Wrong Color Coding: Cross-check datasheet with real wire color.

25. No LED: This model does not support diagnostic LED.

26. Wrong ECLASS or ETIM for Procurement: Ensure compatibility with system requirements.

27. Cable Misrouted: Avoid routing near sharp or hot surfaces.

28. PVC Wear: Excessive movement may degrade outer insulation.

29. Incorrect Storage Temperature: Store in the range allowed by specs.

30. Unapproved Use Case: Avoid using in applications needing flame-proof or shielded cables.
