How to Fix / Troubleshooting

Critical safety: Overheating can lead to fire. If you see smoke, melting, or smell burning plastic, switch off the breaker immediately.

  • Stop charging: End the session and allow the connector and cable to cool completely.
  • Inspect for damage: Check the plug, cable, and EVBox socket (if present) for discoloration, cracks, or melted areas. Do not reuse damaged components.
  • Check cable rating: Ensure the cable is the original EVBox‑supplied cable and rated for the configured current.
  • Internal terminal check (qualified): With power off, open the EVBox and verify that all power terminals are tightened to the specified torque.
  • Replace affected parts: Replace any overheated connector, cable, or terminal block. Consider reducing maximum current if ambient temperatures are very high.
