Loose Cable Connections
-
Symptom: Localized thermal discolored housing or intermittent voltage drops.
-
Solution: Apply specified torque values using calibrated hex keys to secure the internal cable clamps completely.
Din Rail Misalignment
-
Symptom: Mechanical instability or shifting when adjacent circuit breakers trip.
-
Solution: Install heavy-duty end stops on both sides of the block to prevent lateral movement.
System Integration Conclusion
