📋 Routine Maintenance

1. Check operating conditions: temperature, humidity, I/O voltage, frequency, LED indicators, alarms
2. Check for abnormal noise; inspect fans and modules
3. Inspect AC/DC terminals for tightness, cables for integrity
4. Verify system monitoring panel: all units normal, no faults or alarms
5. Clean dust from equipment as needed
6. Record ambient temperature and humidity
7. Verify module parameter configuration

🔄 Replacement Procedure

1. Remove the faulty module (caution: high internal temperature or residual voltage)
2. Confirm the new module is intact
3. Shut down all running modules in the system
4. Open AC/DC breakers of the faulty module; loosen fixing screws
5. Grasp the handle and slowly pull out
6. Align the new module with the slot and push it in slowly until firmly seated
7. Secure with fixing screws
8. Close AC/DC breakers
9. Verify monitoring panel recognizes the new module, communication is normal, current sharing is balanced
