6. Installation and Maintenance
Installation Notes
- Must be installed in a well-ventilated environment with appropriate temperature (recommended 5℃-40℃).
- The cabinet should be kept clean to avoid dust accumulation affecting heat dissipation.
- Wiring must follow the product manual to ensure reliable grounding and that the cross-sectional area of the protective cable meets the current capacity requirements.

Maintenance Recommendations
- Regularly check if the wiring terminals are loose, especially the input and output terminals.
- Clean the heat sink fan to ensure normal fan speed.
- Regularly read the operation log through the built-in diagnostic function or communication interface to prevent potential faults.
