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.
