-Certification Requirements: The product shall be certified with CCC certification (China Compulsory Product Certification) and a corresponding type test report; such documents may be requested from the manufacturer upon procurement.
-Environmental adaptability: For special application environments (e.g., regions with significant temperature variations such as Xinjiang, grid-connected photovoltaic systems, or data center rooms), additional requirements such as protection rating and temperature resistance range must be clearly specified during design.
-Maintainability: During design, consideration should be given to maintenance access and heat dissipation; wiring should be easy to maintain, and component layout should facilitate operation and replacement.
