Installation Guidelines

• Mount the inverter vertically on a flat, non-flammable vertical surface (such as a metal plate) to ensure optimal heat dissipation.
• Maintain a minimum clearance of 50 mm above and below the unit, and 10 mm on both sides. For side-by-side installation, ensure ambient temperature does not exceed 40 degC.
• Operate within an ambient temperature range of -10 degC to 50 degC (non-freezing).
• Ensure proper grounding by connecting the ground terminal to a dedicated Class D ground (ground resistance of 100 ohms or less).
• Use shielded cables for all control and signal wiring, routing them away from high-voltage power cables to prevent electromagnetic interference.

Compliance and Certifications

• CE (Low Voltage Directive, EMC Directive)
• UL Listed / cUL
• CCC (China Compulsory Certification)
• RoHS Compliant
