Technical Specifications

Installation Guidelines

• Mounting: Mount the inverter vertically on a flat, non-combustible surface to facilitate natural convective cooling.
• Clearance: Maintain a minimum clearance of 50 mm above and below the drive, and 10 mm on both sides to prevent thermal buildup.
• Grounding: Always connect the protective earth (PE) terminal to a dedicated ground point to prevent electrical shock and reduce noise.
• Wiring: Isolate control signal wires from high-voltage power cables. Use shielded twisted-pair cabling for all RS-485/422/232 communications.
