Installation Guidelines

• Mounting: Mount the drive vertically on a flat, non-flammable surface to ensure optimal heat dissipation through the integrated heat sink.
• Ventilation: Maintain mandatory clearance distances above and below the drive to facilitate airflow. Avoid restricted spaces that cause heat recirculation.
• Grounding: Securely connect the drive chassis to the main protective earth (PE) busbar to prevent electrical noise and ensure safety.
• Wiring: Keep high-voltage power lines and low-voltage control signal wires in separate cable trays to prevent electromagnetic interference (EMI).
• Environment: Ensure the ambient operating temperature and humidity are within the product's rated limits to protect internal control electronics.
