Installation Guidelines

• Mounting: Install the drive in a vertical position inside a control panel. Ensure adequate spacing around the unit for proper heat dissipation.
• Environment: The installation location must be clean, dry, and protected from excessive dust, corrosive gases, and moisture. Ensure the operating ambient temperature is within specifications.
• Wiring: Connect the 3-phase power supply and motor leads securely. Use shielded cabling for motor connections to ensure compliance with the integrated EMC filter standards.
• Grounding: Establish a solid ground connection from the drive chassis to the system ground bus to prevent electrical noise and ensure operator safety.
• Ventilation: Ensure that the cabinet has adequate air intake and exhaust. If installed in a closed cabinet, supplemental cooling (fans) may be required to maintain performance.
