Installation Guidelines

• Mounting: Given the weight of 48.50 kg, ensure the cabinet mounting structure is reinforced and capable of supporting the drive securely. Mount in a vertical position with adequate clearance for airflow.
• Environment: The operating environment must be clean, dry, and free from conductive dust, moisture, and corrosive substances.
• Wiring: Connect the 3-phase power supply and motor leads securely using appropriately sized cables for a 75 kW load. Utilize shielded cables to maximize the effectiveness of the integrated EMC filter.
• Grounding: Establish a heavy-duty ground connection from the drive chassis to the system ground bus to ensure operator safety and reduce electrical noise.
• Cooling: Ensure the control cabinet has active ventilation or air conditioning to maintain an ambient temperature within the drive's specified operating range.
