For cabinet-mounted installations, ensure a calculated airflow volume sufficient to remove this heat. Maintain a minimum vertical clearance of 150 mm above and below the drive to prevent heat accumulation around the power modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Requirements\u003c\/strong\u003e: Use copper conductors rated for at least 75 deg C. Ensure the protective earth (PE) connection is firmly secured to the drive chassis, as the PE connection is vital for both safety and electromagnetic noise suppression in the HVAC control loop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreventative Inspection\u003c\/strong\u003e: Periodically check the cooling fan's intake for dust or debris.
