The required airflow shown in chart is for installing single drive in a confined space.
When installing the multiple drives, the required air volume should be the required air volume for single drive multiplied by the
number of the drives.
Heat dissipation for each model is calculated by rated voltage, current and default carrier at full load, full speed, and maximum
ambient temperature
