※ 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 X the number of the drives.
※ The heat dissipation shown in
the chart is for installing single
drive in a confined space.
※ When installing the multiple
drives, volume of heat
dissipation should be the heat
dissipated for single drive X the
number of the drives.
※ Heat dissipation for each model
is calculated by rated voltage,
current and default carrier.
