• The required airflow shown in chart is for installing a single GS4 drive
in a confined space�
• When installing multiple GS4 drives, the required air volume would
be the required air volume for a single GS4 drive multiplied by the
number of GS4 drives�
• Heat dissipation shown in the chart is
for installing a single GS4 drive in a
confined space�
• When installing multiple drives, the
volume of heat dissipation should be
the heat dissipated by a single GS4
drive multiplied by the number of GS4
drives�
• Heat dissipation for each model is
calculated by rated voltage, current and
default carrier frequency�
1) External flow rate is across the heat sink.
Internal flow rate is through the chassis.
Published flow rates are the result of active cooling using fans; factory-installed in the drive.
Unpublished flow rates (-) are the result of passive cooling in drives without factory-installed
fans.
2) When calculating power dissipation (Watt Loss) use the total value if the drive is foot mounted,
or the internal value if the drive is flange mounted. Where only a total value is published, these
models cannot be flange mounted.
