(inflow air temperature)
It is suggested to install a barrier
between the drives. Adjust
the size of the barrier until the
temperature of the fan on the
inflow side is lower than the
operation temperature. This barrier
is to prevent the lower drives’ hot
exhaust from going straight into
the upper drives’ intake.
(Refer to the right figure)
Operation temperature is the
temperature measured 50mm away
from the inflow side of the fan.

Note:
• The mounting clearances shown in figure to the left are NOT for installing the
GS4 drive in a confined space (such as cabinet or electric box). When installed in
a confined space, in addition to the minimum mounting clearances, ventilation
equipment or air conditioning should be installed to keep the surrounding
temperature lower than the operation temperature.
• The following table shows heat dissipation and required air volume when installing
a single GS4 drive in a confined space. When installing multiple drives, the required
air volume shall be multiplied by the number of GS4 drives.
• Refer to the chart (Air flow rate for cooling) for ventilation equipment design and
selection.
• Refer to the chart (Power Dissipation) for air conditioner design and selection.
• If GS4 drives in frames sizes A thru D are installed with clearance dimensions less
than specified, the cooling fans in these models may not adequately cool the drive.
