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.

NOT E
The mounting clearances stated in the figure is for installing the drive in an
※
open area. To install the drive in a confined space (such as cabinet or
electric box), please follow the following three rules: (1) Keep the minimum
mounting clearances. (2) Install a ventilation equipment or an air
conditioner to keep surrounding temperature lower than operation
temperature. (3) Refer to parameter setting and set up Pr. 00-16, Pr.00-17,
and Pr. 06-55.
The following table shows the heat dissipation and the required air
※
volume when installing a single drive in a confined space. When
installing multiple drives, the required air volume shall be multiplied
by the number the 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.

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.
