NOTE
1. The minimum mounting clearances stated in the table above applies to AC motor drives frame A to D. A drive fails
to follow the minimum mounting clearances may cause the fan to malfunction and heat dissipation problem.

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.
