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 of 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.
Different control mode will affect the derating. See Pr.06-55 for
※
more information.
Ambient temperature derating curve shows the derating status in
※
different temperature in relation to different protection level.
Refer to Chapter 9-4 for ambient temperature derating curve and
※
