NOTE:
âš« The mounting clearances stated in the figure is for installing the
drive in an open area (as shown in the figure on the left). To install
the drive in a confined space (such as cabinet or electric box), follow
the following 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 Parameters A5-00 and H4-04.
âš« The table below lists the required air volume of each model for
installing single drive in a confined space. When installing multiple
drives, the required air volume shall be multiplied by the number of
the drives.
âš« Refer to the chart (Airflow Rate for Cooling) for ventilation equipment
design and selection.
âš« Refer to the chart (Power Dissipation for AC Motor Drive) for air
conditioner design and selection.
âš« Different control mode affects the derating. See Pr.H4-04 for more
information.
âš« Ambient temperature derating curve shows the derating status in
different temperature in relation to different protection level.
âš« Refer to the ambient temperature derating curve and derating curves
under different control modes in Chapter 11.
âš« If UL Type 1 models need side by side installation, remove the top
cover for Frame A–C. Do NOT install the conduit box for Frame D
and above.
