NOTE:
⚫ 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.
⚫ 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.
⚫ Refer to the chart (Airflow Rate for Cooling) for ventilation equipment
design and selection.
⚫ Refer to the chart (Power Dissipation for AC Motor Drive) for air
conditioner design and selection.
⚫ Different control mode affects the derating. See Pr.H4-04 for more
information.
⚫ Ambient temperature derating curve shows the derating status in
different temperature in relation to different protection level.
⚫ Refer to the ambient temperature derating curve and derating curves
under different control modes in Chapter 11.
⚫ 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.
