NOTE
• In this Instruction Manual, the inverter model name consists of the applicable motor capacity and the rated current. (Example) FR-A820-00046(0.4K)
Inverter placement
Installation on the enclosure
Fix six positions for the FR-A840-04320(160K) or higher.

or less for the FR-A840-04320(160K) or higher.
Surrounding air temperature is a temperature measured at a measurement position in an enclosure.
Ambient temperature is a temperature outside an enclosure.
For the amount of heat generated by the inverter unit, refer to the Instruction Manual (Detailed).

• Install the inverter on a strong surface securely with screws.
• Leave enough clearances and take cooling measures.
• Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.
• Install the inverter on a nonflammable wall surface.
• When encasing multiple inverters, install them in parallel as a cooling measure.
• When designing or building an enclosure for the inverter, carefully consider influencing factors such as heat generation
of the contained devices and the operating environment.

Allow clearance.
For the FR-A820-00250(3.7K) or lower and FR-A840-00126(3.7K) or lower, allow 1 cm or more clearance.
When using the FR-A820-01250(22K) or lower and FR-A840-00620(22K) or lower at the surrounding air temperature of
40°C or less (30°C or less for the SLD rated inverter), side-by-side installation (0 cm clearance) is available.
For replacing the cooling fan of the FR-A840-04320(160K) or higher, 30 cm of space is necessary in front of the inverter.
Refer to the Instruction Manual (Detailed) for fan replacement.
