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.
Installation environment
Before installation, confirm that the following environment conditions are met.
LD, ND (initial setting), HD
Surrounding air
temperature
SLD
Ambient humidity
Storage temperature
Atmosphere
Altitude
Vibration
Temperature applicable for a short time, e.g. in transit.
For the installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.
2.9 m/s
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.
There needs to be a space of at least 30 cm in front of the inverter to replace the cooling fan of the FR-A840-04320(160K)
or higher.
Refer to the Instruction Manual (Detailed) for fan replacement.
