Installation of the inverter
1.3
Environment
Before installation, check that the environment meets following specifications:
*4
Temperature applicable for a short time, e.g. in transit.
*5
For the installation at an altitude above 1,000m up to 2,500m, derate the rated current 3% per 500 m.
*6
Surrounding air temperature is a temperature measured at a measurement position in an enclosure. Ambient temperature is a
temperature outside an enclosure.
*7
2.9m/s
2
or less for the FR-A840-04320(160K) or higher
Install the inverter on a strong surface securely with bolts.
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 surface.
When encasing multiple inverters, install them in parallel as a cooling measure.
*1
For the FR-A820-00250(3.7K) or lower, the FR-A840-00126(3.7K) or lower, and the FR-A846-00126(3.7K) or lower allow 1cm or more clearance.
*2
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 (0cm clearance) is available.
*3
For replacing the cooling fan of the FR-A840-04320(160K) or higher, and of the FR-A842 models, 30cm of space is necessary in front of the inverter.
Refer to the Instruction Manual for fan replacement.
