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 Technical News (MF-Z-116) contained in the enclosed CD-ROM.

• 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.

Allow clearance.

For the FR-A820-00250(3.7K) or lower and FR-A840-00126(3.7K) or lower, allow 1 cm (0.39 inches) 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 (104°F) or less (30°C (86°F) 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.
