• 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-F820-00250(5.5K) or lower and FR-F840-00126(5.5K) or lower, allow 1 cm or more clearance.

When using the FR-F820-01250(30K) or lower and FR-F840-00620(30K) 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-F840-04320(185K) or higher, 30 cm of space is necessary in front of the inverter.
Refer to the Instruction Manual (Detailed) for fan replacement.
