Inverter placement
Installation environment
Before installation, confirm that the following environment conditions are met.
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.
For the amount of heat generated by the inverter unit, refer to the Instruction Manual (Detailed) of the FR-A800 series inverter contained in the enclosed CD-ROM.

Installation on the enclosure
• As the inverter does not have an explosion proof structure, install it in a non-hazardous place.
• 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.
For the 3700 or lower, allow 1 cm or more clearance.
When using the 22K or lower at the surrounding air temperature of 40°C or less, side-by-side installation (0 cm clearance)
is available.
