• 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-A860-00090 or lower, allow 1 cm or more clearance.

For replacing the cooling fan of the FR-A860-02890 or higher, 30 cm of space is necessary in front of the inverter.
Refer to the Instruction Manual (Detailed) for fan replacement.
