Inverter installation
Inverter placement
• Install the inverter on a strong flat 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.
• For heat dissipation and maintenance, keep clearance between the inverter and the other devices. The clearance below
the inverter is required as a wiring space, and the clearance above the inverter is required as a heat dissipation space.
• 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-A846-00126(3.7K) or lower, allow 1 cm or more clearance.
 Installation orientation of the inverter
Install the inverter on a wall as specified. Do not install it horizontally or in any other way.
Above the inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be
heat resistant.
Fix six positions for the FR-A846-01800(55K) or higher.
