 Inverter placement
Fix six positions for the FR-F840-04320(185K) or higher.
• 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 in an enclosure, install them in parallel as a cooling measure.
• For heat dissipation and maintenance, keep clearance between the inverter and the other devices or enclosure surface.
The space below the inverter is required for wiring, and the space above the inverter is required for heat dissipation.
• 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.

Enclosure structure
This system is low in cost and generally used, but the
enclosure size increases as the inverter capacity
INV
increases. This system is for relatively small capacities.
Being a totally enclosed type, this system is the most
appropriate for hostile environment having dust, dirt, oil
mist, etc. The enclosure size increases depending on
INV
the inverter capacity.
This system has restrictions on the heat sink mounting

This system is for general indoor installation. This is
appropriate for enclosure downsizing and cost
