Inverter installation
Inverter placement
• 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 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 replacing the cooling fan, 30 cm or more of space is necessary in front of the inverter. Refer to
Installation orientation of the inverter
Install the inverter on a wall as specified. Do not mount 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.
