Installation of the inverter and enclosure design
2.3.4
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 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.
Allow clearance.

There needs to be a space of at least 30 cm in front of the inverter to replace the cooling fan. 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.
