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. (Air flow must not be interrupted in the 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.
