Note
 When encasing multiple inverters, install them in parallel as a cooling
measure.
 Install the inverter vertically.
 For heat dissipation and maintenance, take at least the clearances
shown in the table below from the inverter to the other devices and to
the enclosure surface.


Take 5cm or more clearances for 5.5K or higher.

When using the inverters at the surrounding air temperature of 40C or less, the inverters can be installed without any clearance between
them (0cm clearance).
(2) Environment
Before installation, check that the environment meets the specifications on page 45.
Note
 Install the inverter on a strong surface securely and vertically with bolts.
 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 designing or building an enclosure for the inverter, carefully consider influencing factors such as heat
generation of the contained devices and the operating environment.
