1) Basic installation
When installing multiple inverters, leave at least 11 cm or more of space between each inverter
and install them aligned horizontally.
When using the inverter in locations with temperatures above 50°C, remove the top cover and
operation panel of the inverter (refer to [2. 2]) and use the inverter with the output current
reduced (refer to "Instruction manual for load reduction").
2) Side-by-side installation
To align the inverters side-by-side horizontally with no space, remove the top cover of the
inverter before use (refer to [2. 2]). When using the inverter in locations with temperatures
above 50°C, use the inverter with the operation panel removed and use the inverter with the
output current reduced (refer to "Instruction manual for load reduction").
The space shown in the figure above is the minimum allowable space. Because the inverter
has cooling fans built in on the top or bottom surfaces, make the space on top and bottom as
large as possible to allow for air passage.
