7) Note the cooling method when the inverter is installed in an enclosure.
When two or more inverters are installed or a ventilation fan is mounted in an
enclosure, the inverters and ventilation fan must be installed in proper positions with
extreme care taken to keep the ambient temperatures of the inverters with the
permissible values. If they are installed in improper positions, the ambient
temperatures of the inverters will rise and ventilation effect will be reduced.
8) Install the inverter securely in the vertical direction with screws or bolts.
