REVIEW OF INSTALLATION ENVIRONMENT
(4) Interference of heat inside the enclosure and ventilation
The arrangement of the inverter and ventilation fan is one of the important points when they are
installed in the enclosure.
When installing multiple inverter or a ventilation fan in the enclosure, note that the surrounding
air temperature of the inverter increases or the ventilation becomes less effective depending on
the installing position.
