Arrangement of multiple inverters
When multiple inverters are placed in the same enclosure, generally arrange them horizontally as
shown in the fig. 2-13 (a). When it is inevitable to arrange them vertically to minimize space, take such
measures as to provide guides since heat from the bottom inverters can increase the temperatures in
the top inverters, causing inverter failures.
When mounting multiple inverters, fully take caution not to make the surrounding air temperature of
the inverter higher than the permissible value by providing ventilation and increasing the enclosure
size.
Arrangement of the ventilation fan and inverter
Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan.
When installing a ventilation fan for that heat, determine the place of ventilation fan installation after
fully considering an air flow. (Air passes through areas of low resistance. Make an airway and airflow
plates to expose the inverter to cool air.)
