Encasing multiple inverters and converter units
Arrangement of the ventilation fan and inverter
When multiple inverters and converter units are placed in the
same enclosure, generally arrange them horizontally as shown
in the figure on the right.
Do not place multiple products vertically. The exhaust air
temperature of the inverter and the converter unit may be
increased.
When mounting multiple inverters and converter units, fully take
caution not to make the surrounding air temperature of the
inverter and the converter unit higher than the permissible value
by providing ventilation and increasing the enclosure size.
Arrangement of multiple inverters and converter units
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.)
