When multiple inverters and converter units are placed in the same enclosure, arrange them horizontally as shown in the figure
below.
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 the ventilation fan and the converter unit
Heat generated in the converter unit 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 converter unit to cool air.)

Protruding the heat sink through a panel
When encasing the converter unit to an enclosure, the heat generated in the enclosure can be greatly reduced by protruding
its heat sink through the rear panel of the enclosure.
When installing the inverter in a compact enclosure, etc., this installation method is recommended.
