Encasing multiple inverters and converter units
When multiple inverters and converter units are placed in the same enclosure, generally arrange them horizontally as shown
in the figure below. 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 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.)

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