Installation orientation of the inverter Install the inverter on a wall as specified. Do not mount it horizontally or in any other way. Above the inverter Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be heat resistant. Arrangement of multiple inverters When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the figure (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.

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.) Inverter Arrangement of the ventilation fan and inverter 28 2. INSTALLATION AND WIRING 2.3 Installation of the inverter and enclosure design Inverter
