 Installing more than one unit in a cabinet
If you are installing two or more inverters in one cabinet, pay attention to the following.
 Inverters may be installed side by side with each other with no space left between them.
 When installing inverters side by side, detach the caution label on the top surface of each inverter and
use them where the ambient temperature will not rise above 40°C.
 When using inverters where the ambient temperature will rise above 40°C, leave a space of 3 cm or
more between them and remove the caution label from the top of each inverter, or operate each inverter
at a current lower than the rated one.
 Ensure a space of at least 20 centimeters on the top and bottom of the inverters.
 Install an air deflecting plate so that the heat rising up from the inverter on the bottom does not affect the
inverter on the top.
