■ When more than one inverter are installed in one cabinet
When two or more inverters are installed in one cabinet, pay attention to the followings.
• Ensure a space of at least 20 cm or more on the top and bottom of the inverters.
(Note: Depending on the inverter type.)
• 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.
• Inverters may be installed side by side with each other with no space left between them.
When installing inverters side by side, remove the top cover of the inverter. For how to remove,
refer to [2. 2].
When using the inverter in locations with temperatures above 50°C, use the inverter with the oper-
ation panel removed and the output current reduced.
