A-1  Derating 
 
If you intend to use the inverter models with “Yes” in the column “Derating” of the following table at an 
ambient temperature of 40°C or higher, or to use more than one inverter installed next to each other 
(side-by-side installation), you need to derate the output current as shown in the graphs below. (The 
ambient temperature specification for side-by-side installation is −10 to 40°C.) 
In the 1st/2nd Electronic Thermal Level (b012/b212), set the output current value to be derated. For 
details on the electronic thermal level, refer to 5-3-2 Electronic Thermal Function on page 5-15. 
 
 
 
Note Yes: Derating is necessary, No: Derating is Not necessary 
 
 
For the inverter models with “No” in the column “Derating” of the above table, setting is not necessary to 
derate the output current. Use the inverter within the range of the rated specifications.
