u Temperature Derating
As the ambient temperature for the drive is increased above the drive specification the drive should be derated. Additionally
parameter L8-35 Installation Method Selection on page 225 should be set according to enclosure type and mounting method
as illustrated in Figure A.1 .
n Output Current Derating Due to Ambient Temperature
Set L8-12 and L8-35 according to the installation conditions when the ambient temperature is above the drive specification
or when drives are mounted side-by-side in a cabinet. The output current is derated as shown in Figure A.1 .

u Altitude Derating
The drive standard ratings are valid for an installation altitude up to 1000 m. If the altitude exceeds 1000 m, both the drive
input voltage and the rated output current must be derated for 1% per 100 m. The maximum altitude is 3000 m.
