3: External Heatsink Installation, Finless Drive
Drive operation between -10C and 40C allows 100% continuous current without derating. Operation between 40C
and 50C requ
ires output current derating.

 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
rated voltage and the rated output current must be derated for 1% per 100 m. The maximum altitude is 3000 m.
