Derating vs. ambient temperature:
The performance data are reduced by the fac‐
tor F
Ta
in the ambient temperature range
T

:
F
TA
= 1 - [(T

]
Example: With an ambient temperature
T
a
= 50 °C and a capacity utilization factor
f
Ta
= 2%, the rated power is reduced to

Derating vs. installation altitude:
At an installation altitude h > h

, the per‐
formance data reduced by factor f 2) are availa‐
ble.
At an installation altitude in the range

, an isolating transformer has
to be installed at the drive system mains con‐
nection.
