6.2.2 Derating of Electric Data
Derating and ambient temperature
The ambient temperature for Frequency converter VFC 3210 is -10...50 ℃. Out of
this range, there will be no possibility to install and run the frequency converter,
even the performance data have been additionally reduced.
●
If the ambient temperature is -10...40 ℃, there will be no need for derating.
●
If the ambient temperature is 40...50 ℃, derating must be performed as indi-
cated in the figure below.
