6.2.2 Derating of Electric Data
Derating and ambient temperature
The ambient temperature for Frequency Converter EFC x610 is -10...55 ℃. Out
of this range, there will be no possibility to install and run the frequency con-
verter, even the performance data have been additionally reduced.
● If the ambient temperature is -10...45 ℃, there will be no need for derating.
● If the ambient temperature is 45...55 ℃, derating must be performed as indi-
cated in the figure below.
