(1)
Heatsink air inlet temperature.
(2)
If the 2 parts of the inverter are in the same environment, this is the maximum temperature around the inverter.
(3)
If the 2 parts of the inverter are installed in different compartments (flange mounting), this is the maximum temperature around the front of
the inverter.
(4)
Exception: models CFW900C74P0T4 and CFW900D0146T4 that have specification of 55 °C (131 °F). For operation above 55 °C it is
necessary to apply derating of 2 %/°C.
