2) ABB additional extension to ambient surrounding temperature, outside the cabinet, -30 °C…55 °C (-22 °F…131 °F). See
also the instructions for ambient temperature derating.
3) L denotes service life >15 years.
Disclaimer
The customer shall ensure that the environmental conditions inside the wind turbine is maintained in order to
fulfill the environmental classifications and/or corrosion class, as herein stated. If the operational condition is
out of any environmental classifications and/or corrosion class, the expected lifetime of the converter may be
risked and the ABB converter warranty is terminated. If the customer is unsure about the environmental con-
ditions and/or corrosion class inside the wind turbine, the customer is responsible for contacting ABB before
the converter installation, and get an approval from ABB to use the converter in such an environmental condition
and/or corrosive class.
