 Internal algorithms automatically reduce the maximum current limit when heat
sink temperature is above 85°C. Heat sink temperature is measured internally
near the power MOSFETs (see paragraph 6.6.1).
 Two-minute ratings are referred to an inverter equipped with a base plate. No
additional external heat sink or fans are used for the 2-minute rating test. Ratings
are based on an initial base plate temperature of 40°C and a maximum base
plate temperature of 85°C.
 The inverter can deliver the rated continuous current only if it is adequately
cooled. When it is equipped with its own finned heat sink, a proper dissipation is
obtained by applying a 100 m
3
/h airflow. In case it is provided with the base plate,
it is customer’s duty to design an adequate cooling system that can dissipate the
heat produced by the inverter, keeping its temperature below 85 °C. Otherwise,
the inverter will deliver a continuous RMS current lower than the rated one.
