1) If the frequency inverter is to be installed in a control panel, enclosure or similar installation, the temperature within the enclosure or control panel is
considered to be ambient temperature T

.
All power section ratings are based on an operating frequency of 5 kHz (default) and an ambient temperature of +40 °C, during operation of a four-
pole three-phase asynchronous motor.
