Electrical Connection - Siemens SINAMICS S120 Equipment Manual

Note
The fans are power-up and power-down as a function of the heatsink temperature.
The fans start up at the heat-sink temperature specified in the power stack data (normally
56 °C) and are switched off with a slight hysteresis when the heat-sink temperature
decreases again. The length of time it takes for the fans to stop once they have been
switched off depends on a number of factors (ambient temperature, output current, duty
cycle, etc.) and, therefore, cannot be determined directly.
The fans are not equipped with temperature-dependent speed control; they are either ON
or OFF.
