CAUTION
The DC link side covers are supplied as standard with the components; they can also be
ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).
If the Line Module is not disconnected from the network (e.g. via the main contactor or main
circuit-breaker), the DC link remains charged.
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.
