Operation without the line reactor is not permissible.

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.

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; Only the states on or
