Notes on ventilation with cold plate

Notes on ventilation with cold plate
With cold-plate cooling, the SINAMICS devices must always be ventilated separately by
means of a fan in the cabinet. Other suitable measures can be alternatively employed.
When using an external air heat sink, fans located outside the control cabinet must be
additionally used. Other suitable measures can be alternatively employed.
Temperature measurement
The temperature of the power units can be read out using a parameter (see the SINAMICS
S120/S150 List Manual).
Temperature limits
1. For the maximum heat sink temperature, see the "Technical data" for the power units.
2. For the maximum temperature inside the control cabinet, see the "Technical data" for the
