Siemens SINAMICS SM120 - Additional Leakage Water Sensors in the Power Units (Option W26); Interfaces; Hydraulic Interfaces; Electrical Interfaces

3.5.16 Additional leakage water sensors in the power units (option W26)
Additional leakage water sensors are installed in the power units.
3.6 Interfaces
3.6.1 Hydraulic interfaces
The cooling circuit dissipates the semiconductor losses. The water flows into the cooling circuit
through the inlet pipe. The water is heated by the waste in the semiconductors. The water
flows out through the return pipe.
