Siemens SINAMICS PERFECT HARMONY GH150 - 3.9 Interfaces; 3.9.1 Hydraulic interfaces; 3.9.2 Electrical interfaces

3.9 Interfaces
3.9.1 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.
