Siemens SINAMICS S120 Manual page 65

Power Modules must be mounted in the vertical position.
For the Power Modules, the following cooling clearances must be maintained above and
below the component:
- frame sizes FSA and FSB: 100 mm (3.93 inches),
- frame size FSC: 125 mm (4.92 inches),
- frame sizes FSD and FSE: 300 mm (11.81 inches) and
- frame size FSF: 350 mm (13.77 inches).
When mounting the Power Modules, the following clearances must be maintained between
the components:
- frame size FSB: 40 mm (1.57 inch)
- frame size FSC: 50 mm (1.96 inch)
Power Modules of frame sizes FSA, FSD, FSE and FSF can be mounted without any
lateral clearance.
Devices, that could restrict the cooling air flow may not be mounted/installed in this area. It
must be carefully ensured that the cooling air flow of the Power Modules can flow
unrestricted.
Cable shields and unused power cable conductors (e.g. brake conductors) must be
connected to PE potential to prevent capacitive cross-talk charges.
Non-observance can cause lethal shock voltages.
