Power Modules
3.1 Power Modules Blocksize (PM340)
Caution
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 A and B: 100 mm (3.93 inch),
- frame size C: 125 mm (4.92 inches),
- frame sizes D and E 300 mm (11.81 inches) and
- frame size F: 350 mm (13.77 inches).
When mounting the Power Modules, the following clearances must be maintained between
the components:
- frame size B: 40 mm (1.57 inch)
- frame size C: 50 mm (1.96 inch)
Power Modules frame sizes A, D, E and F 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.
Danger
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.
