WARNING
Danger of fire through overheating caused by insufficient ventilation and installation
Clearances
Insufficient ventilation and installation clearances result in overheating with danger to
persons as a result of smoke and fire.
 Always mount the Power Module in a vertical position.
 Maintain the following clearances between the components when mounting (*):
- Frame size FSA: 30 mm (1.18 inches)
- Frame size FSB: 40 mm (1.57 inches)
- Frame size FSC: 50 mm (1.96 inches)
 Maintain the following ventilation clearances 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)
- Frame size FSF: 350 mm (13.77 inches).
 Maintain the following ventilation clearances in front of the component:
- Frame sizes FSB to FSF: 30 mm (1.18 inches)
 Ensure that the cooling air flow of the Power Modules can flow unrestricted.
(*)The Power Modules can be mounted side by side without base components up to an
ambient temperature of 40° C.
In combination with base components and at ambient temperatures of 40° C to 55° C, the
specified lateral minimum clearances must be observed. Where combinations of different
frame sizes are concerned, the longer of the two clearances shall apply.
