Safety instructions for Power Modules blocksize format
Danger to life if the fundamental safety instructions and residual risks are not observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Observe the fundamental safety instructions.
• Consider the residual risks for the risk evaluation.
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. Further, increased failures can occur and the service
life of units/systems shortened.
• Always mount Power Modules in a vertical position.
• Maintain the following clearances between the components when mounting
1)
:
– 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)
• Do not install devices in this area that could obstruct the cooling airflow.
• Ensure that the cooling air flow of the Power Modules can flow unrestricted.
1)
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.
