WARNING
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.
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. Further, increased failures can occur and the service
life of units/systems shortened.
• Always install the Power Modules vertical with the line and motor connections at the
bottom.
• Ensure a 1 mm clearance between mounted components.
• Maintain the following ventilation clearances above and below the component:
– Above: 80 mm (3.15 inches)
– Below: 100 mm (3.93 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.
