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
• Maintain the following ventilation clearances above and below the component:
• Maintain the following ventilation clearances in front of the component:
• 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.
The Power Modules can be mounted side by side without base components up to an
1)
ambient temperature of 40° C.
In combination with base components and at ambient temperatures of 40° C to 55° C, the
