To obtain the maximum ambient temperature, you must mount the cRIO-905x in the reference mounting configuration shown in the following image. Mounting the cRIO-905x in the reference mounting configuration ensures that your system will operate correctly across the full operating temperature range and provide optimal C Series module accuracy. Observe the following guidelines to mount the cRIO-905x in the reference mounting configuration.
|Vertical mounting orientation.|
|Mounting substrate options:
|Observe the minimum spacing dimensions in Mounting Requirements for the cRIO-905x.|
|Allow space for cabling clearance according to Mounting Requirements for the cRIO-905x.|
The maximum operating temperature may be reduced for any mounting configuration other than the reference mounting configuration. A 10 °C (18 °F) reduction in maximum operating temperature is sufficient for most alternate mounting configurations. Follow the guidelines above for all mounting configurations. The published accuracy specifications, although not guaranteed for alternate mounting configurations, may be met depending on the system power and the thermal performance of the alternate mounting configuration. Contact NI for further details regarding the impact of common alternate mounting configurations on maximum operating temperature and module accuracy.
