To obtain the maximum ambient temperature, you must mount the cRIO-905x in the reference mounting configuration shown in the following figure. 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.

Figure 10. System Mounting Configuration


Horizontal mounting orientation.
Mounting substrate options:
  • Mount the cRIO-905x directly to a metallic surface that is at least 1.6 mm (0.062 in.) thick and extends a minimum of 101.6 mm (4 in.) beyond all edges of the device.
  • Use the NI Panel Mounting Kit to mount the cRIO-905x to a metallic surface that is at least 1.6 mm (0.062 in.) thick and extends a minimum of 101.6 mm (4 in.) beyond all edges of the device.
Observe the minimum spacing dimensions listed in Mounting Requirements.
Allow space for cabling clearance according to Mounting Requirements.
Tip Before mounting the controller, record the serial number from the side of the cRIO-905x so that you can identify the cRIO-905x in MAX. You will be unable to read the serial number after you mount the controller.
