To ensure proper functionality during use at the maximum ambient temperature of 70 °C, you must mount the cDAQ chassis in the reference mounting configuration shown in the following image. Mounting the cDAQ chassis 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 cDAQ chassis in the reference mounting configuration.

Figure 14. cDAQ Chassis Reference Mounting Configuration (cDAQ-9189 Shown)
  1. Horizontal mounting orientation
  2. Panel mounting
  3. Observe the cooling dimensions in the Mounting Requirements section
  4. Allow space for cabling clearance according to the Mounting Requirements section
Note Panel mounting substrate options:
  • Mount the cDAQ chassis 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-9905 Panel Mounting Kit to mount the cDAQ chassis 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.

Before using any of these mounting methods, record the serial number from the back of the cDAQ chassis so that you can identify the cDAQ chassis in MAX. You will be unable to read the serial number after you mount the cDAQ chassis.
