To obtain the maximum allowable ambient temperature of 70 °C, you must mount the NI-9145 horizontally on a flat, metallic, vertical surface such as a panel or wall. You can mount the NI-9145 directly to the surface or use the NI Panel Mounting Kit. The following figure shows the NI-9145 mounted horizontally.

You can also mount the NI-9145 in other orientations, on a nonmetallic surface, on a 35-mm DIN rail, on a desktop, or in a rack. Mounting the NI-9145 in these or other configurations can reduce the maximum allowable ambient temperature and can affect the typical accuracy of modules in the NI-9145. For more information about typical accuracy specifications for C Series modules and temperature deratings caused by different mounting configurations, visit ni.com/r/criotypical.

Caution Make sure that no C Series modules are in the NI-9145 before mounting it.
Tip Before using any of these mounting methods, record the serial number from the back of the NI-9145 so that you can identify the NI-9145 in MAX. You will be unable to read the serial number after you mount the NI-9145.
