NI cDAQ-9132/9133/9134/9135/9136/9137 User Manual
Caution
You must mount the controller horizontally on a flat, vertical, metallic
surface to achieve the maximum allowable operating ambient temperature
1
.
Mounting the controller in a different orientation or on a nonmetallic surface reduces
the maximum allowable ambient temperature and can affect the measurement
accuracy of modules in the controller. Figures 1-8 and 1-9 show the controller
mounted horizontally. Refer to the
complete panel mounting instructions.
Measure the ambient temperature at each side of the controller, 63.5 mm (2.5 in.)
from the side and 38.1 mm (1.5 in.) forward from the rear of the controller, as shown
in Figures 1-10 and 1-11.
For more information about how different mounting configurations can cause temperature
derating, go to
