NI cDAQ-9181/9184/9188/9191 User Manual
• Panel Mounting without a Panel Mount Kit—You can mount the cDAQ chassis directly
on a flat surface using the mounting holes. Align the chassis on the surface. Then, fasten
the chassis to the surface using two screws as shown in Figure 1-16. The cDAQ-9184 uses
two M4 or No. 8 flathead screws. The cDAQ-9188 uses two M4 or No. 8 panhead screws.
National Instruments does not provide these screws with the chassis.
Figure 1-16. Mounting the cDAQ Chassis Directly on a Flat Surface
Refer to the specifications document for your cDAQ chassis for mounting dimensions.
Caution Make sure that no modules are in the chassis before removing it from the
surface.
Mounting the cDAQ Chassis on a DIN Rail
Caution To maintain product performance and accuracy specifications when the
ambient temperature is between 45 °C and 55 °C, you must mount the chassis to a
metal panel or surface using the screw holes or the panel mount kit. DIN mounting
limits the device to 45 °C maximum ambient operating temperature. Measure the
ambient temperature at each side of the CompactDAQ system 63.5 mm (2.5 in.) from
the side and 25.4 mm (1 in.) from the rear cover of the system. For further
information about mounting configurations, go to
ni.com/info and enter the Info
Code cdaqmounting.
You can use a DIN rail kit to mount the cDAQ chassis to a standard DIN rail. For kit accessory
ordering information, refer to the pricing section of your cDAQ chassis product page at ni.com.
