Mounting the Chassis
In order to obtain the maximum allowable ambient temperature as specified in the
Environmental section of this document, you must mount the chassis horizontally on a flat,
vertical, metallic surface such as a panel or wall. You can mount the chassis directly to the
surface or you can use the NI Panel Mounting Kit. You can also mount the chassis in other
orientations, on a nonmetallic surface, on a 35-mm DIN rail, on a desktop, or in a rack. Mounting
the chassis in these or other configurations can reduce the maximum allowable ambient
temperature and can affect the typical accuracy of modules in the chassis. Figure 2 shows the
chassis mounted horizontally.

Figures 3 to 5 show the bottom, front, and side views with the dimensions of the chassis.

Note
Measure the ambient temperature at each side of the chassis, 63.5 mm
(2.5 in.) from the side and 25.4 mm (1 in.) forward from the rear of the chassis, as
shown in Figure 3.
Caution
Your installation must meet the following requirements for space and
cabling clearance:
• Allow 50.8 mm (2 in.) on the top and bottom of the chassis for air circulation,
as shown in Figure 4.
• Allow 50.8 mm (2 in.) in front of modules for cabling clearance for common
connectors, such as the 10-terminal, detachable screw terminal connector, as
shown in Figure 3.
