Mounting the NI 9157/9159
You can mount the chassis horizontally on a 35 mm DIN rail or on a flat, vertical, metallic
surface such as a panel or wall. The maximum allowable ambient temperature for operation is
55 °C. Mounting the chassis in a different orientation or on a nonmetallic surface can reduce
the maximum allowable ambient temperature and can affect the typical accuracy of modules in
the chassis. The following figure shows the chassis mounted horizontally.

Measure the ambient temperature at each side of the chassis, 63.5 mm (2.5 in.) from the side
and 50.8 mm (2 in.) forward from the rear of the chassis.
