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 dierent orientation or
on a nonmetallic surface can reduce the maximum allowable ambient temperature
and can aect 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.

Note For more information about typical accuracy specification for
modules, go to ni.com/info and enter the Info Code criotypical.
Caution Your installation must meet the following requirements for space
and cabling clearance:
■Allow 50.8 mm (2 in.) on the top and the bottom of the chassis for air
circulation.
■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.

The following sections contain instructions for the mounting methods. Before using
any of these mounting methods, record the serial number from the back of the
chassis. You will be unable to read the serial number aer you have mounted the
chassis.
Caution Make sure that no I/O modules are in the chassis before
mounting it.
Mounting the Chassis on a DIN Rail
Use the DIN rail mounting method if you already have a DIN rail configuration or if
you need to be able to remove the chassis quickly. You can order the NI 9916 DIN
rail mount kit if you want to mount the chassis on a DIN rail. You need one clip for
mounting the chassis on a standard 35 mm DIN rail. Complete the following steps to
mount the chassis on a DIN rail.
1. Fasten the DIN rail clip to the chassis using a number 2 Phillips screwdriver
and three M4 x 50 screws. NI provides these screws with the DIN rail mount kit.
Tighten the screws to a maximum torque of 1.3 N · m(11.5 lb · in.).
