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.
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 after 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.).

Mounting the Chassis on a Flat Surface Using the
NI 9907 Panel Mount Kit
Panel or wall mounting is the best method for applications that are subject to high shock and
vibration. You can use the NI 9907 panel mount kit to mount the NI 9157/9159 on a flat
surface. Complete the following steps.
1. Fasten the chassis to the panel mount kit using a number 2 Phillips screwdriver and six
M4 x 50 screws. NI provides these screws with the panel mount kit. Tighten the screws to
a maximum torque of 1.3 N · m (11.5 lb · in.).

2. Fasten the panel mounting plate to the surface using the screwdriver and screws that are
appropriate for the surface. The maximum screw size is M4 or number 8.
Caution Make sure that no I/O modules are in the chassis before removing it from
the panel.
Mounting the Chassis Directly on a Flat Surface Using
the Mounting Holes
Panel or wall mounting is the best method for high shock and vibration applications. If you do
not have the NI 9907 panel mount kit and do not require the portability that the NI 9907
affords, you can mount the NI 9157/9159 directly on a flat surface using the three mounting
holes. Complete the following steps.
1. Align the chassis on the surface.
2. Fasten the chassis to the surface using three M4 or number 8 screws. NI does not provide
these screws with the chassis.

Caution Make sure that no I/O modules are in the chassis before removing it from
the panel.

Complete the following steps to install a C Series I/O module in the chassis.
1. Make sure that no I/O-side power is connected to the I/O module. If the system is in a
nonhazardous location, the chassis power can be on when you install I/O modules.
2. Align the I/O module with an I/O module slot in the chassis. The module slots are labeled
1 to 14, left to right.

4. Press firmly on the connector side of the I/O module until the latches lock the I/O module
into place.
5. Repeat these steps to install additional I/O modules.
Removing C Series Modules
Complete the following steps to remove a C Series I/O module from the chassis.
1. Make sure that no I/O-side power is connected to the I/O module. If the system is in a
nonhazardous location, the chassis power can be on when you remove I/O modules.
2. Squeeze the latches on both sides of the module and pull the module out of the chassis.
