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.

Figure 2. NI 9157/9159 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.

4| ni.com | NI 9157/9159 User Manual and Specifications

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.).

the DIN rail.

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

from the DIN rail.

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.

Installing C Series Modules

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.

3. Squeeze the latches and insert the I/O module into the module slot.

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.
