which software you need to use the cRIO-9075/9076.

Mounting the cRIO-9075/9076

You can mount the chassis horizontally on a flat, vertical, metallic surface

such as a panel or wall. The maximum allowable ambient temperature for

operation in this configuration is 55 °C. Figure 2 shows the chassis

mounted horizontally.

Figure 2. cRIO-9075/9076 Mounted Horizontally

You can also mount the chassis on a panel or wall in other orientations, on

a non-metallic surface, on a 35 mm DIN rail, on a rack, in an enclosure, or

on a desktop. 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.

Note For information about how different mounting configurations can cause temperature

derating, go to ni.com/info and enter the Info Code criomounting.

Note For information about typical accuracy specifications for modules, go to

ni.com/info and enter the Info Code criotypical.

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 25.4 mm (1 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, as shown

in Figure 3.

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 Flat Surface

Using the NI 9904 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 9904 panel mount kit to

mount the cRIO-9075/9076 on a flat surface. Complete the following steps.

1. Fasten the chassis to the panel mount kit using a number 2 Phillips

screwdriver and two M4 ×25 screws. National Instruments provides

these screws with the panel mount kit. You must use these screws

because they are the correct depth and thread for the panel. Tighten the

screws to a maximum torque of 1.3 N ⋅m (11.5 lb ⋅in.).

2. Fasten the NI 9904 panel to the wall using the screwdriver and screws

that are appropriate for the wall surface. The maximum screw size is

M4 or number 8.

Mounting the Chassis Directly on a Flat Surface

Using the Mounting Holes

Panel or wall mounting is the best method for applications that are subject

to high shock and vibration. If you do not have the NI 9904 panel mount kit

and do not require the portability that the NI 9904 affords, you can mount

the chassis directly on a flat surface using the mounting holes. Complete

the following steps.

1. Align the chassis on the surface.

2. Fasten the chassis to the surface using M4 or number 8 flathead screws,

as shown in Figure 8. National Instruments does not provide these

screws with the chassis.

surface.

Mounting the Chassis on a DIN Rail

Using the NI 9912 DIN Rail Mount Kit

You can order the NI 9912 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 two M4 ×25 screws. National Instruments 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 Desktop

Using the NI 9901 Desktop Mounting Kit

You can use the NI 9901 desktop mounting kit to mount the chassis on a

desktop. You must install the adapter bracket using two M3 ×20 screws.

The adapter bracket and the screws are included in the kit. Refer to the

NI 9901 documentation for information about mounting the chassis on a

desktop.

Installing C Series I/O Modules in the Chassis

Figure 11 shows the mechanical dimensions of C Series I/O modules.

Figure 11. C Series I/O Module, Front and Side View with Dimensions

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 as shown

in Figure 12. The module slots are numbered 1 to 4, left to right.
