Special Conditions for Hazardous Locations Use
in Europe
Some chassis have been evaluated as Ex nA nL IIC T4 equipment under
DEMKO Certificate No. 07 ATEX 0626664X. Each such chassis is marked
II 3G and is suitable for use in Zone 2 hazardous locations, in ambient
temperatures of –20 °C ≤Ta ≤ 55 °C.
Special Conditions for Marine Applications
Some chassis are Lloyd’s Register (LR) Type Approved for marine
applications. To verify Lloyd’s Register certification, visit ni.com/
certification and search for the LR certificate, or look for the Lloyd’s
Register mark on the chassis.

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.
