What You Need to Start Using the CompactRIO
System
After you install the CompactRIO chassis, controller, and C Series modules, you need the
following things to start using the CompactRIO system:
• Windows computer with LabVIEW and NI-RIO software installed
•ni.com/gettingstarted—learn how to install, set up, and configure your CompactRIO
hardware and learn the basics of LabVIEW software.
•LabVIEW Help—access information about LabVIEW programming concepts, step-by-
step instructions for using LabVIEW, and reference information about LabVIEW VIs,
functions, palettes, menus, tools, properties, methods, events, dialog boxes, and so on.
Installing the Controller on the Chassis
Complete the following steps to install the controller on the chassis.
1. Make sure that no power is connected to the controller or the chassis.
2. Align the controller with the chassis.

3. Slide the controller onto the controller slot on the chassis. Press firmly to ensure the
chassis connector and the controller connector are mated.
4. Using a number 2 Phillips screwdriver, tighten the two captive screws on the front of the
controller to 1.3 N · m (11.5 lb · in.) of torque.
Mounting the CompactRIO Reconfigurable
Embedded Chassis
You can mount the chassis on a panel, on a 35 mm DIN rail, on a rack, in an enclosure, or on a
desktop. Use the DIN rail mounting method if you already have a DIN rail configuration or if
you need to be able to quickly remove the CompactRIO chassis. Use the panel mount method
for high shock and vibration applications. Use an enclosure for harsh, dirty, or wet
environments.
Caution If the ambient temperature is 56 °C to 70 °C, you must mount the chassis
on a thermally conductive material. For information about how mounting
NI cRIO-9111/9112/9113/9114/9116/9118 | © National Instruments | 5

configuration can affect the accuracy of C Series modules, go to ni.com/info and
enter the info code rdcriotemp. Measure the ambient temperature at each side of
the CompactRIO system, 63.5 mm (2.5 in.) from the side, and 25.4 mm (1 in.) from
the rear cover of the system.
Go to ni.com/info and enter the info code criomounting to learn more about the different
mounting methods for CompactRIO.
Before using any of the 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 Before you mount the chassis, make sure that I/O modules are not in the
chassis.
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.
Go to ni.com/info and enter rdcrioconn to find the minimum cabling clearance for
C Series modules with other connector types.
Note Go to ni.com/dimensions for more information about the dimensions of the
CompactRIO system, including detailed dimensional drawings.
The following figures show the dimensions of the four- and eight-slot chassis.

Mounting the Chassis on a Panel
Complete the following steps to mount the chassis on a panel.
1. Align the chassis on the panel.
2. Bolt or screw the chassis to the panel using two M4 or number 10 panhead screws. NI
does not provide the screws with the chassis.

Figure 8. Mounting an Eight-Slot Chassis on a Panel
Caution If you are using the NI 9904/9905 panel mount kit, you must use the
M4 × 22 screws included in the kit to attach the chassis to the kit.
Caution Remove the I/O modules from the chassis before removing the
chassis from the panel.
Mounting the Chassis on a DIN Rail
You can order the NI 9912 DIN rail mount kit if you want to mount a four-slot CompactRIO
chassis on a DIN rail, or the NI 9915 DIN rail mount kit if you want to mount an eight-slot
CompactRIO 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 × 22 screws. The screws are included in the DIN rail mount kit.
