The cRIO-9081 is suitable for use in Class I, Division 2, Groups A, B, C, D, T4
hazardous locations; Class I, Zone 2, AEx nA IIC T4 Gc and Ex nA IIC T4 Gc hazardous
locations; and nonhazardous locations only. Follow these guidelines if you are
installing the cRIO-9081 in a potentially explosive environment. Not following these
guidelines may result in serious injury or death.
Caution Do not disconnect the power supply wires and connectors from
the controller unless power has been switched o.
Caution Do not disconnect I/O-side wires or connectors unless power has
been switched o or the area is known to be nonhazardous.
Caution Do not remove modules unless power has been switched o or
the area is known to be nonhazardous.
Caution Substitution of components may impair suitability for Class I,
Division 2, or Zone 2.
Caution The system must be installed in an enclosure certified for the
intended hazardous (classified) location, having a tool secured cover/door,
where a minimum protection of at least IP54 is provided.
Special Conditions for Hazardous Locations Use in Europe and
Internationally
The cRIO-9081 has been evaluated as Ex nA IIC T4 Gc equipment under
DEMKO 07ATEX 0626664X and is IECEx UL 14.0089X certified. Each device is marked
II 3G and is suitable for use in Zone 2 hazardous locations, in ambient
temperatures of 0 °C ≤ Ta ≤ 55 °C.

Caution Transient protection shall be provided that is set at a level not
exceeding 140% of the peak rated voltage value of 85 V at the supply
terminals to the equipment.
Caution The system shall only be used in an area of not more than
Pollution Degree 2, as defined in IEC/EN 60664-1.
Caution The system shall be mounted in an ATEX/IECEx-certified
enclosure with a minimum ingress protection rating of at least IP54 as
defined in IEC/EN 60079-15.
Caution The enclosure must have a door or cover accessible only by the
use of a tool.

Special Conditions for Marine Applications
Some products are approved for marine (shipboard) applications. To verify marine
approval certification for a product, visit ni.com/product-certifications, search by
model number, and click the appropriate link.
Notice In order to meet the EMC requirements for marine applications,
install the product in a shielded enclosure with shielded and/or filtered
power and input/output ports. In addition, take precautions when
designing, selecting, and installing measurement probes and cables to
ensure that the desired EMC performance is attained.
Preparing the Environment
Ensure that the environment in which you are using the cRIO-9081 meets the
following specifications.
Operating temperature (IEC 60068-2-1, IEC 60068-2-2) 0 °C to 55 °C
Operating humidity (IEC 60068-2-78) 10% RH to 90% RH, noncondensing
Pollution Degree 2
Maximum altitude 2,000 m
Indoor use only.
Note Refer to the device specifications on ni.com/manuals for complete
specifications.
Unpacking the Kit
Notice To prevent electrostatic discharge (ESD) from damaging the
device, ground yourself using a grounding strap or by holding a grounded
object, such as your computer chassis.

1. Touch the antistatic package to a metal part of the computer chassis.
2. Remove the device from the package and inspect the device for loose
components or any other sign of damage.
Notice Never touch the exposed pins of connectors.
Note Do not install a device if it appears damaged in any way.
3. Unpack any other items and documentation from the kit.
Store the device in the antistatic package when the device is not in use.
Verifying the Kit Contents
Verify that the following items are included in the cRIO-9081 kit.
Installing Soware on the Host Computer
Before using the cRIO-9081, you must install the following application soware and
device drivers on the host computer in this order:
1. LabVIEW 2011 or later
2. LabVIEW Real-Time Module 2011 or later
3. LabVIEW FPGA Module 2011 or later[1]
4. NI CompactRIO Device Drivers 4.0 or later
For minimum soware support information, visit ni.com/info and enter the Info
Code swsupport.
1 LabVIEW FPGA Module is not required when using Scan Interface mode. To
program the user-accessible FPGA on the cRIO-9081, LabVIEW FPGA Module is
required.
Installing C Series Modules
Complete the following steps to install a C Series module.

NI cRIO-9081
1. Verify that power is not connected to the I/O connector(s) on the C Series
module. If the system is in a nonhazardous location, the cRIO-9081 can be
powered on when you install modules.
2. Press the latches on the C Series module.
3. Align the C Series module with a slot and seat it in the slot until the latches
lock in place.
Removing C Series Modules
Verify that power is not connected to the I/O connector(s) on the C Series module
before you remove a module from the cRIO-9081. If the system is in a nonhazardous
location, the cRIO-9081 can be powered on when you remove modules.
Connecting the cRIO-9081
The cRIO-9081 has the following connectors, LEDs, and buttons.
Connecting the cRIO-9081 to Ground
You must connect the cRIO-9081 grounding terminal to the grounding electrode
system of the facility.

What to Use
■Ring lug
■Wire, 1.6 mm2 (14 AWG) or larger
■Screwdriver, Phillips #2
What to Do
Complete the following steps to ground the cRIO-9081.
1. Attach the ring lug to the wire.
2. Remove the grounding screw from the grounding terminal on the cRIO-9081.
3. Attach the ring lug to the grounding terminal.
4. Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
5. Attach the other end of the wire to the grounding electrode system of your
facility using a method that is appropriate for your application.
Caution If you use shielded cabling to connect to a C Series module with
a plastic connector, you must attach the cable shield to the chassis
grounding terminal using 1.6 mm2 (14 AWG) or larger wire. Attach a ring
lug to the wire and attach the wire to the chassis grounding terminal.
Solder the other end of the wire to the cable shield. Use shorter wire for
better EMC performance.
For more information about ground connections, visit ni.com/info and enter the
Info Code emcground.
Connecting the cRIO-9081 to Power
The cRIO-9081 requires a 9 V to 30 V external power supply. The cRIO-9081 filters
and regulates the supplied power and provides power for the C Series modules. The
cRIO-9081 has a primary power input, V1, and a secondary power input, V2.
