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.

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.

Electromagnetic Compatibility Guidelines

This product was tested and complies with the regulatory requirements and limits

for electromagnetic compatibility (EMC) stated in the product specifications. These

requirements and limits provide reasonable protection against harmful interference

when the product is operated in the intended operational electromagnetic

environment.

This product is intended for use in industrial locations. However, harmful

interference may occur in some installations, when the product is connected to a

peripheral device or test object, or if the product is used in residential or

commercial areas. To minimize interference with radio and television reception and

prevent unacceptable performance degradation, install and use this product in strict

accordance with the instructions in the product documentation.

Furthermore, any changes or modifications to the product not expressly approved

by National Instruments could void your authority to operate it under your local

regulatory rules.

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 NI 9149 meets the following

specifications.

Operating temperature (IEC 60068-2-1, IEC 60068-2-2) -40 °C to 70 °C

Operating humidity (IEC 60068-2-78) 10% RH to 90% RH, noncondensing

Pollution Degree 2

Maximum altitude 5,000 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.

ni.com

NI-9149 Getting Started

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 NI 9149 kit.

Installing Soware on the Host Computer

Before using the NI 9149, you must install the following application soware and

device drivers on the host computer in this order:

1. LabVIEW 2014 SP1 or later

2. LabVIEW FPGA Module 2014 SP1 or later

3. NI-RIO Device Drivers 14.5 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 NI 9149, LabVIEW FPGA Module is

required.

Installing C Series Modules

Complete the following steps to install a C Series module.

NI-9149 Getting Started

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 NI 9149 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 NI 9149. If the system is in a nonhazardous

location, the NI 9149 can be powered on when you remove modules.

Connecting the NI 9149

The NI 9149 has the following connectors, LEDs, and buttons.

Connecting the NI 9149 to Ground

You must connect the NI 9149 grounding terminal to the grounding electrode

system of the facility.
