NI-9146 Safety, Environmental, and Regulatory Information

Safety Guidelines for Hazardous Locations

The NI 9146 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 and Ex nA IIC T4 hazardous locations;

and nonhazardous locations only. Follow these guidelines if you are installing the

NI 9146 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.

Caution For Division 2 and Zone 2 applications, install the system in an

enclosure rated to at least IP54 as defined by IEC/EN 60079-15.

NI-9146 Safety, Environmental, and Regulatory Information

Caution You must make sure that transient disturbances do not exceed

140% of the rated voltage.

Caution The system shall only be used in an area of not more than

Pollution Degree 2, as defined in IEC 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.

NI-9146 Safety, Environmental, and Regulatory Information

Special Conditions for Marine Applications

Some products are Lloyd’s Register (LR) Type Approved for marine (shipboard)

applications. To verify Lloyd’s Register certification for a product, visit ni.com/

certification and search for the LR certificate, or look for the Lloyd’s Register mark

on the product.

Caution 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.

Unpacking the Kit

Caution 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.

Caution 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.

What You Need to Install the NI 9146

■NI 9146 Ethernet Expansion Chassis

■NI-RIO Soware DVD

■C Series I/O modules

■DIN rail mount kit (for DIN rail mounting only)

■Panel mount kit (for panel mounting only)

■Two M4 or number 8 flathead screws (for mounting the chassis without one

of the listed mounting kits)

■A number 2 Phillips screwdriver

■Power supply

■Ethernet cable

Note Visit ni.com/info and enter the Info Code rdsowareversion to

determine which soware you need to use the NI 9146.

Mounting the Chassis

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 70 °C. The following figure shows the chassis 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 aect the typical accuracy of modules in

the chassis.

NI-9146 Safety, Environmental, and Regulatory Information

Note For information about how dierent 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.

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.

The following sections give 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 aer 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 Panel

You can use the NI 9904 panel mount kit to mount the NI 9146 on a flat surface.

Complete the following steps to mount the NI 9146 on a panel.

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

screwdriver and two M4 × 25 screws. National Instruments provides these

NI-9146 Safety, Environmental, and Regulatory Information

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.).
