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.
Special Conditions for Hazardous Locations Use in Europe and
Internationally
The NI 9146 has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO
Certificate No. 07 ATEX 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 -40 °C ≤ Ta ≤ 70 °C.

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.

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.

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

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.).
