Safety Information

Caution The following paragraphs contain important safety information you must follow when

installing and operating the device.

Do not operate the device in a manner not specified in the documentation. Misuse of the device may

result in a hazard and may compromise the safety protection built into the device. If the device is

damaged, turn it off and do not use it until service-trained personnel can check its safety. If necessary,

return the device to National Instruments for repair.

Keep away from live circuits. Do not remove equipment covers or shields unless you are trained to do

so. If signal wires are connected to the device, hazardous voltages can exist even when the equipment is

turned off. To avoid a shock hazard, do not perform procedures involving cover or shield removal unless

you are qualified to do so. Disconnect all field power prior to removing covers or shields.

If the device is rated for use with hazardous voltages (>30 Vrms, 42.4 Vpk, or 60 Vdc), it may require a

safety earth-ground connection wire. Refer to the device specifications for maximum voltage ratings.

Because of the danger of introducing additional hazards, do not install unauthorized parts or modify the

device. Use the device only with the chassis, modules, accessories, and cables specified in the

installation instructions. All covers and filler panels must be installed while operating the device.

Do not operate the device in an explosive atmosphere or where flammable gases or fumes may be

present. Operate the device only at or below the pollution degree stated in the specifications. Pollution

consists of any foreign matter—solid, liquid, or gas—that may reduce dielectric strength or surface

resistivity. The following is a description of pollution degrees.

• Pollution Degree 1—No pollution or only dry, nonconductive pollution occurs. The pollution has

no effect.

• Pollution Degree 2—Normally only nonconductive pollution occurs. Occasionally, nonconductive

pollution becomes conductive because of condensation.

• Pollution Degree 3—Conductive pollution or dry, nonconductive pollution occurs. Nonconductive

pollution becomes conductive because of condensation.

Clean the device and accessories by brushing off light dust with a soft, nonmetallic brush. Remove other

contaminants with a stiff, nonmetallic brush. The unit must be completely dry and free from

contaminants before returning it to service.

Yo u must insulate signal connections for the maximum voltage for which the device is rated. Do not

exceed the maximum ratings for the device. Remove power from signal lines before connection to or

disconnection from the device.

Caution National Instruments measurement products may be classified as either Measurement

Category I or II. Operate products at or below the Measurement Category level specified in the

hardware specifications.

Measurement Category1: Measurement circuits are subjected to working voltages2and transient

stresses (overvoltage) from the circuit to which they are connected during measurement or test.

Measurement Category establishes standardized impulse withstand voltage levels that commonly occur

1 Measurement Categories as defined in electrical safety standard IEC 61010-1.

2 Working voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.

in electrical distribution systems. The following is a description of Measurement (Installation1)

Categories:

• Measurement Category I is for measurements performed on circuits not directly connected to the

electrical distribution system referred to as MAINS2voltage. This category is for measurements of

voltages from specially protected secondary circuits. Such voltage measurements include signal

levels, special equipment, limited-energy parts of equipment, circuits powered by regulated

low-voltage sources, and electronics.

• Measurement Category II is for measurements performed on circuits directly connected to the

electrical distribution system. This category refers to local-level electrical distribution, such as that

provided by a standard wall outlet (e.g., 115 V for U.S. or 230 V for Europe). Examples of

Measurement Category II are measurements performed on household appliances, portable tools,

and similar products.

• Measurement Category III is for measurements performed in the building installation at the

distribution level. This category refers to measurements on hard-wired equipment such as

equipment in fixed installations, distribution boards, and circuit breakers. Other examples are

wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation,

and stationary motors with permanent connections to fixed installations.

• Measurement Category IV is for measurements performed at the primary electrical supply

installation (<1,000 V). Examples include electricity meters and measurements on primary

overcurrent protection devices and on ripple control units.

Unpacking

The NI 8234 ships in an antistatic package to prevent electrostatic discharge from damaging device

components. To avoid such damage in handling the device, take the following precautions:

1. Ground yourself using a grounding strap or by touching a grounded object, such as the computer

chassis.

2. Touch the antistatic package to a metal part of the chassis before removing the device from the

package.

Caution Never touch the exposed pins of connectors.

3. Remove the device from the package and inspect the device for loose components or any sign of

damage. Notify NI if the device appears damaged in any way. Do not install a damaged device into

the PXIe/cPCIe chassis.
