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 V

rms

, 42.4 V

pk

, or 60 V

dc

), 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.

You

 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 Category

1

: Measurement circuits are subjected to working voltages

2

 and 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.
