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
or 60 V

), it may require a safety earth-ground connection wire. Refer to

dc

, 42.4 Vpk,

rms

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.

voltage. 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.

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

3

Measurement Category is also referred to as Installation Category.

4

MAINS is defined as the (hazardous live) electrical supply system to which equipment is designed to be connected for the
purpose of powering the equipment. Suitably rated measuring circuits may be connected to the MAINS for measuring
purposes.
