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.  
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 Category1: Measurement circuits are subjected to working  
voltages2 and transient stresses (overvoltage) from the circuit to which they  
are connected during measurement or test. Measurement Category

occur 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 MAINS2 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.  
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 8255R 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:  
Ground yourself via a grounding strap or by holding a grounded object,  
such as the computer chassis.  
Touch the antistatic package to a metal part of the computer chassis  
before removing the device from the package.  
Caution Never touch the exposed pins of connectors.
