Safety Information
The following section contains important safety information that you must 
follow when installing and using the product.
Do not operate the product in a manner not specified in this document. 
Misuse of the product can result in a hazard. You can compromise the 
safety protection built into the product if the product is damaged in any 
way. If the product is damaged, return it to National Instruments for repair.
Do not substitute parts or modify the product except as described in this 
document. Use the product only with the chassis, modules, accessories, and 
cables specified in the installation instructions. You must have all covers 
and filler panels installed during operation of the product.
Do not operate the product in an explosive atmosphere or where there may 
be flammable gases or fumes. If you must operate the product in such an 
environment, it must be in a suitably rated enclosure.
If you need to clean the product, use a soft, nonmetallic brush. The product 
must be completely dry and free from contaminants before you return it to 
service.
Operate the product only at or below Pollution Degree 2. Pollution is 
foreign matter in a solid, liquid, or gaseous state that can reduce dielectric 
strength or surface resistivity. The following is a description of pollution 
degrees:
Pollution Degree 1 means no pollution or only dry, nonconductive 
pollution occurs. The pollution has no influence.
Pollution Degree 2 means that only nonconductive pollution occurs in 
most cases. Occasionally, however, a temporary conductivity caused 
by condensation must be expected.
Pollution Degree 3 means that conductive pollution occurs, or dry, 
nonconductive pollution occurs that becomes conductive due to 
condensation.
You must insulate signal connections for the maximum voltage for which 
the product is rated. Do not exceed the maximum ratings for the product. 
Do not install wiring while the product is live with electrical signals. Do not 
remove or add connector blocks when power is connected to the system. 
Avoid contact between your body and the connector block signal when hot 
swapping modules. Remove power from signal lines before connecting 
them to or disconnecting them from the product.
