Safety Information
Caution
The following paragraphs contain important safety information you
must
follow
when installing and operating the device.
Do
not
operate the module in a manner not specified in this document.
Misuse of the module can result in a hazard. You can compromise the safety
protection built into the module if the module is damaged in any way. If the
module is damaged, return it to National Instruments (NI) for repair.
Do
not
substitute parts or modify the module except as described in this
document. Use the module 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 module.
Do
not
operate the module in an explosive atmosphere or where there may
be flammable gases or fumes. If you must operate the module in such an
environment, it must be in a suitably rated enclosure.
If you need to clean the module, use a soft, nonmetallic brush. Make sure
that the module is completely dry and free from contaminants before
returning it to service.
Operate the module 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 module is rated. Do
not
exceed the maximum ratings for the module.
Do not install wiring while the module is live with electrical signals. Do not
remove or add connector blocks when power is connected to the system.
