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. See 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. Pollution degrees are listed below:
•
Pollution Degree 1—No pollution or only dry, nonconductive
pollution occurs. The pollution has no effect.
