Safety Information
Caution
The following paragraphs contain important
safety information you
must
follow when installing and
operating the NI smart camera.
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. 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.
