Safety Information
The following cautions contain important safety information concerning
hazardous voltages.
Cautions
Do
not
operate the device in an explosive atmosphere or where there may be
flammable gases or fumes.
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 and disconnect all field
power prior to removing covers or shields.
Equipment described in this document must be used in an Installation Category I
1
environment per IEC 60664-1. This category requires local level supply mains-connected
installation.
Do
not
operate damaged equipment. The safety protection features built into this device
can become impaired if the device becomes damaged in any way. If the device is damaged,
turn the device off and do
not
use it until service-trained personnel can check its safety.
If necessary, return the device to National Instruments for service and repair to ensure that
its safety is not compromised.
Do
not
operate this equipment in a manner that contradicts the information specified in this
document. Misuse of this equipment could result in a shock hazard.
Do
not
substitute parts or modify equipment. Because of the danger of introducing
additional hazards, do
not
install unauthorized parts or modify the device. Return the
device to National Instruments for service and repair to ensure that its safety features are
not compromised.
You
must
insulate all of your signal connections to the highest voltage with which the
SCXI-1335 can come in contact.
1
Category I refers to a signal level such as voltages of an isolation transformer secondary on a PWB.
