electrical supply system that powers equipment. This category is
for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special
equipment, limited-energy parts of equipment, circuits powered
by regulated low-voltage sources, and electronics.

Caution

 

Do not connect the NI 9403 to signals or use

for measurements within Measurement Categories II,
III, or IV.

Safety Guidelines for Hazardous Locations

The NI 9403 is suitable for use in Class I, Division 2, Groups A,
B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4
and Ex nA IIC T4 hazardous locations; and nonhazardous
locations only. Follow these guidelines if you are installing the
NI 9403 in a potentially explosive environment. Not following
these guidelines may result in serious injury or death.

Caution

 

Do not disconnect I/O-side wires or

connectors unless power has been switched off or the
area is known to be nonhazardous.
