Caution The protection provided by the NI cRIO-9030 controller can be impaired
if it is used in a manner not described in this document.
Safety Voltages
Connect only voltages that are below these limits.
V1 terminal to C terminal ................................. 30 VDC max, Measurement Category I
V2 terminal to C terminal ................................. 30 VDC max, Measurement Category I
Chassis ground to C terminal ........................... 30 VDC max, Measurement Category I
Measurement Category I is for measurements performed on circuits not directly connected to the
electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live
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.
