Caution
Do not mix hazardous voltage circuits and human-accessible
circuits on the same module.
Caution
Ensure that devices and circuits connected to the module are
properly insulated from human contact.
Caution
When module terminals are hazardous voltage LIVE (>42.4 V
pk
/
60 V DC), you must ensure that devices and circuits connected to the
module are properly insulated from human contact. You must use the
TB-9214 included with the NI 9214 to ensure that the terminals are not
accessible.
Note
The TB-9214 contains a plastic insert to prevent accidental wire
contact with the metal enclosure.
Safety Voltages
Connect only voltages that are within the following limits:
Between any two terminals
±30 V maximum
Isolation
Channel-to-channel
None
Channel-to-earth ground
Continuous
250 V RMS, Measurement Category II
Withstand
2,300 V RMS, verified by a 5 s dielectric withstand test
Safety Guidelines for Hazardous Locations
The NI-9214 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 Gc and Ex nA IIC T4 Gc hazardous locations;
and nonhazardous locations only. Follow these guidelines if you are installing the
