Hazardous Voltage
This icon denotes a warning advising you to take
precautions to avoid electrical shock.
Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the device, take the following precautions. A
hazardous voltage is a voltage greater than 42.4 Vpk voltage or 60 VDC to earth
ground.
Caution
Ensure that hazardous voltage wiring is performed only by
qualified personnel adhering to local electrical standards.
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 Vpk/
60 VDC), you must ensure that devices and circuits connected to the
module are properly insulated from human contact. You must use the
TB-9212 included with the NI 9212 to ensure that the terminals are not
accessible.
Note
The TB-9212 with screw terminal contains a plastic insert to prevent
accidental wire contact with the metal enclosure.
Isolation Voltages
