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-9214 included with the NI 9214 to ensure that the terminals are not

accessible.

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 Vrms, Measurement Category II
