Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the device/module, take the following precautions. A
hazardous voltage is a voltage greater than 42.4 V
pk
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 Make sure that chassis and circuits connected to the module are properly
insulated from human contact.
Caution NI 62xx devices and modules provide no isolation.
