Safety Guidelines for Hazardous Voltages

If hazardous voltages are connected to the module, take the following
precautions. A hazardous voltage is a voltage greater than 42.4 Vpk 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 the NI WLS/ENET-9163 carrier and circuits connected to the
module are properly insulated from human contact.
Caution The NI WLS/ENET-9163 carriers provide no isolation, but some modules offer
isolation. Follow the safety guidelines for each module when using hazardous voltage.
