You can connect hazardous voltages only to the NI 9472/9474 with 
screw terminal. Do not connect hazardous voltages to the NI 9472 
with DSUB. 

If hazardous voltages are connected to the module, take the 
following precautions. A hazardous voltage is a voltage greater 
than 42.4 V

pk

 or 60 VDC to earth ground.

Ensure that hazardous voltage wiring is 

performed only by qualified personnel adhering to local 
electrical standards.

Do not mix hazardous voltage circuits and 

human-accessible circuits on the same module.

Make sure that devices and circuits connected to 

the module are properly insulated from human contact.

When module terminals are hazardous voltage 

LIVE (>42.4 V

pk

/60 VDC), you must ensure that devices
