signals connected to the BNC-2090A before you power off your computer.

Caution

Do 

not

 connect input voltages greater than 42.4 V

pk

/60 VDC to the BNC-2090A. 

The BNC-2090A is not designed for any input voltages greater than 42.4 V

pk

/60 VDC, 

even if a user-installed voltage divider reduces the voltage to within the input range of the 
DAQ device. Input voltages greater than 42.4 V

pk

/60 VDC can damage the BNC-2090A, 

all devices connected to it, and the host computer. Overvoltage can also cause an electric 
shock hazard for the operator. National Instruments is 

not

 liable for damage or injury 

resulting from such misuse.
