Figure 1-1.  Installing the NI 4050 and Cables

The test probes connect to the NI 4050 accessory cable via shrouded 
banana jacks. The shrouds around the banana jacks prevent you from 
contacting potentially hazardous voltages connected to the test probes. 
You  can also connect the cable to standard, unshrouded banana jack probes 
or accessories; however, use unshrouded probes or accessories only when 
the voltages are less than 30 V

rms

 or 42 V

pk-to-pk

.

To prevent possible safety hazards, the maximum voltage between either of the 

inputs and the ground of the computer should never exceed ±250 VDC or 250 V
