I am trying to operate a compact-RIO 9054 at elevated ground potentials (150kV+). I have configured the system as shown in the schematic. I however have some question on the operation of the crio.
1. Is this safe to operate (in terms of the hardware)? I have had shorts between the casing and the PCB at high potentials (~20kV) causing equipment failure.
2. What is the highest operating voltage of a CRIO unit? Can apply high floating voltages if the -VCC is tied to the floating ground?
