and EDIDS-2412) should be powered by two identical supplies wired in parallel. Power supplies wired in parallel will
create a supply having the same voltage as the individual supplies, but double the current capacity. Please refer to
the power supply documentation for wiring instructions .
Power Wiring Guidelines
NI recommends powering and grounding each component in the system in a star-wiring configuration, such that
each component is wired individually from a single star-point for both positive and negative terminals of the power
supply buses. In contrast, it is not recommended to power the components in a daisy-chain configuration because it
will cause some modules to experience supply voltage fluctuations.
NI recommends using crimped ferrules on all wires entering screw terminal connections.
