If you have a processor with a power supply, and do not need
additional current for your I/O modules, skip this step. If you need
additional current, use an ac powered supply because we recommend
that you use the same input voltage source for two paralleled power
supplies.
ATTENTION: Do not parallel a 1771-P5 power supply and
a processor with a power supply because of power-up and
power-down timing difference.
