950 W AC-Input Power Supply Specifications (continued)
Description
Each chassis power supply should have its own dedicated, fused-branch
circuit:

950 W AC-Input and DC-Input Power Supplies
Source AC can be out of phase between multiple power supplies
in the same chassis, which means that PS1 can be operating
from phase A and PS2 can be operating from phase B.
For high-line operation, the power supply operates with the hot
conductor wired to a source AC phase and the neutral conductor
wired either to ground or to another source AC phase as long as
the net input voltage is in the range of 170 to 264 VAC.
Source AC can be out of phase between AC inputs on power
supplies that are equipped with multiple AC inputs, which
means that power cord 1 can be plugged into phase A and
power cord 2 can be plugged into phase B.
