Description
Specification
Each chassis power supply should have its own dedicated, fused-branch circuit:
•
North America
—
20 A.
•
International
—
Circuits sized to local and national codes.
•
All AC power supply inputs are fully isolated:
◦
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.
