Description
Each chassis power supply should have its own
dedicated, fused-branch circuit:
For North America—20 A
•
For 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.
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.
