8700 W AC-Input Power Supply
5800 W operation 5800 W maximum with the following combinations of
power cords and source AC voltage applied to the
power supply inputs:
• Two AC inputs are connected to high-line
(220 VAC nominal); the third AC input is
connected to low-line (110 VAC nominal).
• Two AC inputs are connected to high-line
(220 VAC nominal); the third AC input is not
connected.
8700 W operation 8700 W maximum with the following combinations of
power cords and source AC voltage applied to the
power supply inputs:
• All three AC inputs are connected to high-line
(220 VAC nominal).
System power dissipation 10,360 W
Branch circuit requirement (AC-input) Each power supply input should have its own
dedicated, fused-branch circuit:
• For North America—20 A
• For International—Circuits should be sized
according to local and national codes
• All Catalyst 6500 series AC-input power supplies
require single-phase source AC.
• All AC power supply inputs are fully isolated. This
means that source AC can be out of phase between
multiple AC inputs on the same power supply or
different AC power supplies that are installed in
the same chassis. For the 8700 W power supply,
this means that power cord 1 can be plugged into
phases A-B, power cord 2 can be plugged into
phases B-C, and power cord 3 can be plugged into
phases C-A, A-B, or B-C.
