8700 W AC-Input Power Supply Specifications (continued)
Specification
AC-input current
AC-input frequency
Branch circuit requirement
Description
16 A each input
50/60 Hz (nominal) (±3% for full range)
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.
