Power Requirements

WARNING: To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that provides power
to the rack. Consult the electrical authority having jurisdiction over your
facility wiring and installation requirements.
IMPORTANT: Because of the 100 to 240 VAC electrical rating of each power supply, some
local electrical authorities may require either one 15-Ampere circuit for each power supply or
one 20-Ampere circuit for both power supplies.
•
The power load needs to be balanced between available AC supply
branch circuits.
•
The overall system AC current load must not exceed 80 percent of the branch
circuit AC current rating.
