Three-phase AC cabling for the USA (60 Hz)
Each three-phase HP Disk Array XP1024 DKU has two main disconnect
devices (two main breakers for dual power lines) so that AC power to the
unit can be supplied from separate power distribution panels with two
power-supply cords.
Warning
Trained service personnel should be present whenever the disk array is
being connected to a new power source for the first time. Incorrect power
connections can cause equipment damage and possible injury or death to
personnel.
