Three-Phase Ac Cabling For Usa - HP StorageWorks XP128 Installation Manual

Three-phase AC cabling for USA

Connecting the external power supply cord
Preparing for installation
Each three-phase HP Disk Array XP128 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.
Trained service personnel should be present whenever the disk array is
being connected to a new power source for the first time.
Three-phase HP Disk Array XP128s are factory-configured for 30-amp
power.
30-amp, three-phase power
When the disk array uses 30-amp, three-phase input power, HP Disk Array
XP128s have two power cords as shown in the figure below. If one power
source malfunctions, the other power source assumes the total load,
providing uninterrupted operation. HP recommends that each power cord
have a separate electrical circuit as its source in case of a circuit failure.
Each power-supply cord is supplied with an attachment plug type
Russellstoll 3760PDG. Be sure to install Russellstoll 3934 (alternate,
9C34U0) or 3754 (alternate, 39R34U0W) socket receptacles between the
power distribution panel of the building and the attachment plugs for the
XP128.
