Figure 9 30-amp, three-phase power cords . 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 DDK 115J-AP8508. TIP: DDK115J-AP8508 plug has the same fit and form as the Russellstoll (T&B) 3760PDG plug and is fully compatible with Russellstoll (T&B) connectors. Be sure to install Russellstoll 3934 (alternate, 9C34U0) or 3754 (alternate, 39R34U0W) socket receptacles between the power distribution panel of the building and the power plugs for the unit. The power cords provided with the disk array are non-shielded, type ST or equivalent with four #8 AWG (minimum) conductors terminated at one end with an assembled plug connector. Three-phase AC USA branch circuit requirements To protect the disk array, your building must be wired correctly. Each supply ("hot") conductor must be protected by a short-circuit protective device and by an over current protective device. All protective devices must comply with national standards of the country where the units are to be installed. If a protective device interrupts any supply conductor, it must also interrupt all other supply conductors. Overcurrent protection is not required for the neutral conductor of this unit. Only 50-Hz, three-phase configurations have a neutral conductor. XP24000 three-phase AC cabling for Europe (50 Hz) Each three-phase DKU has two main disconnect devices (two main breakers for dual power lines) so AC power can be supplied from separate power distribution panels with two power supply cords. 50 Electrical specifications for the HP Disk Arrays
