HP StorageWorks Disk Array XP1024: Site Preparation Guide (A7906-96013, July 2005)

44 HP StorageWorks Disk Array XP1024: Site Preparation Guide
The table below lists the basic AC power requirements for 60-amp,
three-phase, R2, L1, and L2 XP1024 DKUs. Unlike the first DKU (R1),
DKUs R2, L1, and L2 do not provide AC power to the DKC.

1. 60 Hz only.
2. 30-amp breakers are adequate at 380, 400, and 415 VAC, because the
current drawn at these voltages is considerably less than at the lower
voltages.
