Electrical Specifications; Ac Line Voltage Requirements - HP StorageWorks XP10000 Disk Array Site Prep Manual

3 Electrical specifications
The detailed electrical specifications in this chapter are provided to help your site
electrician perform any necessary electrical work related to site prep.

AC line voltage requirements

The AC power requirements are essentially the same for both the primary and the
second racks. Each rack operates on 200 VAC nominal, 20 amps, 50 or 60 Hz,
single-phase power. An independent branch circuit and circuit breaker is required
for each AC input power cord.
The following table lists specific power requirements.

Recommended circuit breakers
Number of circuit breakers
Important notes:
208 VAC is 60 Hz only. Rated line current per power cord is the maximum allowable
current under worst case conditions. This value applies to each individual power cord
and is specified in RMS amperes. For the second rack, four power cords and circuit
breakers are strongly recommended even though a minimum configuration containing
only one expansion disk chassis requires only 2 power cords and 2 circuit breakers. If
a second expansion disk chassis is added to the second rack, four power cords and
four circuit breakers are required.
