Ac Connections - HP StorageWorks XP10000 Site Preparation Manual

AC connections

Caution
48
The disk array primary rack has four separate connections to 200 VAC,
single-phase, 20-amp power.
The second rack has two connections to AC power in the minimum
configuration (four recommended) and four connections to AC power in
the maximum configuration. Power requirements are 200 VAC, single-
phase, 20-Amps.
When receptacles are used to connect disk array components to AC power,
they must include a dedicated ground connection that is insulated from the
receptacle. It is important that the receptacle box be grounded with an
additional ground connection that is separate from the dedicated ground.
The additional ground can be hard conduit.
Specific AC power cords and plugs are available to suit the power
requirements and receptacles in your location. You can specify the cords
and plugs you need when you order the HP XP10000 disk array. You are
responsible for having the correct plugs and receptacles installed by an
electrician in compliance with local electrical requirements and practices.
When installing the receptacles, the electrician must ensure that each
receptacle has its own neutral (if required) and ground. Using the same
neutral/ground for more than one circuit causes voltage loss and heat
problems and can create a fire hazard. A shared neutral conductor that
fails open-circuit can cause overvoltage damage to equipment.
See Appendix A for specific power requirements as well as plug and
receptacle part numbers and ordering information.
