Hitachi G1500 - System Storage Requirements; Grounding; Power Connection

The weight for a fully congured 2-controller, 6-rack storage system can reach 6,146
pounds / 2,917 kilogr
ams. The e
xact weight of the equipment depends on the stor

system
conguration. The following table provides weights of typical system
congurations.

System storage requirements
If the equipment must be stored after delivery and prior to installation, the storage
location must meet the storage environmental requirements for the storage system. See
Environmental specications (on page 143) for mor
e details.
Grounding
The site and site equipment must meet the follo
wing gr
ounding r
equirements:
■
An insulated grounding conductor that is identical in size and insulation material and
thickness to the grounded and ungrounded branch-circuit supply conductors. It must
be green, with or without yellow stripes, and must be installed as a part of the branch
circuit that supplies the unit or system.
■
Connect the grounding conductor to earth ground at the service equipment or other
acceptable building earth ground. For a high rise steel-frame structure, this can be the
steel frame.
■
The receptacles in the vicinity of the unit or system must include a ground
connection. The grounding conductors serving these receptacles must be connected
to earth ground at the service equipment or other acceptable building earth ground.
Power connection
The AC power input for the storage system has a duplex PDU structure that allows the
rack-installed equipment to remain powered on if power is removed from one of the two
power distribution panels (PDP).
For more information, see
Electrical specications (on page 140) and Power distribution
units for Hitachi Universal V2 Rack (on page 153) .
Note: Site po
wer can be connected to the PDUs at either the top or bottom of
the r
acks.
