Grounding - HP P9000 Manual

Table 9 P9500 Electrical specifications - three phase current
Item
Power requirements
Power consumption .
NOTE: The power
consumption of the system is
the same whether it uses
single phase or three phase
power. The difference is that
each branch of the three
phase input power draws
less current than the single
phase conductors.
Power consumption, system
in standby
NOTE: Site power can be connected to the PDUs at either the top or bottom of the racks.

Grounding

The site and equipment must meet all of the following three conditions of installation for grounding.
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.
The grounding conductor mentioned above should be grounded to earth at the service
equipment or other acceptable building earth ground such as the building frame in the case
of a high rise steel-frame structure.
The attachment-plug receptacles in the vicinity of the unit or system must include a ground .
The grounding conductors serving these receptacles must be connected to earth ground at the
service equipment or other acceptable building earth ground such as the building frame in
the case of a high-rise steel-frame structure.
