weakest point (typically the center of the panel), without the surface of the panel deflecting more
than a predetermined amount
Rolling load
The load a floor panel can support (without failure) when a wheel of specified diameter and
width is rolled across the panel
Table 6 lists the specification for Tate All Steel 1250 System raised flooring.
Note:
If the specific floor being evaluated or considered is other than a Tate All
Steel 1250 System floor, the specific floor manufacturer must be contacted
to evaluate the floor being used.

Electrical considerations
The HP MCS provides two C20-type AC input connections and ships with two sets of power cords for
connecting to redundant AC power buses, if available. Only one power cord is necessary for
operation. The second cord can be connected to a redundant AC power bus to improve system
availability by protecting against power source failures or accidentally tripped circuit breakers.
Note:
The electrical practices and suggestions in this guide are based on North
American practices. For regions and areas outside North America, local
electrical codes will take precedence over North American electrical codes.
An example would be the recommendation that the protective ground
conductor should be green with yellow stripes. This requirement is a North
American directive and does not override the local code requirements for a
region or areas outside North America.
