Installing seismic bracing

NN43021-310 Standard 02.01
Installing earthquake bracing
Universal equipment modules (UEM) are designed to withstand most
earthquakes. However, to provide earthquake security, two kits must be
installed for each column—a bracing kit provides vertical support to each
column of modules and an anchor kit secures each pedestal to the floor.
Each CS 1000M Large System and Meridian 1 Large System has been
certified to meet two of the most stringent seismic specifications for concrete
floor mounting: BELLCORE and CALIFORNIA OSHPD:
• BELLCORE is intended for central-office equipment installations. The
requirements are defined in the Network Equipment Building System
(NEBS), General Equipment Requirements, TR-EOP-000063 issued by
Bell Communications Research (BELLCORE). Each Large System has
been certified to meet the maximum severity (Zone 4).
• CALIFORNIA OSHPD, as part of the California building code, requires
the anchorage of all fixed hospital equipment to be approved by the
California Office of Statewide Health Planning and Development
(OSHPD), Division of Facilities Development and Financing. Each
Large System has been certified for such installations under anchorage
pre-approval number R-0233.

1 "Selecting the kit" on
2 "Drilling concrete floors" on
3 "Installing Kit A and Kit B anchor plates" on
