Proper mounting of the equipment is the single most important factor in withstanding a seismic event. The
foundation must be level and continuous under the entire assembly. The foundation must be designed to
withstand the reaction loads imposed on it by the equipment during a seismic event. At a minimum, the
foundation must be designed to accommodate the tensile strength of the hardware indicated in
Table 1 .
The anchoring system should be put in place prior to equipment installation to reduce effort associated with
anchoring. Welding to embedded steel members is acceptable provided the strength of the welds is
comparable to the mounting bolts.
The user is responsible for compliance with all local seismic codes.
N NO OT TE E Anchoring hardware is not provided with Eaton seismic mounting kits because the type
of hardware is dependant on the foundation construction and composition.

The horizontal displacement of the top of the equipment is listed in Table 2 . The horizontal displacements given
in the table are plus/minus values. The equipment must be at the minimum distance listed in the table to avoid
contact with other stationary objects during a seismic event.
