Pre-Installation System Requirements
4-4. Seismic Requirements
For each unit, the unit mass and the position of the center of gravity is provided in
, to allow compliance with local codes or regulations.
Sites that require seismic anchoring must have a site architect and engineer review the response spec-
tra and/or Uniform Builders Code (UBC) for their location.
4-4-1.
X-Floor Requirements When Using provided Floor Anchors
The maximum load pull tension per provided anchor was calculated assuming:
•
Maximum bolt load pull tension at each bolt, refer to
.
•
Anchors installed to the required minimum floor thickness, refer to
4-4-2.
X-Pan Type Floor Construction Requirement
For Pan type floor construction, steel channels must be designed by a local structural engineer or archi-
tect to span floor joists.
4-4-3.
Generator Cabinet
In seismic areas, provision must be made for securing the Generator to the floor, or provision must be
made to secure it in place. For example, encircle the unit with a nylon belt secured to wall anchors.
4-4-4.
Independent Radiation Shield
In seismic areas, if the optional independent radiation shield is present, it must be anchored to the floor,
or provision must be made to secure it in place. For example, encircle the unit with a nylon belt secured
to wall anchors.
4-4-5.
Gantry
Two additional anchoring holes exist to improve the anchoring: refer to
.

ELECTRICAL REQUIREMENTS
5-1. CERTIFIED ELECTRICAL CONTRACTOR STATEMENT
! Notice:
All electrical installations that are preliminary to positioning of the equipment at the site prepared
for the equipment must be performed by licensed electrical contractors. In addition, electrical feeds
into the Power Distribution Unit must be performed by licensed electrical contractors. Other con-
nections between pieces of electrical equipment, calibrations, and testing must be performed by
qualified GE Medical personnel. The products involved (and the accompanying electrical installa-
tions) are highly sophisticated, and special engineering competence is required. In performing all
electrical work on these products, GE will use its own specially trained Field Engineers. All of GE
electrical work on these products will comply with the requirements of the applicable electrical
codes.
The purchaser of GE equipment must only utilize qualified personnel to perform electrical servic-
ing on the equipment. That is GE Field Engineers, personnel of third-party service companies
with equivalent training, or licensed electricians.
