1.11 Displacement
The horizontal displacement of the top of the equipment is listed in Table H. The
horizontal displacements given in Table H are plus/minus values. The equipment must
be at the minimum distance listed in Table H to avoid contact with other stationary
objects during a seismic event.
Table H. 9395 Unit Seismic Displacement Requirements
Type Front to Back Side to Side
275 kVA UPS 74 mm 49 mm
275 kVA UPS and FI-UPM 74 mm 49 mm
550 kVA UPS 39 mm 44 mm
550 kVA UPS and FI-UPM 39 mm 49 mm
825 kVA UPS 44 mm 44 mm
825 kVA UPS (2X-UPM) 74 mm 49 mm
825 kVA UPS (2X-UPM and FI-UPM) 74 mm 49 mm
1100 kVA or 825 kVA and FI-UPM 44 mm 49 mm
225-550 kVA MBM 36 mm 36 mm
MBM and 275 kVA UPS 74 mm 49 mm
MBM and 550 kVA UPS 39 mm 44 mm
Consideration must be given to attachments (conduits, bus duct, etc.) made to the
top of the equipment. Attachments must have provisions to accommodate the
displacement of the equipment indicated in Table H. Entry from the bottom of the
equipment eliminates the need for accommodating this motion for attachments.
1.12 Center of Gravity
For seismic calculations, the center of gravity can be approximated using the
dimensions in Table I with respect to the left side bracket's front mounting hole
(x,y,z origin).
