Seismic Anchoring Preparation

Note: If seismic protection is required in your area, read this section. If not, proceed to

“Operating Environment” on page 12. However, if you install a 352 mm (13.85 in) enclosure,

it must always be equipped with the enclosure stabilizing bracket for enhanced stability (not

necessary to bolt the enclosure stabilizing bracket to the floor in non-seismic areas).

Drill floor holes for seismic anchoring

Note: If your UPS installation requires seismic protection, the UPS installation must be

anchored to the floor, re-using the brackets that also secured the enclosure to the pallets when

shipped. For easy determination of where to drill the holes, refer to the applicable drawings

below indicating hole positions and size.
