HORIZONTAL STACKING SHACKLE-STRAP USAGE
Figure 12
Where floor anchoring is required, position
In order to complete stacking of a horizontal single stack refer to Figures 12 to 15 and steps A through C listed below.
NOTE: The use of leveling shims is required when assembling any Absolyte GX system in order to meet seismic requirements. Failure to use the shims to level each module and to fill spaces between tray channels during module assembly will result in the assembly not meeting seismic certification criteria. In extreme cases, stack to stack connectors cannot be installed.
A. Using Section 6.5 and 8.1.3 and the layout/wiring diagram, position the next module on top of first so that channels of each mate with one another. Use drift pins to align channel holes. Make sure channel ends and sides of the upper and lower modules are flush. Remove lifting straps and install M10 serrated flange
bolts and nuts in open holes, finger tight. Use leveling shims to fill gaps between trays. See Figures 13, 14 and 15.
B. At this time, check to see that the first two modules are plumb front to back and side to side using wooden or plastic level together with plywood straight edge. This is to insure proper alignment for module interconnec- tion later on. Torque hardware to 47
C. Proceed with stacking of remaining modules, checking that stack is plumb in both axes as stacking progress- es before torquing hardware. Be certain to check the layout/wiring diagram for correct horizontal orientation to provide proper polarity interconnection as stacking progresses. See Figure 16 for completed assembly.
