a) Align the cell side restraint plate against the cell while keeping the plate straight and
parallel to the module side wall. Adjust bolts so they are both protruding approximately the
same amount out from the side of the module.
b) Turn each bolt one rotation at a time alternating between the two bolts, ensuring to keep
the cell side restraint plate straight and parallel to the module’s walls and the protruding
bolt length of the two bolts the same.
c) Monitor the bolt/washer/nut assemblies to ensure that the flange nut remains nested in the
module side panel recess and the bolt perpendicular to the cell side restraint plate.
d) Continue to tighten the bolts until the GAP between the outside of the cell side restraint
plate and the inside of the module is within the target range as listed in Table 2 in
Appendix C
e) If there is no measuring device available the bolts should be tightened until the inter-cell
connectors can be properly installed. Vertical connectors – connecting posts on cells on
tiers directly above/below each other – will be straight, plumb and parallel to all other
vertical connectors. See Figure 9-1.
11. The front cell restraint bar hardware should be completely tightened at this time. To maintain
seismic ratings, all front cell restraint bar hardware must be installed and torqued to 6 Ft-Lb (8 N-
m). See Figure 6-4
NOTE: Additional Module Assembly Guidelines
• Follow the spacing guidelines detailed in Table 2 in Appendix C and noted
above
• It is not a requirement that the cell covers touch
• It is not a requirement that the cell cover spacing is exactly the same
• It is not a requirement that the side restraint plate bolts bottom out
• Torque not to exceed 15 Ft-Lbs for the side restraint bolt/washer/nut
assemblies
For systems using cam assemblies in place of side restraint plate bolts, refer to
Appendix B
