1. If not already done, remove cell front restraint bars and cell side restraint plates. Refer to Section
6.5.3 for detailed instructions on removal.
2. Prior to cell insertion assemble the two (2) side restraint plate bolts and washers (when required)
into the floating flanged nuts through the hex-shaped recessed holes on the right side of the
modules (or both sides for the 45”, 49” and 58” wide modules); Ref Figure 6-4A, Flange Nut
Detail). Do not completely tighten the bolt/washer/nut assemblies at this time.
3. Transfer cells to be installed onto lift table. Do not exceed maximum weight limit of lifting
equipment or lift table. In many cases, cells will need to be moved one at a time.
4. Position lift table in front of empty modules, starting with the lowest empty module. The top of the
lift table should be even with the bottom surface of the module. Cell terminals should face away
from the module opening. Any metal surfaces that may come into contact with the terminals
should be insulated.
5. After checking the cell polarity/orientation against the system drawing/connection diagram, slide
cell from the lift table into the empty module. Cell should slide directly into the module and should
not drop or need to be lifted into place. To prevent damage to the cells, do not attempt to install
cells into a module that is above or below the surface of the lift table. Slide the cell to the left wall
of the module (or to the center partition of the 45”, 49” and 58” wide modules).
6. When the cell is fully inserted into the module, the jar/cover seal will protrude slightly beyond the
front lip of the module.
7. Install the remaining cells within the module repeating steps 2-5 until the module is full. After
each new cell is installed, insert metal cell spacer plate between each cell. The spacer plate
should be pushed to the back of the module. Slide the cell over to the previously installed cell.
This will ensure that the cells are all biased toward the side opposite of the cell side restraint
plate and side restraint hardware. This will allow adequate room for ease of insertion of the cell
side restraint plate. When installed properly, cell spacer plates should not reach the jar/cover
joint. If the cell spacer plate extends beyond the lower lip of the module, remove it, check for any
obstructions and re-install. See Figure 6-4
8. Once all cells are installed within the module and spacer plates are in place, insert the cell side
restraint plate as shown in Figure 6-4. The cell side restraint plate should also be pushed to the
back of the module. When properly installed, the cell side restraint plate should be fully seated
against the back of the module and the front edge of the plate should not reach the jar cover seal.
With all cells, spacer plates, and cell side restraint plates installed within the module, the front cell
restraint bar should be installed using all supplied hardware. The front restraint bar hardware
should not be completely tightened at this time. See Figure 6-4
9. Starting with the top module, side restraint plate bolts (installed earlier as described in step 2)
should now be tightened. Bolts should be hand-tightened first to ensure they are square against
the module and the cell side restraint plate. See Figure 6-4
10. The following steps are to be followed for the completion of the assembly of the side restraint
plate bolts:
NOTE: Handling of Individual Cells
• When removed, do not allow cells to drop. Cells must be laid down in a controlled
manner. A battery dropped may be damaged by the impact of falling even short
distances. Some damage may occur to internal components, not visible at installation.
• Batteries should not be laid, slid or dragged across pallets or rough floors. Nails,
pebbles, floor imperfections and other obstructions can damage jar, cover or weld.
• If the lift table is not at proper elevation and cells are pushed in at an angle, the jar to
cover seal may be compromised by the module’s steel edge.
