7.2 Dummy Cells within a Module
Where application voltage requires, a dummy cell can replace
a live cell in a module. For example, a 46 volt, three-cell per
module system may consist of seven full modules and one
module containing two live cells and either an empty space,
or a dummy cell.

8.0 System Assembly
8.1 Horizontal Single Stack
Consult layout/wiring diagram for total number and type of
module assemblies in system. There can be varying combi-
nations of cell arrangements within the module. May contain
dummy cells depending on total system voltage.
Compare required module assemblies called for on layout/
wiring diagram with modules in shipment for completeness
before continuing further.
8.1.1 Bottom I-beam Supports
Locate bottom I-beam supports and M10 I-beam hardware
kit. I-beam supports and seismic shims should be attached to
the appropriate module assembly shown on the layout/wiring
diagram prior to removal from shipping pallet.
NOTE: Seismic shims will be supplied with systems for which
they are required to maintain seismic compliance.
Secure I-beam support to a module channel as shown in supplied
drawing, with access slots outward. Please refer to Figure 8 and 9
for general hardware installation information. Seismic shims, when
supplied, are placed between the channel and the nut and oriented
so as to not extend beyond the end of the channel. Torque hard-
ware to 47 Newton-meters (35 ft-lbs) using insulated tools. When
correctly attached, the I-beam support will be flush with the front
module channel and approximately 13mm (0.50”) away from the
back of the module. The side of the I-beam support will be approxi-
mately 10mm (0.38”) away from the end of the channels.
NOTE: The use of leveling shims is required when assembling
any Absolyte system in order to meet seismic requirements.
Failure to use the shims to level each module and to fill spac-
es between tray channels during module assembly will result
in the assembly not meeting seismic certification criteria.
Similarly, install the remaining I-beam support on the other
side of the module (see Figure 10).
