8.2.1	Stacking Base Modules

It is recommended that all of the first modules with bottom supports attached (see Section 8.1.1) be placed in position first. A chalk line floor mark should be used to assure all stacks will be in a straight line. This applies for stacks end- to-end or end-to-end and back-to-back. Refer to Sections 6.5 and 8.1.3 for handling and tip over procedures.

For stacks end-to-end, module ends should be butted together so that module side channel ends meet (see Figure 17).

POSITIONING HORIZONTAL BASE MODULES

Figure 17

For stacks back-to-back, the two base modules are posi- tioned to provide a minimum 4.5” spacing between the bottoms of the modules (not I-beam edges). Refer back to Figure 1.

Refer to layout/wiring diagram for seismic shim require- ments.

8.2.2 Stack Tie Plates

At this time stack tie plates should be installed. It will be necessary to temporarily remove the hardware fastening the base modules to the I-beams.

To achieve maximum stack stability, especially where seismic conditions may exist, as well as proper interfacing of inter-stack connections, metal tie plates are provided. The plates used on stacks end to end are 3” x 1” x 1/8” with two 9/16” holes. Use one tie plate at each interface to connect the module channels of adjacent stacks. See Figure 18.

Position plates on the module channels and secure with hardware as shown. Where stacks have different heights (for example a 3 high stack adjacent to 4 high stack), install plates on shorter stack top module and adjacent module. Torque hardware to 47 Newton-meters (35 Ft-Lbs).

8.2.3 Horizontal Stacking

When all base modules are set in place, continue with stacking of subsequent modules. Procedures for assem- bly of multiple horizontal stacks are the same as outlined in section 8.1.3. Also consult layout/wiring diagram. Each stack should be built up in sequence to the same level until the top modules in all stacks are the last to be installed. The use of a line chord attached to upper mod- ule corners of opposite end modules as stacking pro- gresses aids in alignment.

This completes the mechanical assembly of the battery system.

For installation of intermodular connections and terminal plate assembly, see Section 9.

For installation of protective module cover, see Section 11.

9.0 Post Preparation

All cell posts were greased at the factory. Using either a brass bristle suede shoe brush or 3M Scotch Brite scour- ing pad, brighten the flat copper terminal surfaces to
