a module may have only one cell in a two-cell tray. For example, a 46 volt system will consist of eleven full mod- ules and one single-cell module. Assemblies can be rotat- ed 180° for proper polarity location.

8.1.1 Bottom Supports (I-beams)

Locate bottom I-beam supports and M10 serrated flange bolts and nuts. I-beam supports and seismic shims should be attached to the appropriate module assembly shown on the layout/wiring diagram prior to removal from ship- ping pallet. Consult layout/wiring diagram for proper loca- tion of positive/negative terminals relative to I-beam.

NOTE: Failure to use seismic shims (on systems where seismic shims are indicated) will result in the assembly not meeting seismic certification crite- ria.

Secure I-beam support to a module channel as shown in Figures 7 & 8, with access slots outward. Torque hardware to 47 Newton-meters (35 Ft-Lbs) using insulated tools. The side of the I-beam will be approxi- mately 3.2mm (.125”) away from the end of the channels.

8.1.2 Handling

The module/I-beam assembly may now be removed from the pallet using methods outlined in Section 6.5. See Figures 4 and 5. Remaining modules may be removed in a similar manner.

8.1.3 Tip Over Procedure

In order to stack modules in the horizontal position, refer to Figures 9 through 11 to perform the tip-over procedure. The module/I-Beam assembly tip-over should be per- formed first. This procedure can be performed using a portable boom crane or fork lift in conjunction with the lift- ing straps and lifting shackles supplied.

A. Install lifting strap using lifting shackles in channel base holes at each end of module upper front channel as shown in Figure 9.

B. Center the lifting hook onto strap and lift until strap is under tension and raises bottom of module from floor surface.

C. While exerting manual force on the upper front of module, lower hoist until module is in horizontal posi- tion. See Figures 10 and 11.

D. After tip over procedure when module is horizontal, install the four lifting shackles and two lifting straps as shown in Figure 12 to position and handle battery in horizontal position.

TIP-OVER PROCEDUREFigure- SHACKLE9 -STRAP USAGE

NOTE (for Figure 9):

1) One strap with shackles used for tip-over procedure.

2) Observe channel hole used as well as direction of shackle insertion.

3) Tip over procedure for single modules only.
