Handling of Modules 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. Tip Over Procedure In order to stack modules in the horizontal position, refer to Figures 9 through 11 to perform the tip-over procedure. -

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). -

To insure personnel safety, and equipment protection, operation, and reliability, the battery rack should be connected to the Common Bonding Network (CBN). 2. Electrical continuity between modules is provided through the use of serrated hardware. Testing has shown that standard sys- tems are compliant with the GR-1089-CORE, Issue 4, Section 9 requirements of the Bonding and Grounding tests.
