Rack Assembly

3.Using a rated lifting device, load batteries onto TOP shelf rails in accordance with your wiring diagram. Take note of where each numbered battery should be placed, and the proper positioning of its positive and negative terminals.

Refer to step 3 on page 18 for similar procedure.

4.Make all specified TOP shelf battery-to-battery and row-to-row connections. Refer to “Wiring the batteries” on page 18.

Shelf-to-shelf wiring

Shelf-to-shelf wiring takes place after ALL of the shelves in your rack have been fully assembled and their batteries wired together in numerical sequence. Start with the top shelf and work down.

Review “Safety” on page 1 for safety warnings and caution notices. Take heed of all safety information before proceeding with battery connections. Failure to

Warning comply could result in serious injury or death!

Using the supplied shelf-to-shelf cable, connect the HIGHEST-numbered battery on the TOP shelf to the LOWEST-numbered battery on the SECOND shelf. Then connect the highest-numbered battery on the second shelf to the lowest-numbered battery on the third shelf. Finally, connect the highest- numbered battery on the third shelf to the lowest-numbered battery on the fourth shelf.

Prior to connecting batteries, use a voltmeter to check the voltage between those terminals being connected. Any reading other than zero is unacceptable.

Note

Follow these steps for each shelf-to-shelf connection:

1.Refer to your wiring diagrams for proper cabling and termination points.

2.Before making connections, apply two (2) cable boots.

3.Connect one cable end to the open negative (-) terminal on the last battery in the upper shelf. Snap cable boot over the connected lug/terminal.

4.Apply a “protective” boot (not supplied) to the other cable end, then snake the cable downward through (space in) centrally located rails.

Boot Your Cable!!!
