Installing other battery systems
1 Unpack the battery box and place it according to the equipment
layout plan.

If the batteries do not have the same dates, contact your supplier.
The battery cells can deliver high currents when short-circuited. Make
sure that you do not inadvertently short-circuit the terminals of the
batteries.
5 Place the batteries in the battery box.
6 Locate the black wires supplied with the box.
7 Connect the battery packs in series by installing the black wires
between the + (large) terminal of one battery pack to the - (small)
terminal of the next battery pack.
8 Connect the black wire inside the battery box to the remaining
positive (+) terminal and the red wire to the remaining negative (-)
terminal.

mm (36 in.) of the cabinet it is serving. See Figure 87 on page 211.
