Note
•
When connecting backup batteries, make sure to use the same number of Back-up Battery Cables as
the number of installed shelves, even between connected batteries. For example, if 4 shelves are
installed, 4 cables must be attached to each terminal of each battery, as shown above.
•
If the length of time that power must be maintained after a power failure exceeds the capacity of the
backup batteries, connect additional sets of 3 backup batteries as required.
