5.
Arrange the batteries in the cabinet or rack. If optional straps are
included, install the straps as shown in the battery installation
diagram that came with the batteries.
Arrange the batteries so there is as much air flow as possible
around the batteries and so the batteries can be cooled as much as
possible.
Some external battery cabinets have cooling slots cut in the shelves
to increase air flow. Arrange the batteries so these slots are not
blocked. Some larger batteries must sit with the longest battery
dimension in the same direction as the longest shelf dimension.
These batteries will partly block the cooling slots. However, if you
place the batteries next to the outside edge of the shelf to leave as
much space between the batteries as possible, there will be plenty
of air flow for cooling.

Never install the batteries in an air-tight enclosure.
6.
All FE and QFE models with external batteries use a fuse in the
external battery cabinet. The external battery cabinet fuse protects
the battery cables. The battery installation diagram shows the fuse
type and position. A system DC fuse is inside the UPS.
Connect the DC fuse(s) as shown in the battery installation diagram.
(The fuse may be on the terminal strip.)
7.
Find the battery cable assembly that connects to the UPS. (If you
have a removable DC plug at the UPS end, note that this end of the
cables does not go through the conduit or connect to it.)
Do not connect the external battery cables to the UPS at this time,
but pull them through the conduit from the UPS to the cabinet or
rack. Do not connect the cables to the batteries or cabinet terminals
yet.
If you have more than one external battery cabinet, find the battery
cable assembly that will connect the external battery cabinets. Pull
the cables through the conduit that you installed between the
cabinets.
