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 was packed with your 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 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.
C A U T I O N
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
rack or cabinet. 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 battery cabinets.
Pull the cables through the conduit that you installed between
the cabinets.
