of two battery packs in each group. A maximum of four groups
with eight battery packs can be connected in parallel. If more
than two battery packs need to be connected to the 15 kVA/20
kVA UPS with long backup time, the battery packs should be
connected in parallel and then connected to the battery input
ports of the UPS, as shown in the following figure. Connect
battery packs 1 and 2 in series, battery packs 3 and 4 in series,
battery packs 5 and 6 in series, and battery packs 7 and 8 in
series. Connect battery packs 1, 3, 5, and 7 in parallel and battery
packs 2, 4, 6, and 8 in parallel.

battery packs of the same model and specifications can be
installed or replaced. Do not use battery packs of different models
or specifications together. For details, see the battery pack
nameplate.
