Optional Connection
Additional Battery Pack Connection
3
The UPS system includes one external battery pack. Additional external battery packs are
not required to operate the UPS system, but they will provide additional battery backup
runtime for connected equipment.
Connect multiple battery packs by daisy-chaining the second to the first, daisy-chaining
the third to the second and so on. Note: When daisy-chaining multiple battery packs, they
should be identical models of similar age and level of wear. Make sure that cables are
inserted fully into connectors. Small sparks may occur during battery connection; this is
normal. Do not connect or disconnect battery packs when the UPS is operating from
battery power. Multiple battery packs provide longer runtimes, but also require longer
recharge times.
Additional Battery Pack Connection Procedure
3a (1) Remove the retention bracket from one of the first battery pack's rear panel
connectors. (The other connector will already be attached to the power module or another
battery pack.) (2) Insert one end of the detachable power cable into each battery pack,
making sure to insert the cable connectors into the battery pack connectors fully. (3)
Attach the retention brackets to the right of each connector, using the screw holes set to
the right of the original bracket position. Warning: Always use the connector retention
brackets to secure the battery pack connections. Do not attempt to operate the UPS
system without the connector retention brackets in place.
3b
If two or more external battery packs (including the external battery pack that is included
with the UPS system) are connected to the UPS system, move the Battery Charge Level
Switch from the default position (labeled "NORMAL") to the right-hand position
(labeled "HIGH"). Warning: Setting the Battery Charge Level Switch to "HIGH" with
only one external battery pack connected to the UPS system may damage the external
battery pack.
