External Battery Connection
(Select Models)
Your UPS comes with a robust internal
battery system; external batteries are
needed only to extend runtime. Adding
external batteries will increase recharge time
as well as runtime. This UPS supports
BP24V15RT2U (limit 1), BP24V28-2U (limit
1) and BP24V70-3U (multi-pack).
The illustration (see
3
) shows the location of your UPS’s External Battery Connector
A
where
you will insert the battery pack cable. Complete installation instructions for your battery pack
appear in the battery pack owner’s manual. Make sure that cables are fully inserted into their
connectors. Small sparks may result during battery connection; this is normal.
Do not connect or disconnect battery packs when the UPS is running on battery power.
CAUTION! When an external battery pack is connected, make sure the AC load does not
exceed the nameplate rating. Select models are derated when an external battery pack
is connected. See UPS nameplate label for derating details.

Note:
1. The runtime will automatically recalculate once the External Battery Pack Tool process is complete.
2. If the setup will no longer include external batteries, the UPS can be configured to work without external
batteries via the LCD Screen. See External Battery Settings Control section under Basic Operation for details.
3. If external battery packs are removed, the UPS must be reset to “NO EXTERNAL BATTERY” via the LCD
interface or the External Battery Configuration Program available on the Tripp Lite website. Failure to do so
may result in damage to the internal batteries due to over-charging.
