Optional Installation
External Battery Connection
3
(Select Models)
Your UPS contains a robust internal battery
system. External batteries are needed only
to extend runtime. Use only Tripp Lite
external battery packs with overcurrent
protection. Adding external batteries will
increase recharge time, as well as runtime.
Installation is by qualified Service personnel
only. See the battery pack owner's manual
for complete installation instructions. Make sure 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. Your UPS supports the
following battery packs available from Tripp Lite. Contact Tripp Lite Customer Support at
773.869.1234 for the appropriate Tripp Lite battery pack to connect.
48V Battery Packs
• BP48V24-2U, 18Ah, (limit 1)
• BP48V27-2US, 27Ah (unlimited)
• BP48V60RT-3U, 42Ah (unlimited)
When installing your UPS with external batteries, be sure to connect the ground strap between
the external battery packs to the metal enclosure of the UPS before connecting to the two-
conductor external battery pack cables. Follow installation directions in accordance with the
external battery pack owner's manual using the ground strap included with the external battery
packs.
The illustration (see
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.
When connecting external batteries to the UPS, go to the Tripp Lite website at
tripplite.com/en/support/bpconfig/index.cfm to download the External Battery Pack Utility
software to configure your UPS for external battery support.
Notes:
1. The runtime and charger rate 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 panel. 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.
