Optional Installation
External Battery Connection (Select Models)
3
Your UPS comes with 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.
24V Battery Packs
• BP24V15RT2U (limit 1)
• BP24V28-2U (limit 1)
• BP24V70-3U (multi-pack)
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.

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.

Notes:
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.
