Tripp Lite External Battery Packs have output voltages of either 36 volts (BP36V14-2U), 48 volts
(BP48V24-2U) or 72 volts (BP72V12-2U) and are designed for use with various Tripp Lite UPS systems
equipped with external battery pack connectors. When used with the appropriate Tripp Lite UPS, they meet
UL standard 1778. The BP48V24-2U may also be suitable for use with 48V DC input telecommunications
equipment.

SAFETY
• Use caution when lifting Battery Packs. Because of the considerable weight of all Rackmount
Battery Packs, at least two people should assist in lifting and installing them.
• 36V and 72V Battery Packs and UPS systems use identical power cables and plugs; make
certain that your Battery Packs and UPS use the same DC voltage before connecting them.
• Suggested mounting procedures are for common rack types and may not be appropriate for all rack
configurations. User must determine the fitness of rack- and wallmount hardware and procedures
before mounting.
• When connecting multiple Battery Packs to a single UPS, the Battery Packs should be approximately
the same age.
• It is normal for sparks to occur inside external battery connectors during final battery connection.
• Do not unplug external batteries from the UPS while the UPS is operating on battery power, due to
the possibility of dangerous arcing.
• There are no user-serviceable parts inside the Battery Packs. Do not open the Battery Packs for
any reason.
• Battery Replacement must be performed by factory authorized service personnel. Because batteries
present a risk of electrical shock and burn from high short-circuit current, observe proper precautions.
Unplug the Battery Pack from the UPS before performing battery replacement. Do not short or bridge
battery terminals with any object. Use tools with insulated handles. Remove metal objects such as
watches and rings before working with batteries. Do not open batteries. Replace batteries only with
sealed lead-acid batteries of the same number, type, voltage and amp hour capacity.
• Do not dispose of batteries in a fire. The batteries are recyclable. Proper disposal of batteries is required;
refer to your local codes for disposal requirements. In the USA only, you may call 1-800-SAV-LEAD
(1-800-728-5323) for complete recycling information.
The BP4824-2U can be configured to match black or grey equipment. To match grey equipment, mount
the grey mounting ears in front. To match black equipment, switch the grey front panel on the unit for the
black front panel included, and mount the black mounting ears in front. (See mounting instructions for exact
mounting ear placement.)
SUGGESTED RACKMOUNT INSTALLATION
FOR 4-POST ENCLOSURES
1) Measure the depth of your rack from the outside surface of the front mounting rail to the outside surface
of the rear mounting rail.
2) On both sides of your Battery Pack, connect
both front mounting ears (A) with four screws
and flat washers each (B) so their mounting
surfaces are even with the front of your Battery
Pack's metal case. Connect the mounting extensions (C) to the Battery Pack using four
screws and flat washers (D) each. Connect the
rear mounting ears (E) to the mounting extension using four wing bolts and flat washers (F)
and locking nuts (G) each—the wing bolts
should be left only finger-tight so that they may
be adjusted later. Adjust the mounting extensions and rear mounting ears so that the distance from the front mounting ears to rear
mounting ears matches the depth of your rack.
3)Have one or more assistants lift the Battery
Pack and hold it in position until this step is
complete. Insert the Battery Pack into its intended rack space, pressing its rear mounting
ears (H) inward so that they fit past the rack's
front (J) and rear (K) mounting rails, until the
mounting surfaces of the front ears (L) meet the
outside of the rack's front rails. Adjust the rear
mounting ear until the mounting surface of the rear ears meet the outside of the rear rails, then tighten
the wing bolts holding the mounting ears to the mounting extensions. Connect the front mounting
ears of the Battery Pack to the rack's front mounting rails with two screws and flat washers (M, user
supplied: match to the rails' threads) on each side. Connect the rear mounting ears to the rear mounting
rails of the rack with two screws and flat washers (N, user supplied: match to the rails' threads) on
each side.
1) On both sides of your Battery Pack, connect
one mounting ear (A) with four screws and flat
washers (B) to the Battery Pack's middle four
mounting holes. The mounting surface of the
ear should face the front of the Battery Pack.
2)Have one or more assistants lift the Battery
Pack and hold it in position until this step is
complete. Insert the Battery Pack into its
intended rack space, until the mounting surfaces of its ears (C) meet the outside of the
rack's rails (D). Connect the mounting ears to
the rails with two screws and flat washers
(user supplied, E) on each side.
SUGGESTED WALLMOUNT
INSTALLATION
1) On both sides of your Battery Pack, connect
one mounting ear (A) to the Battery Pack's
four front mounting holes and
another mounting ear (B) to the four rear
mounting holes, using four screws and flat
washers (C) with each ear. The mounting
surfaces of the ears should face up and out,
and the bottom of the ears should be flush
with the bottom of the Battery Pack.
2)Have one or more assistants lift the Battery
Pack and hold it in position until this step is
complete. Move the Battery Pack to its intended wall space
and hold it so that the mounting surfaces of its ears (D) are
pressed to the wall. Attach the ears to the wall with two
screws and flat washers (user supplied, E) each.
1) On one side of your battery pack, connect one mounting
ear (A) to the Battery Pack's four front mounting holes and
another mounting ear (B) to the four rear mounting holes,
using four screws and flat washers (C) with each ear. The
ends of the mounting ears should stick out on opposite
sides of the Battery Pack.
2)Have one or more assistants lift the Battery Pack and hold
it in position until this step is complete. Move the Battery
Pack to its intended floor space and hold it so that the
mounting surfaces of its ears (D) are level with the floor.
Bolt the ears to the floor with two screws and flat washers
(user supplied, E) each. Without bolting the Battery Pack
in position, there is a danger of tipping.
Your Battery Pack may be positioned safely in an upright position
without mounting screws with the addition of Stabilizer Feet (part
#300842), sold separately from Tripp Lite.
BATTERY PACK CONNECTION
BP48V24-2U Battery Packs have a blue 175-amp polarized plug
(A) on an output cord permanently connected to the rear panel.
Simply plug the output cord directly into the external battery
connector of your UPS. (See your UPS manual for external battery
connector description and location.) Note that only
one of these Battery Packs is generally connected
to a UPS at one time. For longer runtime, you may
connect two to a single UPS using a 48V YAdapter Cable sold separately by Tripp Lite, or use
one or more BP48V60-3U Tripp Lite Battery
Packs with daisy-chain capability.
BP36V14-2U or BP72V12-2U Battery Packs
feature dual input/output receptacles on their rear
panels (B) . To connect to a UPS, insert one end of
the detachable power cable (C) into either plug on
the rear of the Battery Pack and the cable's other end
into the external battery connector of your UPS.
(See your UPS manual for external battery connector description and location.) To connect multiple
Battery Packs to a single UPS for greatly increased
runtime, connect the output of the first Battery Pack
to the UPS's external battery connector, then "daisy
chain" the others: connect an input/output plug on
the second Battery Pack to an input/output plug on
the first, a plug on third to a plug on the second and
so on. Note that multiple Battery Pack arrays will
provide longer runtimes, but will also require
longer recharge times.
There is a fuse array inside the Battery Packs. If a heavy overload or short circuit is encountered, a fuse
will open (blow). A Battery Pack with a blown fuse will deliver no output voltage at any load. A qualified
technician must replace the fuses. Contact Tripp Lite Customer Support for additional information.
MAINTENANCE
Rackmount Battery Packs require no maintenance but should be kept dry at all times. Avoid installation
in locations with high heat and/or humidity. The Battery Packs should be kept fully charged by being
connected to an active UPS system, not left in a depleted condition. Batteries left in a discharged state will
suffer a permanent loss of capacity.
INTERNAL BATTERY REPLACEMENT
The batteries in the Battery Packs will eventually wear out and be unable to provide adequate backup times.
The batteries should only be replaced by factory authorized service personnel. Tripp Lite offers an exchange
program for North American customers wherein they may exchange worn-out Battery Packs for new ones
at a price comparable to the cost of individual battery replacement. For more details, call Tripp Lite at
(773) 869-1234.
STORAGE
Disconnect your Battery Pack's power cable before storing. If you plan to store your Battery Pack for an
extended period of time, fully recharge its batteries every three months by connecting it to a UPS that is
connected to AC input for 4-6 hours.
SERVICE
If returning your Battery Pack to Tripp Lite for service, please pack it carefully in its ORIGINAL PACKING
MATERIAL that came with the unit. Enclose a letter describing the symptoms of your problem. If the UPS
is within the 2-year warranty period, enclose a copy of your sales receipt.
