Adding or Replacing Internal Batteries
(continued)
DANGER!
BATTERY CARTRIDGE FUSES MUST BE INSERTED LAST DUE TO THE DANGER OF POTENTIAL
ARCING OF CONNECTORS.
FUSE REPLA
CEMENT
The fuses protect against short circuit damage. If a heavy overload or short circuit is encountered,
a fuse will blow. A battery pack with a blown fuse will not deliver any output voltage to the UPS
system.
DANGER!
The fuses must be replaced by a qualified electrician. To reduce the risk of fire, replace only with
fuses of the same type or rating (UL-recognized 30A 600VDC rated cartridge fuses or equivalent).
Use a voltmeter (user-supplied) to test the voltage of the battery pack.
Observe proper polarity: connect the voltmeter's BLACK probe to the
battery pack's BLACK connector; connect the voltmeter's RED probe
to the battery pack's RED connector. To get a proper reading, make
sure the voltmeter's probes touch the metal contacts inside the battery
pack's connectors. The battery pack's Acceptable DC Voltage Range
is between 220 and 280V DC. If several attempts at voltmeter tests
yield results outside this range, contact Tripp Lite for assistance in
determining the possible causes of the incorrect voltage reading.

Connect the BLUE and WHITE jumper cables on each internal
battery pack to its corresponding fuse block. See printing next to fuse

Insert the battery cartridge fuses into each fuse block. The fuses are
identical, and can be inserted into any of the blocks. Make sure that
the fuses are firmly snapped into place.
