Adding or Replacing Internal Batteries (continued)

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

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.

DANGER!

BATTERY CARTRIDGE FUSES MUST BE INSERTED LAST DUE TO THE DANGER OF POTENTIAL ARCING OF CONNECTORS.

FUSE REPLACEMENT

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).

12Use 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.
