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
