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).
