When the unit is plugged in directly to a wall outlet, it makes
a continuous beeping sound. I removed all devices that were
plugged into the ups. I plugged an electric pencil sharpener
into the Surge Protection outlets, and it will still work, even
though the ups is beeping.
When I plug the sharpener into the Battery Backup + Surge
Protection outlets, the sharpener does not work. The circuit
breaker button remains out at all times. I pressed and held
it for a few seconds, but it pops right out when released.
I also disconnected the battery that was connected to a
red & black wire. I re-connected the black cable, and touched
the red cable to the lead on the battery, and it sparked. The
black cable has a white plastic casing around the lead which
prevents it from being connected to the battery incorrectly.
Can this ups be fixed?
Thanks a bunch,
