SYSTEM OVERVIEW
This UPS protects computers, internetworking, security, and telecommunications equip-
ment from blackouts, brownouts, overvoltages, and surges. During normal AC operation,
the UPS will quietly and confidently protect your system from power anomalies.
The UPS will charge the batteries with the UPS in the on or off position when the UPS is
plugged into the wall outlet and there is an acceptable AC voltage present (100 - 140VAC).
When a blackout, brownout, or an overvoltage condition occurs; the UPS will transfer to the
battery mode, the On Battery indicator will illuminate and the audible alarm will sound once
every five seconds indicating that the commercial power is lost or unacceptable. When the
commercial power returns or is at an acceptable level, the UPS will automatically transfer
back to the AC normal mode and start recharging the batteries. During an extended outage
when there is approximately two minutes of backup time remaining the audible alarm will
sound twice every five seconds. This Low Battery Warning is letting the user know that they
should save all open files and turn off their computer. When the batteries reach the
predetermined level the UPS will automatically shutdown protecting the batteries from
over discharging. Once the utility power returns the UPS will automatically restart, provid-
ing safe usable power to the connected equipment and start recharging the batteries.
ON / OFF BUTTON
Press and hold the On/Off Button for one beep then release, to turn the UPS on and supply
power to the load. The load is immediately powered while the UPS runs a five second self
test. Press the On/Off Button for at least one second then release, to turn the UPS off. The
UPS will continue to charge the batteries whenever it is plugged into a wall outlet and there
is an acceptable AC voltage present.
USB COMMUNICATIONS PORT
The USB Protocol is HID. The USB port operates with the standard Windows USB drivers
and does not require any additional USB drivers. Simply plug the USB cable into the UPS
and the computer then follow the prompts on the screen.
WEAK/BAD BATTERY
The UPS automatically tests the battery’s condition. If the battery is weak, bad or discon-
nected, the Battery capacity bar graph will flash off and on and the alarm will beep three
times every thirty seconds until the battery is reconnected or replaced. It is recommended
that the UPS be allowed to charge overnight before performing a battery test to confirm a
Weak/Bad Battery condition. This alarm will be repeated until the batteries pass a self test.
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the Load capacity
bar graph will flash off and on and the alarm will sound 1 beep every half second. This
alarm will remain on until the excess load is removed or the UPS’s self protection circuit
shuts the UPS down.
POWER MONITORING SOFTWARE
The UPS comes with power monitoring software. See the software CD for the installation
of the power monitoring software.
ALARMS
ON BATTERY
When the UPS is operating on the batteries, the On Battery icon will illuminate and the
audible alarm will sound once every five seconds. The alarm will stop once the UPS
returns to the AC normal mode.
LOW BATTERY WARNING
The UPS will sound two beeps every five seconds when the battery reserve runs low. This
condition will continue until AC returns or the UPS shuts down from battery exhaustion.
UPS FAULT
When the UPS detects a hardware fault, the Fault icon will illuminate, the alarm will sound
continuously and the output will turn off. The fault condition, in some instances, may be
reset by turning the UPS off and then on again.
