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.
