4.3 Connect to Utility
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using
extension cords and adapter plugs.(Ensure proper grounding if you are using extension
cords).
4.4 Connect the Loads
Plug the loads into the output connectors of the UPS. To use the UPS as a master on-off
switch, make sure that all of the loads are switched on.
4.5 Mains connection
UPScanbe alwaysconnectedto themains,whichwillallowUPSbatteries chargingandthis
willnot damagethe UPS.Even whenthe outputisswitchedoff,the inputto theUPS should
be ON.
4.6 Charging the Battery
The UPS charges its battery whenever it is connected to utility power. For best results,
charge the battery for 8 hours before use. It is acceptable to use the UPS without first
charging the battery, but run time may be reduced.
4.7 RJ 45 Connection
Connectthetelephone linetoRJ45connectorofUPS-INandUPS-OUT RJ 45isconnected
to the modem input. It protects from Lightning surges.
CAUTION:
1. The UPS output can be used only for electronic loads such as computers and telecom
munications equipment. Please donot connect laser printer to the power backed up
output. It can be connected to the surge protected socket. A laser printer periodically
draws significantly more power than when idle, and will overload the UPS
2. Please ensure more than 5% of the rated total load is connected.
4. Installation
4.1 Inspection
Inspect the UPS upon receipt. Notify the carrier and dealer if there is damage. The
packaging is recyclable; save it for re-use or dispose of it properly.
4.2 Placement
Install the UPS in a protected area with adequate air flow and free of excessive dust.
Do not operate the UPS if the temperature and humidity are not within the specified limits.
In colder territories allow the UPS to come to room temperature before operating.

User Manual Power UPS 500 Page 11
5. Operation
5.1 To reset the UPS microprocessor, in case of an unknown situation:
With the UPS unplugged from the wall outlet, press the OFF button for 2 sec. This will
reset the internal microprocessor.
5.2 Turn off UPS Output Power
To turn off the UPS’s output power, press the OFF button longer than 2 sec.
5.3 Turn on UPS Output Power
Press the ON button 2 sec to switch the UPS on and to supply power to the loads.
NOTE: The UPS is always on (CPU is operating) whenever it is plugged in and mains is
present. Even when the UPS is off it maintains the battery and will respond to commands
received through the computer interface port.
5.4 UPS Self-test
Use the self-test to verify both the operation of the UPS and the condition of the battery.
With the UPS plugged in to normal mains voltage, activate the self-test by pressing the
ON button.
5.5 Auto Voltage Regulation
The UPS automatically corrects high and low utility voltages so that the loads receive
voltage within the normal range.
5.6 DC (Cold) Start
When the UPS is off and there is no utility power, use the cold start feature to apply power
to the loads from the UPS‘s battery. Press the ON button until the red BAT-Led illumi-
nates. Release the button when the loads are powered within 4 seconds.
5.7 Shutdown Mode on 500VA model
In the shutdown mode the UPS stops supplying power to the load, waiting for the return of
mains voltage. If there is no mains voltage present, external devices (e.g. servers) con-
nected to the computer interface can command the UPS to shut down. This is normally
done to preserve battery capacity after the controlled shutdown of protected servers. The
UPS will flash the front panel BAT LED in shutdown mode.

User Manual Power UPS 500 Page 12
6. Alarms
6.1 On Battery
During on-battery operation, the on-BAT Led comes on and the UPS gives an audible
alarm consisting of one beep every 4 seconds. The alarm stops when the UPS returns to
on-line operation.
Press the ON button during on-battery operation to stop the beeping. This mutes the
current alarm only, the next on-battery alarm will be audible. Shutting off the audible
alarm in this way does not affect the computer interface alarm.
6.2 Overload
When the UPS is overloaded (when the connected loads exceed maximum load) the UPS
gives a continuous audible alarm (beep). The alarm remains on until the overload is
removed. Disconnect nonessential load equipment from the UPS to eliminate the over-
load.
6.3 Weak Battery
The UPS beeps for 1x30 Sec. and the BAT Led flashes every 30 seconds, if the battery
fails the self-test. The UPS repeats the alarm every 30 sec. Perform the self-test proce-
dure again to confirm the replace battery condition. The alarm stops when the battery
passes the self-test.

10 About the Battery
1. Life of the battery depends on operating temperature and on the number of discharge
cycles.
2.“WHEN DOESTHE BATTERYNEEDREPLACING?”
Ifthe BATLedonthefront oftheUPS flashes1x30secandbuzzersounds, itimpliesthat the
batterywill nolonger holda fullcharge. Underthiscircumstances,ifa powerfailure occurs,
the UPS runs less than half its normal length of time when compared to a good battery.
Perform the following steps to make sure the battery needs replacing:
1) make sure the UPS is plugged into a live wall outlet
2) charge the UPS for at least 8 hours
3) turn the UPS off and then back on
4) press ON switch to force a self-test
After step 4, if the BAT Led still flashes, there might be something wrong with the battery.
Since the battery will eventually wear out and needs to be replaced, please contact your
local dealer and ask for the battery replacement services
3. Extendability of battery is not possible in this UPS. Please do not add external battery to
the UPS. This will void the Warranty.

User Manual Power UPS 500 Page 18
12 Storage
Store the UPS covered and placed upright in a cool place, with its battery fully charged.
Before storing charge the batteries for at least 24 hours. Disconnect any cables con-
nected to the computer interface port to avoid unnecessarily draining the battery.
Make sure that the UPS is switched off.
Storing the unit for longer than 3 months can reduce the life of the batteries. To
maintain the normal life expectancy, recharge the battery. For chargeing the battery refer
section 4.7.

SafeWare Program:
Each time the Windows 95 program is started , SafeWare for windows 95 will
automatically start and run unless the user deletes the SafeWare Icon from the Windows
95 Startup folder. By default, SafeWare will start in “Minimized” mode.
Once the SafeWare application has been closed, clicking on the SafeWare icon in
either the SafeWare folder or the Startup folder will once again start SafeWare.
Main SafeWare Screen
The safeWare screen makes a variety of AI-UPS status and control information available
to the user. The left portion of the SafeWare screen displays six large gauges that are
labeled:
Input Voltage Output voltage
Input Frequency Output Frequency
Battery Level Load Level.
These gauges are similar in appearance to automative gauges and graphically indicate
the current values of the specific labeled AI-UPS categories. A text box below each
gauge also shows the exact value or percentage of the specific category.
The top right hand portion of the SafeWare screen has indicators for the input power and
AI-UPS status. The indicators will turn on, off or flash to indicate the current input Power
andAI-UPS condition.they include:
Power Normal Battery Low UPS Fault
Power Failure Battery Weak UPS Overload
Just below the Power and AI-UPS Status indicators is the Countdown Time display box.
This box will indicate the countdown time that has been entered by the user in the
SafeWare Settings. In case of a loss of utility power, the value in the box will decrease
until it reaches zero at which time SafeWare will cause the Windows 95 save/exit routine
to begin. At any time during the countdown, the user may click on the box to the left of
the Abort Countdown box at which time the countdown will resume, or 2) the AI-UPS
reaches a battery low condition. If a battery low condition occurs, SafeWare will override
the abort command and automatically run the Windows 95 safe/exit routine and cause
the computer system and AI-UPS to shutdown.
The lower right hand portion of the SafeWare screen displays the Waveform chart which
is a graphical waveform representation of the AI-UPS operational parameters. there are
three AI-UPS categories that can be displayed on the Waveform chart:Input/Output
Voltage Waveform, Input/Output Frequency Waveform, and Battery/Load Level Wave-
form. By clicking on the Toggle Waveform button user can display the different wave-
forms.
The Waveform chart displays information in a time based format. Time markings below
the chart will inform the user of the time that a power event occurred. Buttons to the right
