The buzzer alarm can be disabled by pressing the main on switch in backup mode.
Alarm silence function can not be performed when the battery voltage is lower than 22V or the UPS is in
energy saving mode.
3. Interface With Computer for UPS Status Monitoring
The communication port on the back of the UPS may be connected to a host computer. This port provides two different
methods for communicating with the computer.
Method 1(Contact closure):
The port simulates relays closing to communicate with the computer. Its major functions normally include some or all of
the following:
! To broadcast a warning when power fails.
! To close any open files before the battery reserves are exhausted.
! To turn off the UPS.
Method 2 (True RS-232):
This UPS communicates with the computer by sending out RS-232 data streams to one of the serial ports. Using this
method the user is able to monitor the following parameters:
PIN # Description
PIN 1 DTR +5~12Vdc (RTS).
PIN 2 UPS simulates a relay closing between Pin 2 and Pin 4 when input power fails.
PIN 3 N.C.
Common for Pin 2 and Pin 5. Pin 4 and Pin 7 can be short circuited.
PIN 4
UPS simulates a relay closing when the battery inside the UPS has less than 2 minutes backup
PIN 5
time left.
User sends a RS232 high level (5~12V) for 1 sec. This signal will turn off the UPS until proper
PIN 6 input power returns (It can operate only if UPS is in battery mode). This pin is also used for
RS232 receive pin (RXD).
PIN 7 Common ground for pin 6 and Pin 9.
PIN 8 N.C.
PIN 9 This pin is used for RS232 transmission pin (TXD).

Some computers are equipped with a special connector to link the UPS communication port to the computer. Contact
your dealer for details on software and all the various interface kits.
4. Service and Maintenance

4.1 Routine Maintenance

! Use dry soft cloths to clean the front panel and plastic parts.
! Do not use any detergent that contains alcoholic ingredient.
! The expected lifetime of the battery is around 3 years. Improper operation or harsh environment will reduce the
actual lifetime.
! Unplug the UPS from power inlet if the UPS will not operate for a long period of time.
! Charge the battery every 3 months to recover the self-discharge capacity when the UPS is in extended storage.
! When replacing batteries, use the sealed lead-acid maintenance free battery with the same number and capacity.
! Proper disposal of batteries if required. Refer to your local codes for disposal requirements.

4.2 Storage Instructions

The UPS should be stored in a cool dry location. Make sure the battery is fully charged before the UPS is stored. For
extended storage in moderate climates, the battery should be charged for 12 hours every 3 months by plugging the
power cord into the wall receptacle and turning on the main switch. Repeat every 2 months in high temperature
locations.
5. Troubleshooting
The TROUBLESHOOTING TABLE in the next page covers most of the difficulties that you may encounter under
normal working conditions. If the UPS fails to operate properly, please review the following steps before calling the
repair center:
1. Is the UPS plugged into a proper working outlet ?
2. Is the line voltage within the rating specified ?
3. Does the fuse on the rear panel need to be replaced ?
! Please do not open the metal cover.
! There are no user serviceable parts inside
! The batteries contained in this UPS are recyclable.
! The batteries contain lead and pose a hazard to the environment and human
! health if not disposed of properly.
! Do not open or mutilate the batteries. They contain an electrolyte which is toxic and harmful to the skin
and eyes.
! A battery can present a risk of electrical shock and high short circuit current. When replacing batteries,
wrist watches and jewelry such as rings should removed. Use tools with insulated handles.
! Please note the following information when you call for service:
! Model No. / Serial No.
! Date of purchase
! Full description of problem.
