1. INTRODUCTION:
This is a high performance stand-by Uninterruptible Power Supply (UPS) designed
to protect your computer and fax machine from utility line failure. In the event of
utility failure (blackout), the UPS will rapidly transfer loads to an alternative power
source, which derives power from batteries set inside the UPS. The backup time for
a Pentium IV including 17”SVGA monitor is about 8 minutes, or 11 minutes for a
Pentium IV including 15” SVGA monitor.
2. MAIN FEATURE:
※'Green Power' based design with auto on/off function.
※Extra wide-range AVR function.
※Standard RS-232 port for monitoring function.
※Double protections for over load & short circuit.
※Auto test when turn on.
※Auto-detect input frequency 50Hz/60Hz.
3. CAUTION:
※The UPS is suitable for capacitate load, such as computer & PABX. However, it
is not suitable for inductive load, such as motor, fan, or laser printer.
※When installation, please make sure the load is not over the rated capacity of the
UPS. When blackouts happen LED will turn to red and alarm will beep if the
load is close to the rated value. Meantime, the UPS will shut down
automatically for protecting UPS itself.
※The UPS is shipped from the factory with fully charged internal batteries;
however, the batteries may lose some energy during delivery and storage. To
ensure that the UPS will provide the expected run-time, the UPS must be
charged for at least 6 hours before your first use. Please simply turn on the
UPS after installation when city power is normal, and the batteries will be
charged automatically.

4. INSTALLATION & OPERATION:
※Rear Panel
1. Power Switch.
2. Input / Output Terminals of Fax Signal.
(Either one can be input or output)
3. DB9 Connector, for monitoring With P.C.
4. Inlet of City Power.
5. Outlet (Available for IEC as shown above, & NEMA , also available for
universal type with additional charge.).
4.1 Installation
4.1.1 Connecting the UPS & city power with the original power cord of your computer.
If an extension cord must be used between the UPS and the nearest wall outlet,
use a 3-wire grounding type with rated value for at least 5 Amps.
4.1.2 Connecting outlets & phone line as shown below.
4.1.3 Turning on power switch.

4.2 Operation:
4.2.1 When the power switch is turned on, UPS will go through the procedure of self-test
(about 3-4 sec.). If test result is O.K, the green LED will be on.
4.2.2 While if it is over loaded, the UPS will alarm. Or if the battery level is low, it will
emit quick beeps for several seconds and stay in normal mode for recharging.
Please also refer to the “LED/Alarm Indication” in item 5.3.
4.2.3 Green power function
When blackout occurs, the UPS will shutdown the power automatically within 30
seconds if the output power is lower than 25W.
4.2.4 Connecting the FAX machine:
When you are connecting a FAX machine or modem with the UPS, please also
connect the phone line through the UPS. The UPS may offer protection against
damaging power fluctuations and surges that travel through the phone line.
The UPS also offers a ring on function for fax receiving when blackout occurs.
UPS power will be turned on automatically when a ringing signal exists in the
phone line, and the UPS will keep power on until the FAX machine finishes
receiving work, then the UPS will be turned-off in 30 seconds by the green power
function. In a long-time blackout situation, you won’t miss any FAX data with this
function.
On the other hand, if you need to send out a fax during a blackout, please simply
pick up the phone receiver; then the UPS will wake up and keep power on until
your fax sending work is finished.

5. INDICATION AND CONTROL
※Front Panel
5.1 Operation status LED
There are two LEDs showing the UPS status; in the normal utility power duration, Green
LED will show. While in the event of a utility outage, Red LED will flash. If the UPS is
under fault operation, Red LED will show continuously.
5.2 Audible alarm
During a utility failure or fault operation, the UPS emits beep for warning. In
back-up mode, the beeping will sound for urging user to leave computer without any
data loss.
5.3 LED/Alarm Indication:
＊Green LED, no alarm --------------------------------------------- City power normal.
＊Red LED flashing, two beeps / 4 sec. ----------------------- Backup mode.
＊Red LED flashing, quick beeping, 4 beeps / sec --------- Low battery.
＊Red LED lighting, continuous beep ---------------------- Over load
(180W up ---- Alarm & auto shut down in 30 sec.)
(210W up ---- Auto shut down immediately)
＊Red LED flashing, one beep / 4 sec. -------------------------- No load (auto shut down after 30 sec.)
＊Red + Green LEDs lighting, continuous beep ------------ Dead battery warning.
※If any abnormal condition occurs, and the UPS emit alarm continuously; please turn off
your PC in normal procedure, then turn off the UPS and wait for 3 sec, and turn on the
Switch to re-start the UPS.

6. COMPUTER INTERFACE PORT
Pin2 : AC Power Failure
Pin4 : Common GND of Pin2 & Pin5
Pin5 : UPS Battery Low
Pin6 : Turn off UPS
Pin7 : GND of Pin6
The computer interface port is diagramed above for your reference. Use Pin4
as the common of Pin2 and Pin5, Pin2 and Pin4 will become close loop from
open when the utility is fail, Pin5 and Pin4 will become close loop from open
when the battery level is low.
The UPS will shut down when the high level signal from RS-232, sustained for 3
seconds, is applied between Pin6 and Pin7.
