1. INTRODUCTION (for long run models: SS-750L/1000L/1500L/2000L only)
1.1 Overview:
The series UPS is an advanced Line-Interactive Uninterruptible Power System
which produces pure sine wave power to your equipment; unlike the traditional
off-line UPS, the series provide very short transference when blackouts happen,
and zero transference from AC mode to battery mode or from battery mode to
AC mode. The voltage regulation performance of the series is similar to an
On-line UPS; however, the series provide efficiency over 98% under normal
power condition. Two charge modes, quick charge and trickle charge, are
provided to maintain the batteries in the best condition.
1.2 Battery replacement warning
The self-test function (by pushing the button) will inform you with an alarm
when the batteries are weak and require replacement.
1.3 DIP switches
The DIP switches allow you to adjust the UPS for different line voltages and
frequencies in different areas. It also allows you to enable the green power
function to shut down the UPS automatically if the load is less than 25W, and then
to extend the battery life.
1.4 Communication interface
A communication interface port for sensing input voltage, output voltage, battery
capacity, output power level, and UPS statuses are provided; through this port, you
can remote control the UPS for turning on and off by customized schedule and
setting the auto-test procedure.

2. MAIN FEATURE:
Line-Interactive structure.
Microprocessor based design.
‘Green Power’ design with auto on/off function.
RS-232 interface for communication.
Protection for overload, short circuit, & over heat.
Pure sine wave output.
Zero Transference.
3. CAUTION:
The UPS is designed to power computer loads and the associated peripheral devices,
such as monitors, modems, external H-Disk drivers, etc. To ensure the performance
of the UPS, Do Not load the UPS with laser printer, motor, or any type of inductive
load.
Connecting the UPS to a two-pole, three-wire grounding mains receptacle.
Connection with any other type of receptacle may result in a shock hazard and may
violate local electrical codes.
Do not allow water or any foreign object to get inside the UPS. And do not put objects
containing liquid on or near the unit.
Keep UPS away from fire or heating sources.

4. INSTALLATION & OPERATION:
4.1 Installation
Inspecting the packing carton for damage that may have occurred while in transit.
Immediately notify the carrier and place of purchase if any damage is found. Retain the
package for future use.
Plugging the power cord to a 3-wire grounding receptacle. If an extension cord must
be used between the UPS and the nearest wall outlet, use a 3-wire grounding type
rated for at least 20 Amps.
Connecting your equipment to the UPS. To ensure that your computer equipment will
be protected during a utility failure, it is important to make sure that the maximum
power need from the equipment is not over the rated capacity of the UPS. Red LED
will lighted up and alarm will beep if the load is over the rated value. Meantime, if the
overload is severe, the UPS will shut down immediately for protecting UPS itself.
4.2 Operation
4.2.1 After installation with normal city power, the UPS will charge the battery automatically,
and the status LED blinks green every 2 seconds. Please push the button about one
second on the front panel, then the UPS will give power to the outlets after a short-time
of self-test.
4.2.2 Pushing the button for 4 seconds, the UPS will turn off the power on the outlets. But, the
UPS will keep charging if city power is normal. To stop the charging, please pull out the
power cord to shut down the UPS completely.
4.2.3 During a blackout, push the button for entering idle mode (Ref. Indication Table),
then push again for one second, and the UPS will be turned on and enter into
backup mode. To turn off the power from UPS; please push the button for 4
seconds, then UPS status LED will blink orange every 2 seconds, wait for 5
seconds, and UPS will turn off the power automatically.
4.2.4 In idle mode, UPS will turn off the power automatically within 12 seconds during a
utility failure; while UPS will keep charging the batteries if the utility power is
normal. When utility power is normal, please pull out the power cord if you want
to turn off the UPS completely.
4.2.5 When “Green Power” function is enabled, the UPS will turn off the power within 30
seconds after blackout occurs with the power consumption lower than 25W.
4.3 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 when the power is off. 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 by the green power function. In a long-time blackout situation, you won’t
miss any FAX data by this function.

5. INDICATION AND CONTROL
5.1 Battery level and load level LEDs
The battery level LEDs show the voltage level both in back-up mode and in normal
mode. When the LED indicates 20% of the capacity in back-up mode, it means
that the UPS is going to shut down; for the length of backup time left, it will depend
on the load. While when all five LEDs light in normal mode, it means that the
battery is fully charged.
The load level LEDs show the percentage of added load by the UPS rated capacity.
When all five LEDs light, the UPS is over loaded.
5.2 Operation status LED
The status LED shows the UPS status, in the normal utility power duration, LED shows
Green. In the event of a utility outage, LED shows Orange. If the UPS is under fault
operation, LED shows Red.
5.3 Audible alarm
During a utility failure or fault operation, the UPS emits beep for warning. In back-up
mode, the beeping can be silenced by pushing the button. However, the warning of
low battery will still sound for urging user to leave computer without any data loss.
Basic Indication Table:
LED ALARM PERIOD STATUS
Green No Beep One flash every 2
sec. Utility Good
Orange No Beep One flash every 2
sec. Utility outage
Idle mode
Red No Beep One flash every 2
sec. Timer on, refer to Item 5.6
Green No Beep Continuously Normal
(Utility good)
One beep every 4
sec. Back-up
(No load)
Orange Yes, can be silenced
2 beeps every 4
sec. Back-up
(Loading)
Orange No, can Not be
silenced 4 beeps per sec. Battery Low
Normal/
Back-up
mode
Red Yes 8 beeps per sec. Battery NG.
5.4 Auto self-test Function:
In normal mode of UPS, turn on your computer and push the button on the front panel
for self-test. The UPS will simulate a power outage and transfer your load to the
UPS battery. If low battery warning sounds during the test, it means that the battery
set is weak and requires extended recharge. If battery NG warning sounds, it means
that the battery set is damaged and requires replacement.

will begin to run, and the load will be turned off by the shutdown/wake up schedule.
During the period of turn off to the next turn on, the status LED blinks red every 2
seconds. .
5.7 Reset the UPS
If any abnormal condition occurs, and the item 4.2.1 ~ 4.2.4 can not be executed,
please push the button for at least 10 sec. until the status LED becomes orange,
then the UPS is reset.

6. COMMUNICATION INTERFACE:
The UPS provides both computer interfaces, smart software (RS-232) and dry
contact (DB-9); by using different software and cable, the UPS shows different
monitoring function.
6.1 The definition and setup for RS-232 is as following:
Baud Rate : 2400 dps
Data Length : 8 bits
Stop Bit : 1 bit
Parity : None
Pin #6 : RS-232 data Tx out.
Pin #7 : Common of Pin #6 and Pin #9
Pin #9 : RS-232 data Rx In
6.2 The definition and setup for DB9 (optional) is as following:
Pin #2 : AC Power Failure
Pin #4 : Common GND of Pin #2 & Pin #5
Pin #5 : UPS Battery Low
Pin #6 : Turn off UPS
Pin #7 : GND of Pin6
The interface with computer is diagramed as above for your reference. Use Pin #4 as the
common of Pin #2 and Pin #5, Pin #2 and Pin #4 will become close loop from open when
the utility fails, Pin #5 and Pin #4 will become close loop from open when the battery level
is low.
The UPS will shut down itself when the high level signal from RS-232, sustained for
3 seconds, is applied between Pin #6 and Pin #7.
