1.1 “Power On” Indicator
Power On indicator illuminates when utilities’ power is normal. The indicator also
illuminates per each 4 seconds under Backup mode. Rapid flash (1 sec) means the inner
battery should be replaced again.
Attention: The internal battery have to be replaced when rapid flash occurred underAC
mode.

1.2 Outlets Design for AC Adapters
Allows two AC power adapter blocks to be plugged into the UPS without blocking adjacent
outlets.
1.3 Battery Power-Supplied Outlets
Provides instantaneous back-up power and full-time bypass protection to your equipment.
Ensure temporary uninterrupted operation of your equipment during power failure.
1.4 Full-time Bypass Protection Outlets
Provides full-time Bypass protection to your equipment. Prevents surges from traveling
through your system through unprotected peripherals.
1.5 Power button (ON/OFF/TEST/SILENCE)
The UPS can be automatically turned on while connected to the utility power. After the UPS
is turned on, it conducts a self-test and enters normal mode. Pressing the power button for 1
second under normal mode will enable the self-test function again. The silence function can
be enabled/disabled by pressing the power button for 1 second while under backup mode.
In addition, the power button can be used as the master on/off switch of your equipment by
leaving your equipment connected to UPS and switched on. To turn off the UPS, please
press power button until buzzer stops (about 2 seconds).
1.6 Circuit Breaker
Serves as an overload and fault protection. This is a critical component of the advanced
UPS surge protection circuit.
1.7 “Phone Jack” Communications Protection Ports
The UPS’s exclusive communication protection ports protect any standard modem, PBX
System or 10/100 Base T connection. This communication port can accommodate either the
phone (RJ-11) or network (RJ-45) type of jack.
1.8 USB Interface port
USB interfaces are provided for using with UPSMON software. Windows 98SE/ 2000/ ME/
XP and Windows 2003 operating systems support communication with the UPS via
UPSMON software.

2. INSTALLATION
2.1 Recharge the battery
The UPS may be used right out of the box. The battery is fully charged before it is shipped
from the factory. However, the user is encouraged to charge the battery for at least four
hours before using the UPS. Energy loss may occur during shipping or storage. To recharge
the battery, simply let UPS be plugged into an AC outlet and switch it on.
2.2 Connect the loads
Plug your primary equipment (e.g. computer, monitor and critical data storage device, etc.)
to the Battery backup outlets. Plug your peripheral equipment (e.g. printer, scanner, fax, or
audio device) to the Full-time Bypass Protection outlets. Do not plug a laser printer to the
UPS, as its power demand is much higher than typical peripherals and may cause the circuit
breaker to trip.
2.3 Connect the telephone
If you wish to protect a fax or a modem, connect the telephone cable from the wall outlet to
the “IN” jack on the UPS. Connect the telephone cable (provided) from the “OUT” jack to
the fax or modem. To protect a 10/100Base-T (UTP) network interface, obtain and use a
UTP cable to connect the “OUT” jack from the UPS to your computer.
2.4 Connect to the utility power
Plug UPS to a 2-pole, 3-wire grounding receptacle. Make sure the battery supply outlets of
the UPS do not service equipment requiring heavy electrical power
(e.g. refrigerator, air conditioner, copier, etc.).
ATTENTION: When using extension cords, make sure the total rating of the
loads is suitable.
2.5 UPS self-test
UPS will conduct a self-test each time it is turned on. In addition, the UPS will conduct a
self-test by switching the UPS on for a second when a load is connected to UPS and utility
power is normal.
2.6 Battery auto-charging
The internal battery is charged automatically when the utility power is normal.
2.7 Auto restart feature
UPS will shutdown when the battery voltage is too low, and reactivate automatically when
the utility power is normal.
2.8 Overload (continuous alarm)
When the UPS is working under overload condition (the connected loads exceed the
maximum rated capacity), the UPS will emit a continuous alarm to warn of the overload
condition. In order to protect the unit and the loads, the UPS will automatically turn off.
Please disconnect any non-essential devices form the UPS to eliminate the overload alarm.

2.9 Optimal battery status
To maintain the optimal battery status, leave UPS plugged in and switched on at all times.
2.10 No load Shutdown feature
The UPS is equipped with a no load shutdown function. When the UPS senses no load, the
unit will automatically shutdown after 3 minutes.
3. OPERATION
3.1 Simple test
It is recommended that the user perform a simulation test when using the UPS for the first
time or when adding an additional piece of equipment to the UPS. To conduct a simulation
test: First, switch the UPS on and wait for the power indicator to light up, then simply
unplug the UPS to simulate a power failure.
3.2 Check the power requirement of your equipment
3.2.1. Make sure the total power of your equipment does not exceed the rating capacity.
3.2.2. Make sure the equipment you plug into the Battery Power-Supplied outlets does not
exceed the total power that can be handled by the capacity of the UPS. Otherwise, overload
may occur and cause the circuit breaker to trip. If the power requirement of your equipment
differs from VA, convert the requirement power into VA by doing the calculations 3.2.3:
3.2.3. If the power requirement of your equipment is not listed in VA, and the power factor
is uncertain, assume the power factor of the load is .50 (worst case.) Multiply your load’s
total wattage by two for an estimated VArating.
3.3 Limited rating power of UPS
When utility power failure occurs, the battery power outlets will supply power to your
equipment from its battery. The buzzer will beep once every 4 seconds. Be sure that your
equipment is running under the maximum power limit. When utility power is restored,
perform the self-test to make sure UPS works properly.

4. SOFTWARE AND COMPUTER INTERFACE
4.1 Power Monitoring Software
The UPSMON software (or other compatible power monitoring software) uses a USB port
interface to perform monitoring functions. Furthermore, it provides an orderly shutdown of
a computer in the event of power failure. Moreover, UPSMON displays all the diagnostic
symptoms on the monitor, such as Voltage, Frequency, Battery level and so on. The
software is compatible with Windows 98SE /2000/ ME/ NT/ XP/ 2003 and other operating
system.
4.2 Interface Kits
A series of interface kits is available for operation systems that provide UPS monitoring.
Each interface kit includes the special interface cable required to convert status signals from
the UPS into signals which individual operating systems recognize. The interface cable
must be connected to REMOTE PORT at the UPS side, and USB port at the computer side.
For other installation instructions and features please refer to READ.ME file.
CAUTION: Use only factory supplied or authorized UPS monitoring cable!
4.3 The characteristics of computer interface port
The computer interface port has the following characteristics:
The communication port on the back of the UPS may be connected to a host computer. This
port allows the computer to monitor the status of the UPS and control the operation of the
UPS in some cases. Its major functions normally include some or all of the following:
zTo broadcast a warning when power fails.
zTo close any open file before the battery is exhausted.
zTo turn-off the UPS.
5. BATTERY MAINTENANCE AND REPLACEMENT
5.1 Battery maintenance
For preventive maintenance, keep the area around the UPS clean and clutter free. Keep the
UPS at an ambient temperature of 25℃(77℉). It is recommend that the battery charges for
24 hours after a long period of storage.
5.2 Battery replacement
The battery should be replaced if the Power-on indicator flashes. To verify if the battery
needs to be replaced, conduct a self-test by pressing the Power button. If the Power-on
indicator continues to flash, replace the inner battery according to the following procedure.
