    The following items are inside the box:

Remove the UPS from its package and inspect it for damage that

may have occurred during shipping. If any damage is discovered,

re-pack the unit and return it to the place of purchase.

2)、Connect to Utility Power

Connect AC power cord to utility power. Then, the UPS will start to

charge inside battery. For best result, charge the battery for 6 hours

prior to initial use.

3)、Plug in Equipment

Plug your equipment to Battery Backup Outlets on the rear panel of

the UPS.

NOTE: Make sure that the UPS is powered on to protect all

important devices from data loss during power failure.

CAUTION: NEVER connect a laser printer or scanner to the

battery backup outlets of UPS. The equipment may draw

significantly power to overload the UPS.


1)、Turn On the UPS

To turn on the UPS unit, press the power switch lightly. Then, the

LED will light up.

2)、Turn Off the UPS

To turn off the UPS unit, press the power switch again. Then, the

LED will go off.

3)、Cold Start Function

When the UPS is off and there is no power utility, it's still possible to

cold start the UPS unit to power the loads.

4)、Free Software Download (Option)

Go to the website and

download the ViewPower software. Follow on-screen instruction to

install the software. When your computer restarts, the monitoring

software will appear as an orange plug icon located in the system

tray, near the clock.

Front Panel


A)、Battery backup outlets:

Plug sensitive equipment into battery backup outlets. Battery

power is automatically provided in case of a power outage.

B)、AC input

C)、Fuse (option):

The fuse will be burned out if an overload condition forces the UPS

to disconnect itself from utility power.

D)、USB com. port (option):

To monitor the UPS status, such as unattended UPS shutdown and

start-up, by using download software, please connect the UPS and

PC with USB cable included.

E)、Modem/Phone line surge protection (option):

Connect a single modem or phone line into surge-protected “IN”

outlet on the back panel of the UPS unit. Connect from “OUT”

outlet to the computer with another phone line cable.


Battery mode:

When the UPS is in battery backup mode (battery mode), the

green LED will flash and the UPS sounds an audible alarm every 10 seconds.

Low battery:

When the UPS is in battery backup mode (battery mode) and the

battery energy begins to run low, the UPS will beep every second.


When the UPS is overloaded, the UPS will beep every 0.5 second

to warn an overload condition.


When there a UPS fault occurs, the UPS will continuously beep.


SAVE THESE INSTRUCTION-This manual contains important instructions that should be followed during installation and maintenance of the UPS and batteries.

1)This UPS utilizes voltage that may be hazardous. Do not

attempt to disassemble the unit. The unit contains no user

replaceable parts. Only factory service personnel may perform repairs.

2) This pluggable type A equipment with battery already installed

by the supplier is operator installable and may be operated by laymen.

3) The mains socket outlet that supplies the UPS shall be

installed near the UPS and shall be easily accessible.

4) During the installation of this equipment it should be assured

that the sum of the leakage currents of the UPS and the

connected loads does not exceed 3.5mA.

5) Connection to any other type of receptacle other than a

two-pole, three-wire grounded receptacle may result in shock

hazard as well as violate local electrical codes.

6) In the event of an emergency, press the "OFF" button and

disconnect the power cord from the AC power supply to

properly disable the UPS.

7) Do not allow any liquids or any foreign object to enter the

UPS. Do not place beverages or any other liquid-containing

vessels on or near the unit.

8) This unit intended for installation in a controlled environment

(temperature controlled, indoor area free of conductive

contaminants). Avoid installing the UPS in locations where

there is standing or running water, or excessive humidity.

9) Do not plug the UPS input into its own output.

 10)Do not attach a power strip or surge suppressor to the UPS.

11) Do not attach non-computer-related items, such as medical

equipment, life-support equipment, microwave ovens, or

vacuum cleaners to UPS.

12)Do not dispose of batteries in a fire as they may explode.

13) A battery can present a risk of electrical shock and high short

circuit current. The following precautions should be observed

when working on batteries:

(1) Remove watches, rings, or other metal objects from the hands.

(2) Use tools with insulated handles.

(3) Wear rubber gloves and boots.

(4) Do not lay tools or metal parts on top of batteries.

(5) Disconnect charging source prior to connecting or

dis-connecting batteries terminal.

 14)Internal battery voltage is 12VDC.Sealed, lead-acid, 6-cell


15) Servicing of batteries should be performed or supervised by

personnel knowledgeable of batteries and the required

precautions. Keep unauthorized personnel away from batteries.

16) When replacing batteries, replace with the same number and

type of sealed lead-acid battery.

17) Do not open or mutilate the battery or batteries. Release

electrolyte is harmful to the skin and eyes. It may be toxic.

18) Attention, hazardous through electric shock. Also with disconnection

of this unit from the mains, hazardous voltage still

may be accessible through supply from battery. The battery

supply should be therefore disconnected in the plus and minus

pole at the connectors of the battery when maintenance or

service work inside the UPS is necessary.

19) To reduce the risk of overheating the UPS, do not cover the

UPS' cooling vents and avoid exposing the unit to direct

sunlight or installing the unit near heat emitting appliances such

as space heater or furnaces.

20) Unplug the UPS prior to cleaning and do not use liquid or spray




Install the UPS in a protected area that is free of excessive dust

and has adequate air flow. Place the UPS away from other units at

least 20 cm to avoid interference. For best performance, keep the

indoor temperature between 0° C and 40° C.


All connected equipment should be turned off, then disconnect

from the UPS to avoid battery drain. Unplug the UPS from the wall

outlet. Then turn off the UPS for storage. Store the UPS unit

covered and upright in environments where the ambient

temperature is -20 C to 50 C with its battery fully char
