Safety precautions
Operation
1. Before usingthis product, please read "safety precautions" carefully to ensure correct and
safe use, and please keepthe manual properly.
2. Duringoperation, please pay attention to all warning signsand operate as required.
3. Donot use the device in direct sunlight,rain or the humid environment.
4. Thisequipment should not be installed near the heat source area or similar equipment such
aselectric heater andhot stove.
5. Asafedistanceandventilation shouldbe reservedaroundthe UPS. Please refer to the manual
for installation.
6. Please use dry cleaningtools for wipingor cleaning the UPS.
7. In caseoffire, please usethe drypowderextinguishercorrectly. Thereisariskof electric shock
if a liquid fire extinguisheris used.
Electrical safety
1. The battery life is shortened with the increase of ambient temperature. Regular battery
replacement can ensurethe UPS to work normallyand provide sufficient backuptime.
2. Battery maintenancecanonly becarried out by personnelwith battery expertise.
3. There is a risk of electric shock and short circuit in the batteries. Toavoid personal injury
causedby electric shock,please observe the following warningswhen replacingbatteries:
A. Do not wear watches, ringsor similar metal objects;
B. Use insulatedtools;
C. Wear rubber shoes andgloves;
D. Donot place metal tools or similarparts on the battery.
E. Disconnectthe load fromthe batteries before removingthe battery connectionterminal.
4. Please do not expose the battery to the fire for avoiding explosion and endangering the
safety of life.
5. Non-professionalsshould not open or damage the battery, because the electrolyte in the
battery contains dangerous substances such as strong acid, which can cause harm to the skin
andeyes.If youaccidentally touchthe electrolyte, immediatelywashit with plenty ofwater and
goto the hospital for examination.
6. Please do not short-circuitthe positive and negative poles of the battery, which may cause
electric shockor fire.
Use andmaintenance
1. The useenvironment andpreservation method have influence on the service life and
reliability of this product.Please do not useit in the following workingenvironment:
A. High,low temperature and humidplaces exceedingthe technical specifications(temperature
0-40℃, relative humidity 20%-90%).
B. Places with vibration andvulnerable to collision.
C. Places with metal dust, corrosive substance, salt andcombustible gas.
2. If it is not usedfor a longtime, the UPS(without battery) mustbe storedin a dry
environmentat the temperature range:-15-60℃.Before starting UPS, the ambient
temperature mustbe warmedto 0℃above andmaintainedfor morethan 3hours.

1. Introduction
This series of UPS is an online sine wave uninterruptible power supply system with bypass
maintenance switch, which can provide reliable and high-quality ACpower for your precision
equipment. It can be used in a wide range, from computer equipment, communication system
to industrial automatic control equipment. Because of its online design, it is different from the
backup ups. It continuously adjusts and filters the input voltage. When the power supply is
interrupted, itwill providethe backuppowerfromthe backupbattery without timeinterruption.
In case of overload or inverter failure, the UPS switches to the bypassstate and be powered by
the mains.If theoverloadiscleared,the UPS willautomaticallyswitchbackto the inverterpower
supplystate.

operatinginstructionsor the UPS performancealters in use. Reflect all faults to your dealer.
Servicing of batteries shouldbe performed or supervised bypersonnel knowledgeableof
batteries andthe precautions.
Keepunauthorizedpersonnel awayfrom the batteries. Proper disposalof batteries is required.
Refer to your local laws andregulations for disposalrequirement.
DONOTCONNECTequipmentthat could overload the UPS ordemandDCcurrent fromthe
UPS, for example:electric drills, vacuumcleaners, laser printers, hair dryer or any appliance
usinghalf-waverectification.
Storing magneticmedia ontop of the UPS mayresult in data lossor corruption.
Turnoff and isolate the UPS before cleaningit. Use only a dry cloth, never liquid or aerosol
cleaners.

2. Installation
2.1 Setup the UPS
Sep 1: UPS inputconnection
Plug the UPS into a two-pole,three-wire, groundedreceptacle only. Avoidusingextensioncords.
Step 2: UPS output connection
For socket-typeoutputs, simply connect devices to the outlets. For terminal-type input or
outputs, please follow below stepsfor the wiring configuration:
a) Removethe smallcover of the terminal block.
b) Suggest usingAWG14 or 2.1mm²power cords.
c) Upon completion of the wiring configuration, please check whether the wires are securely
affixed.
d) Put the smallcover backto the rear panel.
Step 3: Communicationconnection
Communicationport:
RS232port Intelligent slot USB port
Toallow for unattended UPS shutdown/start-upandstatus monitoring, connect the
communicationcable one end to the USB/RS232port and the other to the communicationport
of your PC. With the monitoring software installed, you can schedule UPS shutdown/start-up
and monitor UPS status throughPC.
TheUPS isequippedwith intelligent slotperfect foreither SNMP or AS400card.When installing
either SNMP or AS400cardin the UPS, it will provide advancedcommunicationandmonitoring
options.
PS.USB portandRS-232portcant workat thesame time.
Step 4: Turnon the UPS
Press the ONcombinationbuttons onthe front panel for two secondsto power on the UPS.
Note: The battery chargesfully duringthe first five hoursof normaloperation. Donot expectfull
battery run capability duringthis initial chargeperiod.
Step 5: External batteryconnection
ThisUPS doesnot include batteries.
Please connect external batteries asthe below drawing.
