Warning: This is a product for commercial and industrial application in the second
environment-installation restrictions or additional measures may be needed to
prevent disturbances.
NOTICE：
This is a product for restricted sales distribution to informed partners. Installation restrictions or
additional measures may be needed to prevent radio interference.
Operated the UPS in an indoor enviroment only in an ambient temperature range of
0-40C(32-104F). Install it in a clean environment, free from moisture, flammable liquids,
gases and corrosive substance.
This UPS contains no user-serviceable parts except the internal battery pack. The UPS on/off
push buttons do not electrically isolate internal parts. Under no circumstance attempt to gain
access internally, due to the risk of electric shock or burn.
Do not continue to use the UPS if the panel indications are not in accordance with these
operating instructions or the UPS performance alters in use. Refer all fault to your dealer.
Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the precautions. Keep unauthorized personnel away from the batteries. Proper
disposal of batteries is required. Refer to your local laws and regulations for disposal
requirement.
DO NOT CONNECT equipment that could overload the UPS or demand DC current from the
UPS, for example: electric drills, vacuum cleaners, laser printers, hair dryer or any appliance
using half-wave rectification.
Storing magnetic media on top of the UPS may result in data loss or corruption.
Turn off and isolate the UPS before cleaning it. Use only a soft cloth, never liquid or aerosol
cleaners.

2. Introduction
Congratulations on your choice of the uninterruptible power system (UPS), the UPS comes in
nominal power ratings of 1000VA, 2000VA and 3000VA. It is designed to provide conditioned
power to microcomputers and other sensitive electronic equipment.
When it is generated, alternating current is clean and stable. However, during transmission and
distribution it may be subject to voltage sags, spikes and complete power failure that may
interrupt computer operations, cause data loss and even damage equipment. The UPS
protects equipment from these disturbances.
The UPS is a compact, on-line UPS.An on-line UPS continuously conditions and regulates its
output voltage, whether utility power is present or not. It supplies connected equipment with
clean sine-wave power. Sensitive electronic equipment operates best from sine-wave power.
For ease of use, the UPS features a LCD display to indicate all information for UPS, and
provide kinds of function buttons.

Input Output
3.1 Transient Voltage Surge Suppression (TVSS) and EMI/FRI Filters
These UPS components provide surge protection and filter both electromagnetic interference
(EMI) and radio frequency interference (RFI). They minimize any surge or interference present
in the utility line and keep the sensitive equipment protected.
3.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC power
to regulated DC power for use by the inverter while ensuring that the waveform of the input
current used by the UPS is near ideal. Extracting this sine-wave input current achieves two
objects:
The utility power is used as efficiency as possible by the UPS.
The amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being
protected by the UPS.
3.3 Inverter
In normal operation, the inverter utilize the DC output of the power factor correction circuit and
inverters it into precise, regulated sine-wave AC power. Upon a utility power failure, the inverter
receives its required energy from the battery through the DC-to-DC converter. In both modes of
operation, the UPS inverter is on-line and continuously generating clean, precise, regulatedAC
output power.
3.4 Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to
continuously float charge the batteries. The batteries are being charged whenever the UPS is

connected to utility power.
3.5 DC-to-DC Converter
The DC-to-DC converter utilizes energy from the battery system and raises the DC voltage to
the optimum operating voltage for the inverter. The converter includes boost circuit which is
also used as PFC.
3.6 Battery
The standard model includes value-regulated, non-spillage, lead acid batteries inside. To
maintain battery design life, operate the UPS in an ambient temperature of 15-25C.
3.7 Dynamic Bypass
The UPS provides an alternate path for utility power to the connected load in the unlikely event
of a UPS malfunction. Should the UPS have an overload, over temperature or any other failure
condition, the UPS automatically transfers the connected load to bypass. Bypass operation is
indicated by an audible alarm and illuminated amber Bypass LED.
NOTICE：The bypass power path does NOT protect the connected equipment from
disturbances in the utility supply.
