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“ ”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 faults 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 surge current from

the UPS, for example: electric drills, vacuum cleaners, hair dryer, motors and so on.
DO NOT CONNECT equipment that is life related, for example: medical equipment, elevator
and so on.
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.
1.2 Features
The UPS features include:
Providing more high efficient AC power, compared with the previous generation
Full digital control technology based on DSP to achieve high reliability and power
function
Fan speed can be auto conditioned according to the loads, input voltage or working
mode
Digitally controlled charger current and voltage, compared with the previous generation
which is fixed in hardware
Super high power density
Failure waveform record function helps to solve problem quickly

1.5 System Description
Fig 1- 3: UPS system
1.5.1 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.
1.5.2 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 sinewave 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.
1.5.3 Inverter
In normal operation, the inverter utilizes the DC output of the power factor correction circuit
and inverters it into precise, regulated sinewave 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, regulated AC output power.

1.5.4 Battery Charger
The battery charger utilizes energy from the DC bus and precisely regulates it to
continuously charge the batteries. The batteries are being charged whenever the UPS is
connected to utility power.
1.5.5 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.
1.5.6 Battery
The 6KS/10KS Standard includes value regulated, sealed lead acid, maintenance free
batteries inside. To maintain battery design life, operate the UPS in an ambient temperature
of 15-25°C.
1.5.7 Static 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. To
manually transfer the connected load from the inverter to bypass, press the “ + ”
button once.
NOTICE: The bypass power path does NOT protect the connected equipment from
disturbances in the utility supply.
1.6 UPS Working Mode
Normally UPS working mode include normal mode, bypass mode, battery mode, ECO mode,
frequency converter mode, self aging mode.
Normal Mode
Shown as Fig 1-4, rectifier supply DC supply to inverter, the load is feed by inverter. Charger
is charging the battery.

Fig 1- 4: Normal Mode
Static Bypass Mode
If inverter is failure or overload, UPS will transfer to bypass mode. Or press“ + ”to
transfer to bypass mode in normal mode. The load is feed by input power directly, and UPS
can not protect load from surge. Shown as Fig 1-5.
Fig 1- 5: Bypss Mode
Battery Mode
If input power is failure when in normal mode, UPS will transfer to battery mode. In this
mode, the battery provide power to inverter. Shown as Fig 1-6.
NOTICE: press“ + ”in battery mode will shutdown UPS completely.
Fig 1- 6: Battery Mode
ECO Mode (only available for single unit)
When UPS works in ECO mode, load is feed by bypass. Inverter is standby, charger is
working normally. The efficiency is up to 98%, but UPS can protect the load from surge
disturb. If input power is failure, UPS transfer to battery mode. Shown as Fig 1-7.
