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.

3. System Description
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, regulated AC
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
DS-I 1-3k UPS User Manual
System Description
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 15-25C.
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.

Battery Maintenance
8. Battery maintenance
1-3KVA UPS only requires minimal maintenance. The batteries used for standard models are
value regulated, sealed lead-acid, maintenance free battery. When it being connected to the
utility power, whether the UPS is turned on or not, the UPS keeps charging the batteries and
also offers the protective function of overcharging and over-discharging.
The UPS should be charged once every 4 to 6 months if it has not been used for a long
time.
In the regions of hot climates, the battery should be charged and discharged every 2
months. The standard charging time should be at least 12 hours.
Under normal conditions, the battery life lasts 3 to 5 years. In case if the battery is found
in bad condition, earlier replacement should be made.
Battery replacement should be performed by qualified personnel.
Replace batteries with the same number and same type of batteries.
Do not replace the battery individually. All the batteries should be replaced at the same
time following the instructions of the battery supplier.

2) Use rubber gloves and boots, use tools with insulated handles.
3) If it is necessary to replace any connection cables, please purchase the original
materials from the authorized distributors or service centers, so as to avoid overheat
or spark resulting in fire due to insufficient capacity.
4) Do not dispose of batteries or battery packs in a fire. The batteries may explode.
5) Do not open or mutilate batteries, released electrolyte is highly poisonous and
harmful to the skin and eyes.
6) Do not short the positive and negative of the battery electrode, otherwise, it may
result in electric shock or fire.
7) Make sure that there is no voltage before touching the batteries. The battery circuit is
not isolated from the input potential circuit. There may be hazardous voltage
between the battery terminals and the ground.
8) Even though the input breaker is disconnected, the components inside the UPS are
still connected with the batteries, and there are potential hazardous voltages.
Therefore, before any maintenance and repairs work is carried out, switch off the
breaker of the battery pack or disconnect the jumper wire of connecting between the
batteries.
9) Batteries contain hazardous voltage and current. Battery maintenance such as the
battery replacement must be carried out by qualified personnel who are
knowledgeable about batteries. No other persons should handle the batteries
9.2 Battery Replacement Procedures
1) Turn off UPS completely.
2) Remove covers from the UPS.
3) Disconnect the battery wires one by one.
4) Remove metal bars which are used to fasten batteries.
5) Replace batteries one by one.
