1 Safety Precautions
1.1 Precautions for Operating a UPS
When operating a UPS, observe the following precautions:
All repairs and operations should be performed by authorized service personnel only.
Ensure all power is disconnected before performing installation and service.
Components inside an uninterruptible power system (UPS) are not operable. Do not open
the UPS cover. Otherwise, electric shocks may occur, and the resulting UPS faults are
beyond warranty scope.
Before moving or reconnecting a UPS, disconnect the AC input and batteries and wait
about 5 minutes until the UPS is powered off. Otherwise, electric shocks may occur.
To ensure human safety and normal UPS operation, the UPS must be properly grounded
before use.
To ensure that a UPS has a long service life and trusted reliability, do not place it in the
following places for a long time:
−Places where the temperature and relative humidity are outside the specifications
(temperature: 0–40°C, relative humidity: 0%–95%)
−Places in direct sunlight or near heat source
−Places where a UPS is susceptible to vibrations and shocks
−Dusty places, or places where corrosive substances, salts, or flammable gases are
present
Please keep the air vents of the UPS unobstructed. Poor ventilation will increase the UPS
internal temperature, which will shorten the lifetime of the UPS components and even
the UPS.
Liquid and other irrelevant objects are strictly prohibited inside the UPS.
In case of fire, use dry chemical fire extinguisher to put out the fire. Using fluid fire
extinguisher may cause electric shock.
The UPS input power cable is recommended to be less than 2 meters.
Smoking and fire are forbidden within 3 meters around a UPS.

1.2 Precautions for Operating Batteries
When operating batteries, observe the following precautions:
Do not open or damage the battery, as the battery electrolyte is harmful to human skin
and eyes. If electrolyte comes into contact with the skin, wash the affected area with
plenty of clean water immediately and go to the hospital for a check.
To prevent explosion and ensure human safety, do not dispose of batteries in fire.
Before operating batteries, get tools insulated, and take off metal articles, such as
watches and rings.
To prevent batteries from starting a fire, do not short-circuit battery terminals.
To avoid damages, transport and hold batteries gently.
1.3 Environment Requirements
Only qualified personnel are allowed to disassemble a UPS. Removed components must be
operated by qualified disposal centers.
1.4 Other Requirements
A UPS can be used to serve resistive-capacitive loads (for example, computers), resistive
loads, and micro-inductive loads. It is recommended that a UPS not be used for pure
inductive loads and pure capacitive loads (for example, motors, air conditioners, and
printers).
Before using a UPS to support the following equipment, consult Huawei for special
requirements on the application, configuration, management, and maintenance of the
UPS:
−Life support equipment
−Facilities such as lifts where adequate care has to be taken to avoid any fatal
eventuality endangering human life

2 UPS Overview
2.1 Features
Intelligent Communication Over RS232 Ports
The power management software installed on computers, over RS232 ports, remotely
monitors the operating status and electrical parameters, and communicates with the UPS.
High Input Power Factor
The UPS is a new generation of green power supplies. It uses the active power factor
correction (PFC) technology to save power and harmonic pollution.
High Performance
The UPS is small, light, efficient, and reliable.
Effective Protection
The UPS is protected against input overvoltage, output overvoltage, and battery undervoltage,
and provides triple protection against overcurrent. It overcomes the problems of poor
adaptability to electric grids and weak resistance to current impact.
Wide Input Voltage Range
The UPS2000 uses a unique quick detection technology so that it can adapt to a wide AC input
voltage range. Even when the AC input voltage fluctuates in a wide range, the UPS2000 still
powers loads in normal mode. This ensures that all power supplied to loads is from the power grid
and storage batteries maintain 100% battery amount all the time, reducing their charge and
discharge cycles and extending their lifespan.
2.2 Output Capacity
Table 2-1 describes the UPS output capacity.

2.4 Working Principles
The UPS consists of a PFC rectifier, an inverter, a battery charger (BC), a DC-DC converter,
batteries, and a static switch. Figure 2-5 shows the UPS block diagram.
Figure 2-5 UPS block diagram
The UPS works in any of the following three modes:
Normal mode
The PFC rectifier boosts AC input and converts it into stable DC power for the inverter, and
the battery charger utilizes energy from the AC input and regulates it to continuously charge

the batteries, Then the inverter converts the DC power into stable AC power for powering
loads.
Battery mode
When theAC input is failure, the DC to DC converter boosts the DC power supplied by
batteries. Then the inverter converts the DC power into stable AC power for powering loads.
Bypass mode
When the UPS is overloaded, overheated, or faulty, and the bypass is normal, the power
supply automatically transfers to the bypass.

Installation Environment
The UPS installation environment should meet the following requirements:
The temperature and humidity are within the range of 0–40°C and 0%–95% respectively.
Install the UPS in an environment with good ventilation and free of dust, volatile gas,
salt, and corrosive materials. Keep the UPS far away from water, heat source, flammable
and explosive substances. Avoid direct sunlight.
The optimal operating temperature for batteries is 20–30°C. Operating at temperatures lower
than 20°C will shorten the battery backup time, and operating at temperatures higher than
30°C will shorten the battery lifespan.
Installation Clearance
The UPS installation clearance should meet the following requirements:
Maintain a clearance of at least 60 mm from the front panel and rear panel of the UPS to
the wall or adjacent equipment.
Keep the air inlets unobstructed on the front panel and rear panel of the UPS to facilitate
ventilation and heat dissipation. Otherwise, the UPS internal temperature will rise, which
will shorten the lifetime of the UPS.
