1 Safety Description
This chapter introduces the safety announcements. Prior to performing any work on the UPS,
please read the user manual carefully to avoid human injury and device damage by irregular
operations.
1.1 Safety Announcements
This section introduces the safety announcements that must be complied with and pay
special attention while installing, using, maintenance and other relative operations.
Before operating, please read the announcements and operation instructions in this section
carefully to avoid accident.
The DANGER, WARNING, CAUTION, etc. in the manual are not all the safety
announcements that you must abide by, they are just the supplements for the safety
announcements during operating.
Our Company does not undertake the responsibility caused by violating common safety operation
requirements or the safety standard of design, manufacture and use.
1.1.1 Safety Instructions
There exists high temperature and high voltage inside the UPS. During using, please strictly
comply with all warnings and operation instruments on the UPS and in the user manual.

1 Safety Description

The UPS is class C3 device. If it is used in residential purpose, it may cause wireless
interference. User should take actions to avoid the interference.
No liquid or other objects are allowed to enter the UPS.
UPS must be well grounded.
In case of fire, please use dry power fire extinguisher. If using liquid fire extinguisher, it
may cause electric shock.
1.1.2 Use Announcements for Battery
Please use specified battery. Non-specified battery will damage the UPS.
Only authorized professional can replace battery. Do not wear conductive objects, such
as watches, bracelets and rings during operating. Wear rubber shoes and gloves and use
tools with insulated handle.
Don't put tools or other conductive objects on the battery.
It is prohibited to short the positive pole and negative pole of the battery or connect them
reversely, which is to avoid fire or electric shock.
Before connecting or disconnecting the battery terminals, disconnect charger first.
The battery must be with the same type, model and manufacturer.
Battery should be kept away from fire source or other electrical equipments that may
easily cause spark to avoid human injury.
Don't open or destroy the battery. The electrolyte in the battery includes some dangerous
objects, such as strong acid, which will be harmful to skin and eyes. If it is careless to
touch the electrolyte, clean it by a lot of water immediately and then check it in the
hospital.
The waste battery should be disposed according to the local regulations.

1.1.3 Anti-Static Protection
The static generated by human bodies may damage the electrostatic-sensitive components
on PCB. Before touching the sensitive component, please wear anti-static rings and well
connect the other end of the anti-static rings to ground.
1.2 Operation and Maintenance Requirements
Only authorized professionals are allowed to open the UPS chassis, or it may cause electric
shock and the caused UPS fault is out of the guarantee range.
If UPS needs to be moved, rewired or maintained, disconnect all electrical connection,
such as AC power, battery power, etc. to isolate power input. Do not do any work on the
UPS until it is powered off completely (≥10min). Otherwise, the output may exist
electricity, which may cause electric shock.
When dismantling fan, do not put fingers or tools into the rotating fan to avoid device
damage or human injury.
1.3 Environment Requirements
Do not put the UPS in the environment where has inflammable, explosive gas or smog, do
not do any operation in this environment.
Do not use the UPS in the place where has direct sunshine, rain or wet.
The normal work temperature of UPS is -5℃~40℃, relative humidity: 0%-95%, with no
condensation (recommended work temperature is 20℃~25℃, humidity is about 50%).
Put the UPS in the flat floor without vibration and the vertical gradient is less than 5°.
Keep good ventilation around the UPS. The clearance between the rear or the side of
UPS and adjacent devices or wall should be at least 300mm~500mm. Poor ventilation

will rise temperature inside UPS, which will reduce the service life of inner components
and even affect the life span of the UPS.
The UPS must be used below 2000m. If the altitude exceeds 2000m, it needs to
decrease the rated power according to IEC62040-3:2011 to use.

2 Overview
This chapter mainly introduces the UPS's model meaning, features, structure, work principle, etc.
2.1 Product Intro
UPS is whole high frequency, pure online, double-conversion, smart product. The system is
perfect power security for file server, enterprise server, center server, micro-computer,
concentrator, telecom system, data center and others that require high quality power
protection. They are widely used in many key business areas, such as post, finance, network,
stock, railway, etc.
2.1.1 Features
Completely digitalized smart control
10kVA-20kVA UPS support three-in and three-out mode UPS, three-in and one-out mode
UPS, one-in and one-out mode UPS.
30kVA-40kVA UPS support three-in and three-out mode UPS, three-in and one-out mode
UPS.
The UPS can monitor the grid frequency (50Hz/60Hz) and self-adapt the frequency. The
output voltage can be set to 208V/220V/230V/240V, which makes the use more flexible.
Energy conservation and high efficiency
Adopts three-level inverter technology and PFC control technology, the output voltage wave
is perfect and the whole efficiency can be 96%, the input power factor is greater than 0.99,
which greatly improves the use ratio of electric energy and reduces the load of power grid.
Smart fan speed control
The fan speed is adjusted automatically in accordance with the load status, which prolong
fan life and reduce noise.

2 Overview

ECO energy conservation mode design
The UPS is designed with ECO energy conservation mode. When the grid is good, if the
UPS operating in this mode, the bypass prior to output, and the efficiency can be 99%.When
the bypass voltage or frequency out of normal range and cannot satisfy the user’s power
supply requirement, it will switch to inverter output, which guarantee the reliability of power
supply and also, save energy.
Low mains input voltage
Adopt the independent rapid detection technology. When output load is small, even the
battery voltage is 80V, which is the main slow limit, the battery still doesn't discharge.
Therefore, in the mains mode, all output power gets from the grid, which is to ensure the
battery in 100% energy storage status, and at the same time, reduce the battery discharge
times and prolong the service life.
Tower-mounting and rack-mounting
User can select tower-mounting or rack-mounting the UPS according to use space, the LCD
also can display corresponding direction on the basis of placement mode.

3. If the BMD and EPO detection function won't be used, please short the port by equipped 4P
terminal. When the function needs to be used, dismantle the short wire of BMD or EPO port and
connect it with corresponding status signal input of maintenance bypass breaker or EPO.
Only when the bypass maintain switch state detection (BMD) and EPO port are all shorted
respectively, the UPS can work normally.
If BMD port is disconnected, the UPS will turn to bypass power supply, and at the same
time, the LCD shows BMD fault. Once the port recovers short connection, the fault will
be removed automatically.
If the EPO port is disconnected, the UPS will shut down all inverter and bypass output
and at the same time, the LCD shows EPO fault. The UPS needs to be power down
completely and short connect the EPO port, the fault will be removed automatically.
