the device, please read the user manual carefully, follow the operation and installation
instructions and observe all danger, warning and safety information, which is to avoid human
injury and device damage by irregular operations.
Safety Announcements
This section mainly describes the safety announcements when operation and maintenance.
For details, please refer to safety description in the relevant chapters.
Before using UPS, please read the announcements and operation instructions in this section
carefully to avoid accident.
Any device damage caused by violating the general safety operation requirements or safety
standards of design, production, and usage will be out of warranty range.
Use Announcements

Only authorized professionals are allowed to open the UPS chassis to avoid electric shock.
Otherwise, if it causes UPS failure, it is out of the guarantee range.
UPS is a class A product. When it is applied to residential building, additional measures should
be taken to prevent harassment.
 Ensure that no liquid or other foreign objects can enter into UPS.
 UPS must be grounded well.
 If UPS has to be moved, rewired or maintained, it must disconnect all electrical
connection, such as AC power, battery power, etc. to isolate power. It can't perform any
work on the UPS until UPS is powered off completely(≥10min). Otherwise, the output
may have electricity, which may cause electric shock.
 When dismantling fan, do not put fingers or tools into the rotating fan until it has stopped
working to avoid device damage or human injury.
 Don’t connect unbalance load, half-wave rectification load or inductive load in the output
of UPS, such as air-condition, blower, starter, electric drill, motor, daylight lamp, etc.
 In case of fire, use dry powder extinguisher to put out the fire. If you use liquid fire
extinguisher, it may cause electric shock.
Battery Announcements
Please use specified model battery！Non-specified model battery will lead to UPS damage.
 Only authorized professional can replace battery. When operation, take off conductive
objects, such as watch, bracelet, bangle, ring, etc., wear rubber shoes and gloves and
use tools with insulated handle.

 Don't put tools or other conductive objects on the battery.
 It's prohibited to connect the anode of battery with the cathode of 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 all electrical equipments that may easily
cause spark avoid human injury.
 Don't open or destroy 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.
ESD Protection
To prevent human electrostatic damaging sensitive components(such as circuit board), make
sure that to wear a anti-static wrist strap before touching sensitive components, and the other
end of wrist strap is well grounded.
Working Environment Requirements
 Don't install UPS where it would be exposed to direct sunlight, in rain or in moist
environments.
 Don't install UPS where it is with conductive metal dust or nearby heater.
 Generally, the working temperature is -5℃～+40℃ and the relative humidity is 0%RH～
95%RH that is with no condensation(The recommended working temperature is
20℃~25℃ and the recommended relative humidity is about 50%).
 Put UPS in the flat floor without vibration and the vertical gradient is less than 5°. Keep
good ventilation around 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 working life of inner components and
then affect the working life of UPS.
 The recommended altitude is lower than 1000m. If exceeding 1000m, it needs to
decrease the rated power according to GB3859.2-93.

2. Overview
This chapter mainly describes the features, structure and working principle, etc.
2.1 Product Intro
(1-10kVA)UPS are with all high frequency, pure online, double-conversion, intelligent features. They are
the 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 applied
to the many key business areas, such as post, finance, network, stock, railway, etc.
Features
Intelligent RS232 communication
Through the RS232 standard data port and UPS power management software, it can realize
the three remote function between the computer and UPS, monitor the running and electrical
data of UPS on the computer, perform ON/OFF operation remotely and support SNMP
network adaptor, which makes UPS be a network new member.
High input power factor
Adopt the advanced active PFC technology, which eases load in the power grid. It is the new
generation green power.
High cost performance
Adopt many kinds of power conversations and high frequency PWM technologies, which is
with high efficiency, small volume, light weight, improves the running reliability and reduces
cost.
Perfect protection
Equipped with the functions, such as output over-voltage protection, battery under-voltage
protection, input over-voltage protection, triple over-current protection, etc. and solve the
problems of the high frequency UPS, such as poor adaptability in the power grid and weak
anti-impact ability.

Low mains input voltage
Adopt the independent rapid detection technology. When the mains input voltage is 120V,
which is the lower limit, the battery still doesn't discharge. Therefore, in the mains mode, all
output power gets from the power grid, which is to ensure the battery is still in the 100%
energy storage status, reduce the battery discharge times and prolong the working life.

2.3 Working Principles
When the mains is normal, the input of (1-10kVA)UPS converts into the ±360V steady DC
voltage through PFC, which supplies power for DC/AC inverter to output steady 220V AC and
charges battery at the same time. When the mains is abnormal, the battery will boost into the
±360V DC voltage for DC/AC inverter through DC/DC.
The working principles of (1-10kVA) UPS is as follows. The DC/AC inverter adopts half bridge
structure and the DC/DC boost adopts the push-pull circuit or boost circuit. PFC is the
correction circuit for active power factor.
