1.3 Primary Functions and C aracteristics
1 ． Intelligentized RS232 communication function: With RS232 standard
data interface and UPS power management software, realize three
remote-control functions etween computer and UPS, computer
supervises UPS operation and electric parameters, and realize
long-distance power on/off function, as well as supporting SNMP
network adaptor (outlaid, connecting UPS through RS232 interface),
which ena les UPS to directly ecome network fresh lood.
2 ． High input power factor: Adopt advanced active PFC technique, which
alleviates load on electric network and represents green power supply of
new generation.
3 ． High performance-price ratio: Adopts multiple power transfer and high
frequency PWM technique, high efficiency, small size and light weight as
well as improving operational relia ility and reducing manufacturing cost,
which lowers the cost of the system design for customers.
4 ． Perfect protection function: Possess such functions as output
low-voltage protection, attery low-voltage protection, input low-voltage
protection and triple overflowing protection, etc and overcome previous
defects such as high frequency UPS' poor adapta ility and weak
resistance to shock for electric network.
5 ． Low commercial power input voltage: Adopt independent quick detection
technique, even at the lower limit 140V of commercial power, the attery
remains off discharge, thus all energy output are taken from electric
network, ensuring the attery in the state with 100% energy storage,
while at the same time decreasing the attery discharge times and
prolonging its life.
1.4 Precautions
A ide y the following general safety precaution during operation or
maintenance.
1 ． Please don't remove the cover. This system can only e maintained or
repaired y professional maintenance personnel.

2 ． Protective ground terminals should e connected to earth end for sure.
3 ． High creepage danger! Connect to the ground efore connecting UPS.
4 ． Install this UPS indoors with oth temperature and humidity under
control and without dust.
5 ． The electric power of this UPS has multiple sources. Before maintaining,
cut the alternating current, exterior attery or interior attery's air switch
to isolate the input energy.
6 ． Even if the AC power supply has een cut off, the danger from attery's
high voltage inside the UPS still exists.
7 ． If attery circuit has not een isolated from AC input, dangerous voltage
may possi ly exists etween attery terminal and ground terminal.
8 ． High voltage endangering personal safety exists in the storage attery
of this UPS. Please pay attention to insulation during installation and
use.
9 ． Improper handling of acidic attery leads to leakage risk of chemistry
dangerous su stance and corrosive liquid.
10 ． Dripping condensation should e happen if machine was operated under
low-temperature environment. So please install and use machine when
machine was full-dry, or there will has dangerous of electric shock.
Warning: Input and output voltage of this equipment is dangerous high voltage,
which can endanger personal life or safety. Please read carefully this
Manual during installation, operation and efore use. Pay attention to
various caution nameplates and caution statements. Professional
maintenance personnel without proper authorization are not allowed to
remove off the case cover of this equipment.

2.2 Basic Principles
When commercial power is normal, (3kVA) UPS input, through PFC,
increases the voltage to ±370V sta ilized DC voltage, which supplies DC/AC
inverter and transmits sta le 220VAC, while at the same time completing the
charging of the attery. When commercial power is a normal, the attery
increases the voltage through DC/DC to ± 390V DC voltage and supplies
DC/AC inverter.
UPS principle lock diagram is shown in Fig. 2-4. DC/AC inverter adopts
half- ridge structure, while DC/DC voltage increase adopts push-pull or
BOOST circuit. PFC is active power-factor correction circuit controlled y
UC3854, while CHARGER is complete isolation type charger.

3.3 Installation of UPS
Because the main unit size of (3kVA) standard time-delay model and
long time-delay model is small, the UPS can e placed on the flat surface
directly without other fixing or installation. For convenient operation,
maintenance and heat emission of the equipment, there shall e at least
30cm~50cm room space reserved around the machine frame and 50cm a ove
the upper machine frame. The vent fan shall e installed eside the attery.
Keep good interior ventilation. The service life of the attery is the longest
when the attery is used under normal temperature(20 ℃ ). Recommend to
install air-conditioning equipment in equipment rooms with allowed conditions.
Refer to Fig. 3-1 for the precautions of UPS installation and use.

-11-
Fig. 3-1 Precautions of UPS Installation and Use
1 ． Place UPS on flat floor (avoid o lique and ragged floor).
2 ． Keep good ventilation, the distance of the ack and side to the wall should
e a ove 30cm~50cm, to facilitate heat emission.
3 ． Avoid placing it in the location with sunshine, rain and dampness.
4 ． Never place it in the location with corrosive air.
5 ． Do not place articles on or around the UPS, to prevent the vent hole from
eing locked. No person is allowed to sit on it.
3.4 Selection of Cable
3.4.1 Selection of Input Air Switc
Before the input coil in of the equipment, install an air switch or a distri ution
ox compliant with the power and capa ility of the equipment, to isolate it with
commercial power. Consider especially the charge power and the current
shock, the input air switch can e higher than 1.5-2 times most current of UPS
input, which is without leakage current protection in order to avoid error action.
The distri ution ox should e etter to e manufactured y professional
company. Please refer to Ta le 3-2.
