1.3 Primary Functions and Characteristics
1．Intelligent RS232 communication function: With RS232 standard data
interface and UPS power management software, realize three
remote-control functions between 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 enables UPS to directly become the new member of network.
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 reliability 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, battery low-voltage protection, input low-voltage
protection and triple overflowing protection, etc and overcome previous
defects such as high frequency UPS' poor adaptability and weak
resistance to shock for electric network.
5．Low commercial power input voltage: Adopt independent quick detection
technique, even at the lower limit 120V of commercial power, the battery
remains off discharge, thus all energy output are taken from electric
network, ensuring the battery in the state with 100% energy storage,
while at the same time decreasing the battery discharge times and
prolonging its life.
1.4 Precautions
Abide by the following general safety precaution during operation or
maintenance.
1．Please don't remove the cover. This system can only be maintained or
repaired by professional maintenance personnel.

Rack mount Series UPS (1~3kVA) User ‘s Manual

2．Protective ground terminals should be connected to earth end for sure.
3．High leakage danger! Connect to the ground before connecting UPS.
4．Install this UPS indoors with both 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 battery or interior battery's air switch
to isolate the input energy.
6．Even if the AC power supply has been cut off, the danger from battery's
high voltage inside the UPS still exists.
7．If battery circuit has not been isolated from AC input, dangerous voltage
may possibly exists between battery terminal and ground terminal.
8．High voltage endangering personal safety exists in the storage battery
of this UPS. Please pay attention to insulation during installation and
use.
9．Improper handling of acidic battery leads to leakage risk of chemistry
dangerous substance and corrosive liquid.
10．Dripping condensation should be 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 before 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, rack mount series UPS input, through PFC,
increases the voltage to ±360V stabilized DC voltage, which supplies DC/AC
inverter and transmits stable 220V AC, while at the same time completing the
charging of the battery. When commercial power is abnormal, the battery
increases the voltage through DC/DC to ± 360V DC voltage and supplies
DC/AC inverter.
UPS principle lock diagram is shown in Fig. 2-7. DC/AC inverter adopts
half-bridge structure, while DC/DC voltage increase adopts push-pull or
BOOST circuit. PFC is active power-factor correction circuit controlled by
UC3854, while CHARGER is complete isolation type charger.

3 .Equipment Installation（删除上面一空白页）
3.1 Site and Environment Requirements
Before UPS installation, the site and environment of equipment room should
meet the essential conditions for safe and normal operation of equipment as
defined in this section. If the customer’s site conditions are not accord with the
minimum requirement of safe equipment operation, the customer should make
corresponding changes to the site conditions, and install the equipment only
after meeting the conditions of safe and normal equipment operation.
3.1.1 Site Requirements
The site conditions should accord with the essential conditions of safe and
normal equipment operation as stated in this section.
1．The equipment room must be equipped with applicable and effective fire
apparatus;
2．The commercial power, which supplies power for UPS, should be equipped
with dedicated air switch or utility socket;
3．Strictly prohibit storing dangerous things, such as inflammable things,
explosive things in the equipment room;
4．Before equipment installation, the ground wire should be prepared. The
voltage of neutral wire and ground wire of commercial power cannot
exceed 5V;
5．The civil engineering construction of the equipment room should be
completed totally, and the floor should be sclerotic. The site must be tidy
and dry without dust.
3.1.2 Environment Requirements
Ambient temperature: 0℃～+40℃;
Relative humidity: 0%RH～95%RH, no condensation;
Cooling mode: air-cooling;
Verticality: no shock with orthogonal rake not exceeding 5º.

3.2 Procedures of Dismantling Cases
When installing the equipment, the packing should be removed after carrying
the equipment to the installation site. The packing of UPS equipment and
fittings (battery, etc.) should be wooden case and carton. Check the UPS
equipment and fittings against the shipping list.
If the equipment or fittings are damaged during transportation or the equipment
and fittings are not accord with the ordering contract, make site record in time
and immediately contact the local office or distributors.
3.3 Installation of UPS
Because the main unit size of rack mount series standard time-delay model
and long time-delay model is small, the UPS can be placed on the flat surface
directly without other fixing or installation. For convenient operation,
maintenance and heat emission of the equipment, there shall be at least
30cm~50cm room space reserved around the machine frame and 50cm above
the upper machine frame. The vent fan shall be installed beside the battery.
Keep good interior ventilation. The service life of the battery is the longest
when the battery 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.
Fig. 3-1 Precautions of UPS Installation and Use

Rack mount Series UPS (1~3kVA) User ‘s Manual
-13-
1．Place UPS on flat floor (avoid oblique and ragged floor).
2．Keep good ventilation, the distance of the back and side to the wall should
be above 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
being blocked. No person is allowed to sit on it.
3.4 Selection of Cable
3.4.1 Selection of Input Air Switch
Before the input coil in of the equipment, install an air switch or a distribution
box compliant with the power and capability of the equipment, to isolate it with
commercial power. Consider especially the charge power and the current
shock, the input air switch can be higher than 1.5-2 times most current of UPS
input, which is without leakage protection in order to avoid error action. The
distribution box should be better to be manufactured by professional company.
Please refer to Table 3-1.
