through computing the sampling signals, and meanwhile drive the IGBT module bas AC and change it into
high frequency SPWM waves. Secondly it output pure sine AC through inverter isolating transformer,
inverter filter. At the same time it adjust the output voltage and waves’ shape via the feedback of sampling
signals such as voltage, current and temperature.
4.3. Battery
Battery is consisted of the power slot (plastic crust), the cathode plate, the negative electrode, separator,
electrolyte, inter-unit bridge, terminations, safety valves and other components. It is a power and chemical
energy conversion devices. The working principle is, when AC is normal the charger will charge and the
battery will convert the power to chemical energy which will be stored in the battery; when the AC works
abnormally the battery will convert the chemical energy to power to UPS.

Static inverter switch
The UPS pattern is dual-mode transformation. When the inverter does not start it is bypass mode; after
turning on the inverter it will high-speedily switch from static bypass switch to static inverter output switch. As
static switch is electronic switch so there is no mechanical switching time.
4.5. Displaying and touching screen operation
4.5.1. Touching screen information
Touch-screen LCD monitors is our company’s latest invention of the UPS modules, using today's most
popular and intuitive graphical operation interface. Comparing with the traditional button-LCD display
modules, the touch-screen display module shows a more rich content which avoids frequent page turning. At
the same time because the user can get corresponding information by directly press the button on the
display screen. It is easy to use easy to get. Meanwhile touch-screen display module comes with real-time
clock and memory and can be recorded 256 incidents and other information, which is more humanize.

Working principle of complete machine
UPS is multi-lay protected alternating current supply equipment. When the main power is normal, firstly, to
rectify the main current and transfer it into pure direct current and filter the disturbance in main power; then
charge up the accumulator and output the main power. When the main power is abnormal, to invert the
direct current stocked in accumulator into alternating current and output it to ensure the high quality power
supply of user load. The manual maintenance bypass ensures the maintenance, examination and repair of
UPS on the condition of no power cut.
l
MCU control center
MCU high-speed operates such data as input, output, battery and environment; then control the running
and protection of rectifier, inverter and static switch to respond the external operation instruction.
l
Rectify and charge unit
Main power input examines the circuit and send the voltage, frequency and phase of main power input to
MCU for operation. When the voltage, frequency and phase of main power input are within the normal range,
MCU delivers the rectified control signal; rectified voltage slowly raised to rated voltage from 0V so as to
minus the strike on the input surge current.

As battery pack and DC(direct current) bus is operating in parallel, rectifier is charging the battery at the
same time, therefore, when battery’s voltage is lower than floating battery’s voltage, rectifier will operate in
constant current mode. At this time, MCU will calculate and control the feedback of charge current from
battery and the information of battery capacity set by user; when battery is charged into floating voltage, then
rectifier will change into constant voltage charging mode. Meanwhile, basing on the temperature of battery,
MCU will charge battery in a temperature compensation style, maintain and manage battery in a regular time
on the basis of its using situation (when battery hasn’t been charged or discharged for a very long time, MCU
will automatically transfer into an equalized charging mode in order to activate the activity of battery), thus it
will extend battery’s lifetime and reduce user’s burden of management.
l
IGBT inverter unit
When DC bus is normal, if MCU issues inverter control signal, inverter circuit will drive IGBT Inverter
Bridge by SPWM driving signal, through inverter’s isolation, voltage transformation and wave filtration,
produce out pure sine AC (altering current). Through adjusting driving signal’s pulse width, Inverter can raise
output voltage from 0V to rated degree, and control stability of output through its feedback. Meanwhile,
check voltage and current of output in order to protect inverter.
l
Automatic and manual bypass unit
Bypass circuit can directly convert input electricity into output electricity through switch circuit. If inverter is
closed or fell, MCU-controlled high-speed static switch will automatically switch into bypass electricity,
without interrupt loaded power supply.
Bypass and main power can be a same group of power supply; it also can be a different AC (altering
current).
l
Display communication unit:
Display unit is to show operational status and data of entire machine through LCD and LED, and through
RS232, RS485, dry contact signal, SNMP card, etc., realize long-distance monitor with background
software.
L series 3/3 adopt large-screen LCD (320×240) and touch-screen design, graphical manipulative interface,
tabular data display. With 256 long record of incident, L series 3/3 can provide great help to your power
supply status’s analysis and management.
POCASA-styled UPS highly integrates digital technology, improves MTBF and reliability, its independent
main control board controls the whole system’s work. Meanwhile, it is controlled by a high-speed
microprocessor, which ensures the stability of equipment and the reliability of operation.

Before installing UPS, turn off all switches. According to left part of the above plan, A, B, C, N connect
three-phase, separately to the fire wire and middle wire of main power input; A, B, C, N on bypass connect
three-phase, separately to the fire wire and middle wire of bypass input(when one power inputs, link the
main power input and bypass input together); According to right part of the above plan, A, B, C, N connect to
three-phase, separately to the fire wire and middle wire of AC output.; E is connected to the safe protecting
ground wire; +, - are connected to the anode and cathode of battery.
6.3.3. Battery connection
1.
Before connecting battery, please check manufacturers of each battery, specifications and models,
and terminal voltage to make sure whether they are in consistent (because different manufacturers’
battery internal resistances are different. When battery pack run in series, because of uneven
voltage, the whole battery pack can be damaged; meanwhile, the old and new batteries from same
manufacturers cannot be mixed as well).
2.
The input battery voltage of UPS is voltage of battery pack in series, the labeled voltage is a
standard value, and it is the summation of all batteries’ standard values in the battery pack running
in series. For example, the standard value of a single 100AH/12VDC is 12VDC rather than
measured value. The input voltage of L10K3/3 battery is 384VDC, namely, 12VDC×32=384VDC.
3.
Series and parallel connection of battery:
When the capacity of a single battery pack meet required backup time, then all the batteries should
be connected in series; or couples of series connected batteries should be connected in parallel,
the bus voltage of battery must be the same when connecting in parallel, capacity is equivalent to

When connecting in series, the first battery’s anode is connected to the second battery’s cathode, the
second battery’s anode is connected to the second battery’s cathode, and so is the other battery’s
connection.
When connecting in parallel, the battery pack’s anodes are connected together; the battery pack’s
cathodes are connected together.
Ø
Open the chassis of battery box connect according the above methods.
Ø
Install battery on the appropriate position; connect battery wire rightly according to the above
connecting methods.
Ø
Connect the cable of battery to UPS’s battery terminal board.
6.3.4. RS232 cable connections
Connect one end of DB9 signal cable which is distributed from UPS to the serial port of computer’s DB9,
connect the other end to the interface of UPS’s RS232. If the distance is too far to connect, then you can
increase the standard length of communication wire of D89, however, it should not exceeded 30 meters, or it
can not communicate normally.
6.3.5. RS485 cable connection
According to UPS’s A, B and G, use communication wires to connect the interfaces of computer's RS485
and UPS’s RS485. The longest linking distance should be less than 4,000M, or it can not communicate
normally.
6.3.6. Connection method of SNMP card
The international standard of producing twisted-pair: EIA/TIA568A and EIA/TIA568B. Both ends of plug
should follow 568 A or 568 B standard.
Network cable production:
(1) Cut: use knife-edge scissor of press line pliers to cut network cables with appropriate length.
(2) Peel: use knife-edge of press line pliers to shear cables orderly, then put wire heads on peeling blade,
make wire heads touch baffle, then slightly clench pliers and slowly rotate it, let knife rip off the protecting
rubber skin of twisted pair, peel off the skin(note: strip as long as thumb’s length).
37
PDF 文件使用 "pdfFactory Pro" 试用版本创建 www.fineprint.cn
【Tip】: The length between baffle and peeling blade of press line pliers usually is just same length as plug’s,
which can effectively avoiding peeling too long or too short. If peel too long, the network cable will look ugly,
meanwhile, it can not be stuck by plug, the connection point can easily get to loose; if peel too short,
because of the existing of protecting skin, cables become too thick to plug into the bottom of plug, which
results in plug can not contact perfectly with cable cores. Production can not be success as well.
(3) Sort: after removing outer protecting skin, you can see four pairs of twisted-pair’s eight cores, and each
pair’s color is different. Each pair of two allied core wires consists by one core wire stained with a
corresponding color and one core wire stained with white and little corresponding color. The colors of four
panchromatic core wires are: brown, orange, green and blue. Each pair is entangled with each other. When
produce network cable, these four pairs of eight thin cores should be disassembled, tidied up, straightened
and sorted in sequence according to the following wire order regulation.
Put the side with plastic spring of plug down, up the side with pin, make the end with pin towards to the
opposite direction of yourself, the end with square hole towards to yourself, simultaneously, the far left is the
first wire, the far right is the eighth wire, followed by the remaining order.

(4) Cut: straighten wires as right as possible (do not wrap), press to flat (do not overlap), tighten and tidy
up (lean against each other in one direction), and then use press line pliers to cut flush. In this way, after
inserting twisted pair into plug, each wire can well contact plug’s pin, which avoids bad connection. If the
former skin is peeled too long, then it can be cut shorter at this stage. Except outer insulation skin, the
remained part is about 14mm, which length can rightly insert each thin wire into corresponding trucking. If
this part is too long, for one hand it can increase mutual crosstalk, because allied wires ate no longer twist
together, for the other hand, owing to the plug can not pin the sheathes, cables derail from plug, which can
cause bad connection or even Interruption.
(5) Insert: use one hand’s thumb and middle finger to nip plug, the plastic shrapnel of plug faces downside,
its pin towards the opposite direction of yourself, using your forefinger to hold it. Other hand nips the rubber
skin which is outside of twisted pair, slowly inserts eight wires along RJ-45’s eight truckings with proper force
until reaching the top of trucking.
(6) Press: when all wires are in place, and all wires’ sequence is correct after thoroughly checking over
through connectors, then you can use press line pliers to make RJ-45 plug. Push one head of RJ-45, from
the side without teeth, into the trough of press line pliers, then clench pliers at full tilt(if your strength is not
enough, you can use both hands to press), press pins which are prominent outside into plug.
Network cable connection:
