CAUTION !
☆ Hazardous voltage exits inside the UPS (includes the connection
terminals), cable connection and maintenance should be done by
professional or qualified personnel.
☆ The UPS has its own internal battery source (battery). The output
terminals may be live even when the UPS is not connected to the
AC supply.
☆ DC capacitors are employed in this unit, hazardous voltage still
exists even when the unit is not energized. Do not touch any part
of the UPS inside.
WARNING !
☆ Be sure to operate the UPS within the rated power of the UPS.
☆ Prevent direct exposure to direct sunlight rain or contaminating
environment.
☆ Only qualified technicians should replace the batteries. Since
batteries have high short-circuit current capacity. Mistakes in
connection or disconnection can cause severe burns or death to
servicing personnel.
1. SYSTEM OVERVIEW
1.1. Construction of the UPS
General Topology:
The UPS system is composed of input breakers, input filter & protection network,
rectifier, battery bank, inverter, static switch, bypass breaker, isolation transformer
and output filter. The basic topology is shown in the diagram above. Under normal
AC mode, energy from the AC source is converted to DC power and supply to the
inverter and charge the battery to its full capacity all the time, ready to support the
output load in case of AC source failure.
Perhaps one may doubt if it is worthwhile to buy a UPS. But when you use a
calculator to add up the direct and indirect loss caused by AC failure, you will
immediately find that the money you save in 2 or 3 times of AC failure can already
compensate the cost of a UPS. Besides, the life expectancy of a UPS is at least 5 to
8 years, you may already get back the expense on the UPS within one year.
Although the principle and operation of a UPS seems simple and straightforward,
the requirement for a reliable and intelligent UPS makes the design and
manufacturing of a high power UPS requires advanced technology, intelligence,
experience and the most important, be considerate to the user. Therefore we spend
years and huge investment in developing the most rugged, intelligent and reliable
UPS for the market, safe and convenient UPS for the user.
1-1
Besides, the knowledge of choosing the best and most suitable UPS can be easy or
can be difficult, it depends on whether you know the key points or not. The most
obvious specification is the power, it depends on how large is your load. Usually, an
allowance of 50% more power must be added to the current power you needed, both
for tolerance and future expansion. Of course you can add more than 50% if you
expect a larger increase of load in the future.
Another important point is the reliability, the prime aim of a UPS is to protect your
load, and therefore the UPS should be much more reliable than the AC source.
Those unfortunate UPS users who bought a unreliable UPS may suffer the
problem of frequent break down of the UPS, even more frequent than AC failure,
the cost of repairing is more the cost of the unit itself.
The last point is to choose an honest and experienced suppler who can help you
to choose the correct UPS, react promptly in case of UPS problem. Then, you can
save your money as well as buy a correct, suitable, and reliable UPS that is the
same as buy insurance to your load.
Generally, there are four different modes of operation, the NORMAL OPERATION
MODE, the BACK-UP (BATTERY) MODE, the RESERVE MODE and the
MAINTENANCE BYPASS MODE. They are explained as below.
Normal Operation Mode:
The rectifier converts the AC input to DC power to supply the inverter and charge the
battery simultaneously. All the fluctuations, surges and spikes of the AC input is
removed during AC to DC conversion, therefore the AC supplied by the inverter is
clean and stable.
1-2
Back-up Mode:
Since the battery is connected directly to the DC bus, when the AC failure, the
battery change immediately from receiver to donor, supply energy to the inverter
instead of receiving energy from the rectifier. The output AC is not interrupted.
Therefore, the load connected to the output is protected.
Reserve Mode:
When the inverter is in abnormal conditions, such as over temperature, short circuit,
abnormal output voltage or overloaded for a period exceed the inverter’s limit, the
inverter will automatically shutdown, in order to protect itself from damage. If the
utility power is normal, the static switch shall transfer the load to the reserve source
without interruption of AC output.
1-3
Maintenance Bypass Mode:
In case of UPS maintenance or battery replacement, and the load cannot be
interrupted, the user can turn off the inverter, close the bypass breaker and then
open the rectifier and reserve breakers. The AC output will not be interrupted during
manual bypass transfer procedure. Therefore maintenance bypass switch keeps
continuously power supply to the load. Electricity will not exist in UPS except the
output transformer, thus ensure the safety of service personnel.
Generally, the UPS is expected to run 24 Hours a day in normal operation mode
once it is installed, except when the utility power is fail, under overload condition,
or during maintenance.
The normal operation with battery connected can provide a clean, stable, free from
any spikes and surges, regulated and uninterruptible power to the load. Therefore,
the UPS and be regarded as a perfect AC power source except the back-up time
under mains failure is limited by the capacity of battery connected.
1-4
1.2. Features and Advantages
(a) Reliable input protection: Circuit breakers is put in each individual input
loop to ensure power can continue through the other loop in case of breaker trip
caused abnormal condition in either rectifier or load.
(b) Input surge protection: MOV (surge protector) is added at the input, provide
sufficient protection to both UPS and the load from any lightning or surge
caused by neighboring large loads.
(c) EMI suppression: EMI filter is added to meet the international EMC limits,
therefore, very low noise is emitted and never interfere other equipment
connected to the same AC source.
(d) Ruggedness: The rectifier employ phase control technology to regulate the
DC bus voltage, so it can charge the battery directly, it is the most efficient
method to charge the battery. Besides, the component used is SCR, the
component get merits by its ruggedness under poor condition. Also, big inductor
is added at the input to avoid deforming the AC source waveform.
(e) High frequency design: The inverter uses high frequency, high efficiency
IGBT, PWM method to convert the DC power to AC power. Therefore, number
of components is fewer, in return, reliability is improved, size and weight of
UPS is reduced, then the transportation cost is cheaper, performance improved
and the acoustic noise is eliminated too.
(f) True Galvanic isolation: An isolated transformer is put at the output, can
solve the problem of poor input grounding and can accept a different ground
between input and output, can avoid the annoying problem of ground leakage
current and can be tied to any potential provided on site. The AC output is
isolated under every mode of operation. Besides, the user gets the bonus of
attenuation of common mode noise from the output isolation transformer.
1-5
(g) P&P Modular design: The power circuit is separated into several modules
plugged into slots in the UPS, which is easy to pull out, permit quick
maintenance and easier trouble shooting. Therefore, it can be regarded as plug
and play modules.
(h) Cold start function: the UPS can be started without AC source, that is, can
be started with battery only, because current limit circuitry is added. It can
prevent the problem of many UPS that the big inrush current blow the battery
fuse and hurts the DC capacitors when battery is connected to empty DC bus
(before the DC bus is energized).
(i) Multi-CPU design: Several CPUs are employed in the control circuit, critical
functions are designed to parallel redundancy to improve reliability. Therefore,
in case of one CPU fails the other CPUs keep on their duty and the output AC
will not be affected.
(j) Defense to mis-operation: The UPS is designed with breaker on/off sensor,
power supply sensor etc. Therefore any operational mistake made by the user
causes no harm to the UPS.
(k) Wide input range: The UPS is designed to accept extra wide input range, so
that it can work comfortable under poor AC source. Also, all the input
components used are especially selected to handle extreme high voltage and
high current.
(l) Tolerate harsh environment: Each component of the UPS is chosen with
larger safe margin to accept extreme environment, such as temperature, humidity,
attitude, shock or contamination.
(m) Intelligent charger: The UPS will automatically recharge (boost charge) the
battery every time after the battery is consumed to a voltage 2V/Cell, so that the
battery can be recovered to the full capacity as soon as possible to be ready for
the next back-up. Besides, in order to keep the battery in the best condition, the
UPS will boost charge the battery for several hours (selectable) automatically
every month. To avoid over charging the battery, Boost charge will stop when
the ambient temperature is over 35 ℃(95℉).
1-6
(n) Intelligent battery test: Battery is tested after every boost charge of battery
(either initiated by battery discharge or by one month has elapsed) without
stopping the rectifier to prevent the risk of output AC failure in case of battery
bad. And can inform the user the battery condition, so that the user can take
action before the capacity of the battery is needed.
(o) Huge charging power: The charge power is selectable (Lo/Me/Hi) according
to Ah of the battery, and can charge up battery of more than 8Hrs back-up time
without adding extra charger.
(p) MTBF of fans is extended: Fans will slow down under light load, so that
the life expectancy of the fans are longer than it is specified.
(q) Redundant power supply: An extra power supply is connected redundantly
to supply power of the static switch, so that, there will be AC output no matter
what happen to the UPS.
(r) Intelligent interface: One remote control panel (or one PC) can monitor up to
99 UPS, all of them can be remotely switched on or off, and when any one of
them encounters emergent condition, it will warn the user immediately. All the
UPS status, data or commands are transmitted to external modules through 4
RS-485 ports (for long distance communication under harsh environment).
(s) Emergent stop is available: In case of hazard, for example electric shock,
fire or earthquake, the UPS can be shutdown (will have no AC at the output)
either through a switch (can be added upon request) or through smoke detector
signal (can be added upon request) to prevent further injuries or destruction.

1.3. Rectifier
The main function of a rectifier is to convert the AC input to DC power, supply it to
the inverter; the inverter then converts the DC power to AC power to the load. Our
UPS use the DC power to charge the battery as well, which is the most efficient way
of charging.

6-PULS E FULL CONTROL RECTIFIER
The rectifier of f r o m 20KVA to 80KVA UPS uses 6-pulse full controlled rectifier.
An inductor is added before the rectifier to improve the power factor, smooth the
current waveform and eliminate the harmonic current as well. The control circuit
regulates the DC bus within 1%. Soft walk-in circuitry (approximately 20sec.) and
current limit circuitry is used to prevent over current or instantaneous surge current.
Extra under-voltage and over-voltage protections are added to improve reliability and
to shutdown the rectifier in case of abnormal conditions. The DC bus is adjustable to
fit different types of battery. The power component use in rectifier is especially
selected to handle extreme high voltage and high current. The rectifier is designed to
operate under wide range of AC input, from 177 to 300VAC, to fit the poor power
conditions in some area.

12-PULSE FULL CONTROL RECTIFIER
In order to further improve the power factor and reduce harmonic current drawn by
the rectifier, our UPS from 100KVA and above use the 12-pulse full controlled
rectifier. The total current harmonic current can be reduced to around 15%, and
power factor is improved to over 0.8. A phase shift transformer is added to achieve
the performance. The input inductor is retained too to obtain the best result. Although
the cost is higher, it is most reliable and rugged topology. Users need not to increase
the input breaker and cable, input KVA and harmonic current drawn is minimized to
fulfill the worldwide energy saving requirements.
The harmonic current can be further lowered by adding harmonic filters (install upon
request). The total harmonic current will be around 9%.
Another alternative method to reduce the harmonic current (especially for very large
KVA UPS) is to employ 18-pulse full controlled rectifier. The total harmonic current
will be around 7%.
1.4. Inverter

IGBT INVERTER

The inverter is composed of IGBT, inductor, capacitor, snubber, control circuitry and
protection circuitry. It can convert the DC power from the DC bus to AC power
supply to the output load. Our UPS use IGBT technology which can switched to
frequency beyond audible range, therefore no audible noise.
Our UPS use voltage regulation circuitry to limit the voltage variation within 1%.
Also special compensation circuitry is added to eliminate the output distortion. Every
component is oversized to accept the wide DC input range (from 285 to 420VDC), so
that the output waveform remains sinusoidal throughout the range. With the aid of
dynamic feedback loop the inverter will keep a sine waveform even under non-linear
load.
We use independent inverter for each phase. Although it is more expensive, each
inverter has its independent feedback, so that the voltage is unaffected when load is
added to the adjacent phase, that is excellent voltage regulation under 100%
unbalanced load.
The IGBT is operated in its optimal condition to obtain best efficiency, so as to
minimize the electricity cost of the user.
Usually, the most frequent failure of UPS happens at the inverter, therefore we added
redundant protection circuitry to protect the inverter, strong snubber is added to
suppress the spikes and noise, use over sized and high quality components, add
semi-conductor fuse and good ventilation etc. Every step aims at a rugged, reliable
and high efficient inverter. At the same time, the inverter can sustain overload and
high peak current drawn by the load. And the MTBF must be long than one expects.

The static switch is composed of two pairs of back-to-back connected SCR. It can
transfer the load from reserve to inverter or from inverter to reserve without dead
time at the output. Therefore, it is a very important portion of a UPS.
Detection circuitry is added to the control circuit to achieve zero dead time transfer.
Extra detection logic is employ to control when should the static switch transfer. For
example, when output is short circuited under normal mode operation, the UPS
detect the short circuit and stop the inverter after a period which the inverter can
endure, then the static switch will not transfer to reserve to prevent tripping and
hurting the reserve breaker. But in case of overload, the UPS will stop the inverter
after a period the inverter can endue, and then transfer the load to reserve because the
overload capability of the static switch is higher than the inverter.
Also the transfer action is determined according to the reserve-input voltage and
frequency to protect the load from supplying incorrect power to the load. At last,
there is a double check by the CPU whether the transfer is successful or not.
1.6. Maintenance Bypass Switch
Unlike other UPS, the maintenance bypass switch is already installed inside the UPS
for convenience. It should be opened under normal operation, and only closed during
maintenance. For the sake of maintenance personnel’s safety, all power supply inside
the UPS should be disconnected before touch any parts inside the UPS; therefore, the
maintenance bypass switch is a necessity to maintain AC power at the output and can
keep safe at the same time. If the bypass breaker is closed under normal operation,
the inverter will stop and the load will be automatically transferred to reserve to
prevent the inverter connect directly to the AC source. Of course, you cannot switch
on the inverter as long as the maintenance bypass breaker is closed.
The operation of the maintenance bypass breaker is that, switch off the inverter first
then the static switch will automatically transfer the load to reserve without dead
time. Then now you can close the maintenance bypass breaker now, and then open
the reserve breaker, so that the load can get AC from the output without interruption.

The front panel is located at the front of the PCB holder. It gathers the real time
information of the UPS and shows them clearly to the user. It also provides switches
for controlling and setting the UPS. So, through this panel, the UPS can be not only a
stand alone machine supplying the load but closely related to the user. Each part of
the panel is explained below.
A: LCD display: Real time status, data or historical events is displayed on the LCD.
The UPS parameters, real time clock, inverter, buzzer also can be set through this
LCD. The LCD is back lighted by LEDs for purpose of a sharp display, but in
order to lengthen the LED’s life time, the LED will be automatically shut off 3
minute after no key is activated, will light up again when one of the
up/down/enter key is pushed.
B: Status LEDs: 24 LEDs representing all the important information of the UPS
provide most update information to the user. Therefore these LEDs are especially
important when abnormal conditions happen. The 24 information are as below:
INVERTER ON – inverter is running.
INVERTER SS – inverter static switch conducts while the reserve static
switch is opened.
SHORT CIRCUIT – UPS output is in short circuit state.
FUSE/OVER TEMP SD – inverter shutdown due to either fuse broken or
temperature too high.
INVERTER FAIL SHUTDOWN – inverter shutdown due to inverter output
voltage too low.
BYPASS ON SHUTDOWN – inverter shutdown due bypass breaker is closed
when the inverter is running.
HIGH DC SHUTDOWN – inverter shutdown due to DC bus too high when
the inverter is running.
OVERLOAD SHUTDOWN – inverter shutdown due overload the inverter
for a period over the inverter can endue, will restart after 7 seconds.
70% LOAD – load connected to the output is over 70% of the UPS rating.
110% LOAD – load connected to the output is over 110% of the UPS rating.
125% LOAD – load connected to the output is over 125% of the UPS rating.
150% LOAD – load connected to the output is over 150% of the UPS rating.
1-20
RESERVE AC FAIL – reserve AC magnitude is out of range.
RESERVE FREQ FAIL – reserve frequency is out of range.
BATTERY LOW – DC bus (or battery) is lower than 320VDC, low battery
shutdown is approaching.
BATTERY LOW SHUTDOWN – inverter shutdown due to DC bus (or
battery) is lower than 295VDC (lower than the acceptable DC voltage of
the inverter.
RECT AC FAIL – rectifier AC magnitude is out of range.
ROTATION ERROR – rectifier AC phase rotation is incorrect.
RECTIFIER SHUTDOWN – rectifier shutdown due to DC bus too high
(over 445VDC), will automatically restart 30 seconds after abnormal
situation has been cleared.
HIGH DC – DC voltage over 430VDC and the bus voltage will be limited at
this voltage.
BOOST CHARGE – the battery is being boost charged by the rectifier.
BATTERY TEST – battery is being tested.
EMERGENT STOP –inverter shutdown due to emergent stop switch is
pushed.
DATA LINE – blinks when data is transmitted to or received from the
communication port.
C: Warning LEDs: When abnormal condition happens, these LEDs will lit to warn
the user according to the cause of the faulty condition. Therefore all these LEDs
should be extinguished under normal condition. These LEDs are as below:
RECT AC FAIL – rectifier AC input is abnormal either due to AC magnitude
out of the range or phase rotation error, rectifier shutdown.
RESERVE FAIL – reserve AC input is abnormal either due to AC magnitude
out of range or frequency out of range.
FUSE/TEMP – either inverter fuse is blown or over temperature.
OVERLOAD – output is overloaded by over 110%, 125% or 150%.
HIGH DC – the LED will lit as long as the DC voltage is over 430VDC.
1-21
BAT LOW – the LED will lit as long as the DC voltage is lower than
320VDC.
BAT LOW STOP – the LED will lit as long as the DC voltage is lower than
295VDC, inverter on is prohibited.
FAULT – the inverter is shutdown due to abnormal conditions such as
overload, short circuit, high DC, fuse over temperature, bypass breaker on
or emergent stop.
Since these LEDs are located behind the transparent window, the user can see
them clearly without opening the door.
D: Buzzer outlet: The buzzer is located inside the PCB holder; therefore, a hole is
opened to let the beep sound can be heard outside. Usually, the user should not be
expected to watch the UPS all the time, therefore when abnormal conditions
happen audible sound should be emitted to warn the user come over to check
what happens to the UPS. The buzzer will beep under either one of the following
conditions:
INVERTER IS OVERLOADED>110%, beep once / 3 seconds
>125%, beep once / second
>150%, beep twice / second
BACK- UP
>320VDC, beep once / 3 seconds
<320VDC, beep twice / second
<295VDC, no beeping
INVERTER IS SHORT CIRCUITED - beep continuously
FUSE BROKEN - beep continuously
HEAT SINK OVER TEMPERATURE - beep continuously
HIGH DC SHUTDOWN - beep continuously
BYPASS ON STOP - beep continuously
1-22
EMERGENT STOP - beep continuously
The buzzer will also beep once every time the inverter is switched on or off to
acknowledge the user his key is valid and accepted.
E. Bypass LED: This LED will lit when the maintenance bypass breaker is closed.
When the maintenance bypass breaker is closed, the inverter cannot be switched
on and will stop immediately even when inverter is already running.
F. Reserve LED: This LED will lit when the reserve breaker is closed, and there is
AC power supply present at the reserve terminal.
G. Rectifier LED: This LED will lit when the rectifier is operating normally, it
means the rectifier Mains is within the range specified, the rotation sequence of
three phases are correct, rectifier breaker is closed and no high DC voltage in the
bus.
H. Back-up LED: This LED will lit when the UPS is in back-up mode. This is also
as the indicator for battery test result. If the battery test do not pass, this LED will
flash even the UPS is not in back-up mode to prompt the user to change the
battery.
I. Inverter LED: This LED will lit when the inverter is switched on, therefore this
LED indicates whether the inverter is running or not.
J. Inverter SS LED: This LED will lit when the inverter static switch is turned on
and the reserve static switch is turned off. That is, the load is supplied from the
inverter. Usually this LED will lit 7sec. after the inverter is switched on.
K. Reserve SS LED: This LED will lit when the reserve static switch is turned on
and the inverter static switch is turned off. That is, the load is supplied from the
reserve. Since the reserve static switch and inverter static switch will never both
turn on simultaneously, the Inverter SS LED and the Reserve SS LED should
never both lit simultaneously.
L. Output LED: This LED will lit when there is AC power present at the output
terminal. This is an important indication to the user that whether AC is available
at the output or not.

3. INSTALLATION
3.1. Site & Environment Consideration
The main function of the UPS is to provide an safe, clean independent electrical
supply to the load so that it is free from any random variations, disturbances or
interruptions of the utility Mains, provide a constant power supply which is
perfectly regulated in both voltage and frequency. And when the Mains is not
available, the UPS can provide optimal back-up time depends on the battery bank
capacity connected to it.
Usually the life expectancy of the UPS is 5 to 10 years (battery is not included,
because life expectancy of battery depend on the type of battery, the temperature
and humidity of the environment it is installed and the type of charger is applied to
the battery). Therefore optimal life expectancy of the UPS can be achieved by
careful consideration of the site and environment.
The following precautions and recommendations should be checked in considering
the site and environment of the UPS:
(a) The UPS should be located on place with adequate ventilation (refer to the
specification of the heat dissipation of the UPS). If the UPS is installed indoors,
care must be taken in insuring the evacuation of heat from the closed room.
(b) Adequate space (at least 1M) should be allowed to open the door without
obscured by other objects for operation or maintenance. Adequate space (at least
1M) should be allowed at the top of the UPS, because heat dissipation is
ventilated through the top openings (ventilation booth is available upon request).
(c) Do not put any objects on the top of the UPS to obscure the ventilation. Do
not locate the UPS near to any heat source, or machinery, which produce
metallic coil dust or powder, or facility that will produce corrosive substances or
vapor.
(d) Do not locate the UPS below the shower of fire extinguishing system
(abnormal conditions of the UPS should be protected by cutoff the power
supply).
3-1
(e) It is necessary to guarantee the temperature and humidity values of the site
into which the UPS will be installed should be within the range allowed by the
specification. The UPS is capable of continuous normal operation within a
temperature range of 0℃(32℉) to 40℃(104℉). For optimal performance and
reliability to prolong UPS’s lifetime, it is recommended to keep the environment
temperature below 25℃, and humidity below 80%.
(f) If the UPS is installed outdoor, avoid direct exposure of the UPS to the
sunlight and rain. Avoid direct confrontation with sand, dust or wind.
(g) The floor loading capacity should be big enough to endure the weight of the
UPS. Four tough right angled steel foot stands are attached with the UPS, please
insert the corresponding screw nut (dia.1/2”) into the floor for securing the UPS
on the floor when it is locate on territory where earthquake is expected or
moving vehicle, or tanker etc. Dimensions of the 1/2” nut on the to secure the
UPS are shown below.
3-2
(h) Walls, ceilings, floors or anything near to the UPS should be preferably
constructed of non-combustible materials. The portable fire extinguisher should
be accessible nearby in case of hazard.
(i) Avoid accumulating litter or trash of any sort in or around the UPS system.
The floor area surrounding the UPS should be kept clean so that metallic powder
and filings are not sucked into the unit thus causing a short circuit and damage
to the system.
(j) Access to the UPS room should be limited to a minimum number of operation
and maintenance personnel only. The doors should be kept locked and the keys
should be confined to authorized personnel only.
(k) Personnel who operate or maintain the UPS system should be proficient in
normal and emergency operational procedures. New personnel should be
trained and qualified prior to operate the equipment.
(l) Although the UPS has past the international EMC tests, it is not
recommended to install the UPS near to any equipment that is susceptible to
electro-magnetic interference, such as computer system, monitors, radio etc.
(m) It preferably to place the UPS near to the source than near to the load.
3-3
3.2. Unpacking
Carefully take off all the packaging material of the UPS, then carefully locate the
UPS onto site which has selected with all the points in section 3.1 kept in mind.
The UPS had past the production testing and QC checking all the electrical and
mechanical characteristics in detail prior to shipment from the factory, therefore the
UPS should be in proper conditions upon receipt. Once receive the UPS, first check
visually the outlook and mechanical structure if any physical damage was made
during transportation.
Then check if all the accessories/options (match with your purchase order) have
been attached.
- DOOR KEY
- THIS INSTRUCTION MANUAL
- BATTERY FUSE (FOR BATTERY CABINET ONLY)
- SPARE SCREWS FOR COVER PLATE
- SPARE SCREWS FOR CONNECTION TERMINALS etc.
Lastly, check if the specification of the UPS identical to the specification you order.
The key items in the specification you must check are:
- RATED POWER OF THE UPS,
- INPUT VOLTAGE & FREQUENCY
- OUTPUT VOLTAGE & FREQUENCY
- NO. OF OUTPUT PHASES (1Φ OR 3Φ)
- BATTERY VOLTAGE OR CELL NO.
Check also the necessary documentation that is attached:
- GUARANTEE CARD
- AGENT/SERVICE CENTER INFORMATION
3-4
3.3. Cable Selection
The following tables list all the information between KVA of the UPS and the size
and rating of the cables. Inadequate cable size or over sized breaker will incur risk
of fire or damage of insulation. Therefore, please look up the following tables to
determine the input circuit breaker rating and the size of cable for input, output and
battery connections. These data are for reference; final decision should be made in
accordance with the local electrical regulations.

4. OPERATIONS
After all cables have been connected, the UPS is ready to operate once power
source is available at the input terminal. Before turn on any switch or breaker,
check once again the following points listed below:
(a) Check the input voltage if it conforms with the UPS’s rated input
voltage.
(b) Check the input frequency if it conforms with the UPS’s rated input
frequency.
(c) Check if all load at the output is switched off.
(d) All breakers and the battery dis-connector are opened.
(e) If there is anything not belongs to the UPS exits inside the UPS.
4.1. Switch on Procedure
If you want to start the UPS from completely shutoff to normal operation, you can
follow the steps below to turn on the UPS. (But this procedure is for standard
system, 380/220V 3 phases 4 wires Input, 10~160KVA. For special specification
and those above 160KVA, please refer to the brief instruction label stuck in front
of the PCB holder.)
(a) Close the reserve breaker – The reserve and output LED on the mimic will
lit up, indicating the reserve static switch loop is energized,
therefore the output has power now. The power supply in the UPS
also established. The fans will rotate too.
(b) Close the rectifier breaker - The rectifier will be automatically started if the
power source connected is correct. The DC voltage will slowly
rise up (15 – 30 sec.) until the designated voltage is reached, and
will keep the value anyhow. Now, the DC is already ready for the
inverter.
(c) Close the battery breaker - A fuse holder is employed the battery to the DC
bus for safety purpose. Now the battery will take over to supply
the DC bus if rectifier mains fail.

(d) Push inverter on switch – To on the inverter, the inverter on switch and the
control switch must be pressed simultaneously. The inverter will
start working and inverter output will be established in 4 sec. The
load will be automatically transferred to the inverter 3 sec. later.
Now the UPS is in normal operation now.
(e) Check if the mimic LED is correct, as shown in the figure. All warning
LEDs on the right hand side is off, two LEDs: ‘INVERTER ON’
and ‘INVERTER SS’ on the left hand side should lit. If the load is
over 70%, the ‘70% LOAD’ LED will also lit.
4.2. Shutdown Procedure
If you want to shutdown the UPS completely (no power at output or inside),
please follow the steps below. (But this procedure is for standard system,
380/220V 3 phases 4 wires Input, 10~160KVA. For special specification and those
above 160KVA, please refer to the brief instruction label stuck in front of the PCB
holder.)
(a) Switch off the inverter – The inverter can be switched off by pressing the
inverter off switch and the control switch simultaneously. And the
load will be automatically transferred to reserve without
interruption.
4-2
(b) Open the battery breaker – If you want to shutdown all the power of the
UPS, continue to open the battery breaker. Now the DC bus is
only supported by the rectifier.
(c) Open the rectifier breaker – Open the rectifier breaker will then further
take the power source away from the DC bus; therefore the DC
bus will start to drop slowly. After 5 min., the DC bus will drop to
a safe level (let say 20VDC).
(d) Open the reserve breaker – Before opening the reserve breaker, there is
power exists at the output, but after opening the reserve breaker,
the output (or load) will no longer have power supply now.
Therefore, before opening the reserve breaker must make sure
there is no critical load connected to the output.
(e) At last all power has been cut off now, there should none of the LED or
LCD lit. The UPS now is completely shut off.
4.3. From Inverter to Bypass Procedure
If you want to stop the UPS for maintenance and do not stop the power supply
from the load, you can follow the steps below to turn the UPS to maintenance
bypass mode without interrupting the output power supply. (But this procedure is
for standard system, 380/220V 3 phases 4 wires Input, 10~160KVA. For special
specification and those above 160KVA, please refer to the brief instruction label
stuck in front of the PCB holder.)
(a) Switch off the inverter – The inverter can be switched of by pressing the
inverter off switch and the control switch simultaneously. And the
load will be automatically transferred to reserve without
interruption.
4-3
(b) Open the battery breaker – You have to shutdown the power inside the UPS;
therefore, continue to open the battery breaker.
(c) Open the rectifier breaker – Open the rectifier breaker will then further
take the power source away from the DC bus; therefore, the DC
bus will start to drop slowly. After 5 min., the DC bus will drop to
a safe level (let say 20VDC).
(d) Close the bypass breaker – Now the reserve breaker and reserve static
switch is still conducting, therefore when maintenance bypass
breaker is closed, power will flow through the bypass loop instead
of the reserve loop because the impedance of bypass loop is lower.
(e) Open the reserve breaker – You can now open the reserve breaker to free
the UPS from any power supply.
4.4. From Bypass to Inverter Procedure
If the UPS is in maintenance bypass mode, and you want to turn the UPS to
normal mode without interrupting the output AC, please follow the steps below.
(But this procedure is for standard system, 380/220V 3 phases 4 wires Input,
10~160KVA. For special specification and those above 160KVA, please refer to
the brief instruction label stuck in front of the PCB holder.)
(a) Close the reserve breaker – The reserve and output LED on the mimic will
lit up, indicating the reserve static switch loop is energized,
therefore the output has power now. The power supply in the UPS
also established. The fans will rotate too.
(b) Open the bypass breaker – The inverter cannot be switched on with the
maintenance bypass breaker is closed (because the CPU will
sense the breaker and prevent the inverter to connect directly to
AC source). And the reserve breaker has already closed, therefore
power goes through the reserve loop if bypass breaker is open, AC
at output will not be interrupted.
4-4
(c) Close the rectifier breaker - The rectifier will be automatically started if the
power source connected is correct. The DC voltage will slowly
rise up (15 – 30sec.) until the designated voltage is reached, and
will keep the value anyhow. Now, the DC is already ready for the
inverter.
(d) Close the battery breaker - A fuse holder is employed in the battery to the
DC bus for safety purpose. Now the batteries will take-over to
supply the DC bus if rectifier mains fail.
(e) Push inverter on switch – To on the inverter, the inverter on switch and the
control switch must be pressed simultaneously. The inverter will
start working and inverter output will be established in 4 sec. The
load will be automatically transferred to the inverter 3 sec. later.
Now the UPS comes again into normal operation now.

5. LCD DISPLAY
The LCD can display information much more than LED can do. In order to make
the display sharp and readable, the LCD is back-lighted by LEDs. But since we
want to further prolong the life time of the LED, the CPU will cut off the power
of the LED 3 minutes after the last key of either UP, DOWN or ENTER is pressed.
Of course the back light will continue if the UP, DOWN or ENTER key is
consecutively being pressed. We start from the first page of the LCD. This screen
will pop out once the system power is enabled (i.e. the default screen).

6. INTERFACE CONNECTIONS
All interfaces are connected from 3R PCB. See the figure as below.
6.1. Dry Contacts
8 terminals of dry contact are provided. These terminals are normal open, when
event happens the terminal will conduct. Maximum contact rating is
16A/250VAC(16A/30VDC). They are:
INVON – Short whenever inverter is on, open when inverter is off.
OVL – Short whenever UPS is overloaded.
6-1
FAULT – Short when UPS encounter fault condition such as high dc shutdown,
short circuit, fuse/over-heat, overload shutdown, emergent stop, inverter
abnormal, bypass on shutdown, and is latched until manual reset (off
switch) or 30 sec. after fault condition removal
SS – Short when the inverter static switch is conducting, open when reserve
static switch is conducting (The two static switches will never conduct
simultaneously).
BYPASS – Short when the maintenance bypass breaker is closed; open when
the breaker is opened.
BACK-UP – Short when the inverter (running) is back-up by the battery.
BATL – Short when the inverter is consuming the battery and the battery is
about to be exhausted.
COM – This contact is the OR result of the signals described above. That is,
any other contact close, this contact will close too. The signal to be ored is
selectable through SWR2. See the figure

2 pairs of terminals CNR 16 are provided for external shutdown. 10mA is needed
for turning the internal photo-coupler on. User can use this terminal to shutdown
the UPS when emergent condition happens such as fire, short circuit etc.
6.3. DB9 Connection
Four RS-485 and one RS-232 are provided to communicate with more
sophisticated (option) modules. Generally, RS-485 is for long distance
transmission and RS-232 for short distance within 10 meters. The followings are
only some connection examples of optional modules. The connection could be
changed or re-arranged according to transmission requirement in the field.

7. OPTIONS
This chapter supplies a brief introduction to all the options that is available.
Similar products from other manufacturer will not fit into the UPS. Besides, the
installation of options need professional settings, trained personnel is required
during installation.
7.1. Battery Cabinet
The battery cabinet is designed with the same size and outlook as the UPS for
convenience of installation and same size and outlook when several cabinets of
UPS and battery are align together. Structural strength is enhanced to endure
vibrations, shocks etc. during transportation. See the figure below.
BATTERY CABINET
7-1
7.2. Emergent Stop Switch
A stop switch is available as option installed outside and nearby the UPS for
stopping the UPS output in case of emergency such as electrical shock, burning of
the load or any emergent conditions you want to stop the AC output immediately.
When the emergent stop switch button is pushed, the inverter will stop running
and the static switch remains at inverter, therefore there will be no AC supply to
the output. This shutdown condition will be latched until manual reset by pressing
the OFF (0) switch and inverter control switch (WX) simultaneously.
7.3. Remote Control Panel – UPSCAN™
The UPSCAN™ is a hand held display module with LCD (the same with the LCD
of UPS) and LED can monitor 1 – 99 UPSs with DB9 connected in series from
distance < 1000M. Please refer to UPSCAN™ specification for more detail
information.
7.4. Software for PC Monitoring – UPSCOM™
The UPSCOM™ is software installed in a PC to monitor multiple UPSs with DB9
connected in series. The connector on the UPS’s side is RS-485 (for long
distance transmission), therefore a RS-485 Ù RS-232 adapter (hardware) is
required to modify the signal. The software and hardware together is a package
called the UPSCOM™. For more detail information, please refer to UPSCOM™
specification.
7-2
7.5. Auto Dialing Module – UPSCALL™
In case of abnormal situation occur, the UPSCALLTM will automatically dial to
specified phone numbers to inform the person in charge to take prompt action.
The module, being with built-in 23A12V battery, consumes power only when in
the process of dialing so as to be operated under AC source failure. Furthermore,
with functions of multiple phone number setting and dialing, UPSCALLTM has no
need of dedicated line and can offer user a prompt and convenient way for
monitoring the UPS.
7.6. Battery Monitoring Module - DCMAN™
This is an intelligent module to keep watching each individual battery in the
battery bank by a simple and direct way. It can distinguish and repair the initially
aged battery under safe situation and therefore prolong the battery life expectancy.
One module can monitor up to 64 pieces of 12V battery. DCMAN will alarm in
case of the abnormal situation such as battery worn-out, cable abnormal
disconnection, and the battery amount monitored is less than the parameter set in
the module.

8. REDUNDANCY
Redundancy can be roughly divided in two types: serial (hot standby) redundancy
and parallel (active) redundancy. DS-C33 series adopts mainly the serial
redundancy.
8.1. Serial Redundancy
ONE TO ONE SERIAL REDUNDANCY
The serial (hot standby) redundancy consist of two UPS with one UPS’s (UPS1)
connect to the reserve/bypass input of the other UPS (UPS2). See in the above
figure.
8-1
The two UPSs are running in normal mode currently under normal conditions.
When one of them has problem, the load will still has protection from inverter
and battery. If UPS1 fail and UPS2 is running normally, the load is unaffectedly
supplied from UPS2. If UPS2 fail and UPS1 is running normally, UPS2 will
transfer the load to UPS1 and the load will continue to be protected by inverter
and battery of UPS1. If both of them are running normally, UPS2 takes up all load
and UPS1 bears no load. Therefore, UPS1 has a longer MTBF than UPS2 (can be
interchanged after a period of time), and their MTBF multiple to a large MTBF.
This type of redundancy is employed most frequently. Besides, when mains fail,
UPS2 is the first to contribute its battery to back-up the load, and when UPS2’s
battery is exhausted, the load will be transferred to UPS1, and now UPS1 start to
contribute its battery. Therefore, this topology can make full use of the battery.
The user will not feel wasting money in buy two UPS, for he get a system that has
double protection and double back-up time.
Another cheaper solution (see the figure next page) is if your load is separated,
you intended to install two UPSs with the same power; you can buy another UPS
as redundancy to two UPSs. The reason is that it is very rare that both UPSs
(UPS2 & UPS3) breakdown at the same time. Therefore, UPS1 can be a hot
standby UPS to two UPSs.
Anywhere, this topology already makes full use of its resources to contribute the
best protection and longest MTBF.
8-2
ONE TO TWO SERIAL REDUNDANCY
NOTE: It is easy and simple to connect our UPS in serial redundancy.
8-3
8.2. Parallel Redundancy
In order to provide more capacity for loads and backup time, we can use the parallel redundancy
operation. (Please refer to the following diagram.) Only 1 UPS can be connected in the parallel
redundancy operation. Parallel Control PCB has been integrated into CPU, so there is no extra
control unit needed.
