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.

WA RNING !

☆ 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, inve

rte

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

dire

ct 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,

for

the requirement

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 c

ons

iderate 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.

1-2

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 lar

e 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.

1-3

Back-up Mode:

Since the battery is connected directly to the DC bus, when the AC failure, the battery change immediately instead of receiving energy from the rectifier. The

from

receiver to donor, supply energy to the inverter

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.

1-4

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.

1-5

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.

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 conv

ert 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.

1-6

(g) P&P Modular design: The power circuit is separated into several modules

plugged into slots in

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℉).

1-7

(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

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 i

s th

e most efficient way

of charging.

CAPACITOR

The rectifier of from 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

TO LOAD

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 suppress the spikes and noise, use over sized and

protect the inverter, strong snubber is added to

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 in

verter 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 for controlling and setting the UPS. So, through this

and shows

them clearly to the user. It also provides switches

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

light

by LEDs for purpose of a sharp display, but in

back order to lengthen the LED’s life time, the LED will be automatically shut off 3 minute a

fter

no key is activated, will light

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.

1-21

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.

1-22

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

1-23

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

itch 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

itch 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.

1-24

M. Up key: This is a LCD control key. It is for moving the cursor one item upward

when items are

being s

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).

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).

3-2

(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 norm

al 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.

3-3

(h) Walls, ceilings, floors or anything near to the UPS should be preferably

constructed

of non-combustibl

e 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.

3-4

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

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.

(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.

the battery breaker.

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.)

5. LCD DISPLAY

The LCD can display information much more than LED can do. In order to make the display sharp

and readab

le, 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).

The first row will display the greeting context being set by the factory or sole agent. Changing the

context of

this row is not recommended. The model no. (MODEL), serial no.(S/N), and the identification no.(ID) are displayed in the second row. While the third row will display the KVA rating, input rating and output rating of the UPS. Changing the model no. of the second row will change the rating displayed in the second row too (rating is automatically generated by CPU inside the UPS according to the MODEL no.).

WARNING: Never change the model number yourself, because some

parameters will be changed along with the model number.

5-2

Serial number is set by factory for the convenience of maintenance personnel who may need to take

down

the serial no. of the UPS he has attended. The identification no. is set only when external module connect to more than one UPS, each UPS must have a unique number to identify itself, and it should be set by installation technical personnel after installation. The YEAR/MONTH/DATE, DAY OF THE WEEK, HOUR: MINUTE and AM (PM) from the real time clock inside the UPS are displayed in the fourth row for user’s reference and stamping the date and time in the historical data when abnormal conditions happen. By pressing one of the UP, DOWN or ENTER key, the LCD will change to another screen, the MENU 1.

It is a display menu jump from MENU 1 when STATUS/WARN/FAULT is selected. The left hand side of this menu shows the real time status of the rectifier, inverter and static switch states. While the right hand side shows the warning or fault condition if any. Therefore, under normal condition, the LCD display should be exactly the same as the figure shown above. When minor abnormal condition happens it will be shown under the title < WARNING >, but will be overridden by fault message if more serious abnormal condition happens, and the title < WARNING > will change to < FAULT >. For example, short circuit happens at the output, this screen will display as follows:

＜ S T A T U S ＞＜ F A U L T ＞

7.2. Emergent Stop Switch

A stop switch is available as option installed outside and nearby the UPS for stopping the UPS output

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

(0)

the OFF

switch and inverter control switch (WX) simultaneously.

7.3. Remote Control Panel –

specification for more detail

information.

7.4. Software for PC Monitoring –

The

UPSCOM™

is software installed in a PC to monitor multiple UPSs with DB9

UPSCOM™

connected in series. The connector on the UPS’s side is RS-485 (for long

distance transmission), therefore a RS-485

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.

7.5. Auto Dialing Module – In case of abnormal situation occur, the UPSCALL

UPSCALL™

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, UPSCALL

and

need of dedicated line

can offer user a prompt and convenient way for

has no

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

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.

8-2

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. 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.
