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 supplied to the
inverter to charge the batteries to its full capacity all the time, ready to support the
output load in case of AC source failure.
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 one requiring advanced technology,
intelligence, experience and most important, consideration of the user interface.
Many years have been spent in designing the most rugged, intelligent and reliable
UPS for the market, and a safe and convenient UPS for the user.
Choosing the best and most suitable UPS for a given application can be easy or
difficult, depending on the client’s knowledge of key parameters. The most obvious
specification, output power, depends on the size of the load. Often, an allowance of
50% more power is added to the present load requirement, both for tolerance and
for future expansion.
1-1
Another important issue is reliability. The prime aim of a UPS is to protect your
load. Therefore, the UPS should be much more reliable than the AC source. An
unreliable UPS may suffer the problem of frequent break down, even more frequent
than AC failure, and the cost of repair may become more than the cost of the unit
itself.
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. These are explained below.
Normal Operation Mode:
The rectifier converts the AC input to DC power to supply the inverter and charge the
batteries simultaneously. All the fluctuations, surges and spikes of the AC input are
removed during AC to DC conversion. Therefore, the AC supplied by the inverter is
clean and stable.
1-2
Back-up Mode:
Since the batteries are connected directly to the DC bus, when the AC fails, the
batteries change immediately from receiver to donor, supplying 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 an abnormal condition, such as over temperature, short
circuit, abnormal output voltage or overloaded for a period exceeding the inverter’s
limit, the inverter will automatically shut down 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 where 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, the maintenance bypass switch keeps
continuously supplying power to the load. Electricity will not exist in UPS except
the output transformer, thus ensuring 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 fails, under overload conditions,
or during maintenance.
Normal operation with batteries connected provides clean, stable, regulated and
uninterrupted power to the load, free from any spikes and surges. Therefore, the
UPS can be regarded as a perfect AC power source, limited in back-up time, under
mains failure, only by the capacity of the batteries.
1-4
1.2. Features and Advantages
(a) Reliable input protection: Circuit breakers are placed in each individual
input loop to ensure power can continue through another loop in case of
breaker trip caused by an abnormal condition in either rectifier or load.
(b) Input surge protection: An MOV (surge protector) is added at the input,
providing protection to both UPS and the load from any lightning surges, or
surges caused by neighboring large loads.
(c) EMI suppression: An EMI filter is added to meet the international EMC
limits. Therefore, very low noise is emitted, and no interference is supplied to
other equipment connected to the same AC source.
(d) Ruggedness: The rectifier employs phase control technology to regulate the
DC bus voltage. This is the most efficient method to charge the batteries. The
SCR used are inherently rugged. Additionally, a large 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 methodology to convert the DC power to AC power. Therefore, the
number of components is fewer, reliability is improved, and the size and weight
of UPS is reduced, performance is improved, and acoustic noise is minimized.
(f) True Galvanic isolation: An isolation transformer is placed at the output.
This can solve the problem of poor input grounding, can allow 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. Additionally, the user gets the bonus
of attenuation of common mode noise from the output isolation transformer.
1-5
(g) Plug & Play Modular design: The power circuit is separated into several
modules plugged into slots in the UPS, which are easy to pull out, permitting
quick maintenance and easier trouble shooting.
(h) Cold start function: the UPS can be started without an AC source, that is,
can be started with battery power only. This is possible because current limit
circuitry is added, preventing the problem of large inrush current blowing the
battery fuse and damaging the DC capacitors when batteries are connected to an
empty DC bus (before the DC bus is energized).
(i) Multi-CPU design: Several CPUs are employed in the control circuit, and
critical functions are designed with parallel redundancy to improve reliability.
Therefore, in case of one CPU failure, the other CPUs keep the UPS operational,
and the output AC is not affected.
(j) Protection against misuse: 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) Accepts wide input range: The UPS is designed to accept a wide input range,
so that it can work effectively under an unstable AC source. All of the input
components used are specifically selected to handle extreme high voltage and
high current.
(l) Operating environment: Each component of the UPS is chosen with large
safety margin to accommodate extreme environments, such as temperature,
humidity, altitude, shock or contamination.
(m) Intelligent charger: The UPS will automatically recharge (boost charge) the
batteries every time the batteries are depleted to a voltage level equal to 2V/Cell.
Thus, the batteries can be restored to full capacity as soon as possible, and made
ready for the next back-up requirement. In order to keep the batteries in the
best condition, the UPS will boost charge the batteries for several hours
(selectable) automatically every month. To avoid over charging the batteries,
boost charge will stop when the ambient temperature is over 35oC (95oF).
1-6
(n) Intelligent battery test: The batteries are tested after every boost (initiated
by battery discharge or by the monthly boost charge cycle). This is done without
interrupting the operation of the rectifier, preventing the risk of output AC
failure in case of a bad battery. The user is informed of the battery condition, so
that action can be taken before the full capacity of the batteries is needed.
(o) Huge charging power: The charging power is selectable (Lo/Me/Hi)
according to Ah rating of the batteries, and can charge up battery banks
providing more than 8Hrs back-up time without adding an extra charger.
(p) MTBF of fans are extended: Fans used to cool the UPS, are designed to slow
down under light load, so that the life expectancy of the fans is extended beyond
the normal.
(q) Redundant power supply: A supplemental power supply is added to provide
redundancy for supplying power to the static switch, so that there will be AC
output no matter what happens to the UPS.
(r) Variety of accessory (options): With built-in intelligent communication
interface as well as output ports of RS-232, RS-485, and dry contacts, there are
several options are hence available such as remote control panel, 3 phases
software for PC monitoring, auto dialing module, battery monitoring module, 3
phases SNMP card, and emergent power off (EPO) switch. Please refer to the
chapter 7 of options for details.
1-7
1.3. Rectifier
The main function of a rectifier is to convert the AC input to DC power, and supply it
to the inverter. The inverter then converts the DC power to AC power for the load.
The UPS use the DC power to charge the batteries as well, which is the most
efficient method of charging.

6-PULSEFULLCONTROLRECTIFIER
UPSs in the sizes 10KVA to 100KVA use 6-pulse fully controlled rectification
(optional 12-pulse). An inductor is added before the rectifier to improve the power
factor, smooth the current waveform and eliminate the harmonic current. 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 batteries. The power component used in the rectifier is specially
selected to handle extreme high voltage and high current. The rectifier is designed to
operate under a wide range of AC input, from 177 to 300VAC, to operate under the
poor power conditions found in some areas.

In order to further improve the power factor and reduce harmonic current drawn by
the rectifier, UPS at 120KVA and above, use the 12-pulse full controlled rectifier.
The total current harmonic current can be reduced to around 15%, and power factor
improved to over 0.8. A phase shift transformer is added to achieve this performance.
The input inductor is retained also to obtain the best result. Although this results in
higher cost, the unit is much more reliable and rugged. Users do not need to increase
the input breaker and cable sizes, since input KVA and harmonic current drawn is
minimized, fulfilling the worldwide energy saving requirements.
The harmonic current can be further lowered by adding harmonic filters (factory
installation available). The total harmonic current can be reduced to approximately
9%.

IGBT INVERTER
The inverter is composed of IGBT, inductor, capacitor, snubber, control circuitry and
protection circuitry. The inverter converts the DC power from the DC bus to AC
power to supply the output load. The UPS uses IGBT technology which switches at
frequencies beyond the audible range, therefore producing no audible noise.
The UPS uses voltage regulation circuitry to limit the voltage variation within 1%.
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.
An independent inverter is used 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, producing excellent voltage regulation under 100%
unbalanced load.
The IGBT is operated in its optimal condition to obtain best efficiency, so as to
minimize the power cost of the user.
1-10
Usually, the most frequent failures of the UPS occur at the inverter. Therefore, we
have added redundant protection circuitry to protect the inverter. A strong snubber is
added to suppress the spikes and noise, oversized, high quality components are used
throughout, semi-conductor fuses are provided, and ventilation is maximized. The
result of this design is a more rugged, reliable and high efficient inverter. At the same
time, the inverter can sustain overload and high peak current drawn by the load.
Additionally, a longer MTBF is achieved.

The static switch is composed of two pairs of SCRs, connected back-to-back. The
switch can transfer the load from reserve to inverter or from inverter to reserve
without losing power 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 employed to control when the static switch should transfer.
For example, when output is short circuited, under normal mode operation, the UPS
detects the short circuit and stops the inverter. The static switch will not transfer
power to the reserve circuit, which might damage the reserve breaker. In case of an
overload, the UPS will stop the inverter after a period the inverter can endure, and
then transfer the load to the reserve circuit, since the overload capability of the static
switch is higher than the inverter.
The transfer action is determined according to the reserve-input voltage and
frequency to protect supplying incorrect power to the load. Finally, there is a double
check by the CPU as to whether the transfer is successful or not.
1-11
1.6. Maintenance Bypass Switch
Unlike other UPS, the maintenance bypass switch is already installed inside the UPS
for convenience. It should be open under normal operation, and only closed during
maintenance. For the sake of safety of maintenance personnel, all power supplies
inside the UPS should be disconnected before touching any parts inside the UPS.
Thus, the maintenance bypass switch is a necessity to maintain AC power at the
output and yet keep maintenance personnel 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 connecting directly to the
AC source. Of course, you cannot switch on the inverter as long as the maintenance
bypass breaker is closed.
To properly use the maintenance bypass breaker, switch off the inverter first. The
static switch will automatically transfer the load to reserve without dead time. Then
one can close the maintenance bypass breaker, then open the reserve breaker, so that
the load gets power from the output without interruption.

1.8. Front Panel
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. Through this panel, the UPS can be not only a
stand alone machine supplying the load, but also closely monitored by the user. Each
part of the panel is explained below.
A: LCD display: Real time status, data or historical events are displayed on the LCD.
The UPS parameters, real time clock, inverter, and buzzer also can be set through
this LCD. The LCD is back-lighted by LEDs to provide a sharp display. In order
to lengthen the LED’s life time, the LED are automatically shut off 3 minutes
after no key is activated, but will light up again when one of the up/down/enter
key is pushed.
B: Status LEDs: 24 LEDs, representing all of the important information of the UPS,
provide the most up to date information to the user. Therefore these LEDs are
especially important when abnormal conditions occur. The 24 information items
are as shown 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
over temperature condition.
INVERTER FAIL SHUTDOWN – inverter shutdown due to inverter output
voltage too low.
BYPASS ON SHUTDOWN – inverter shutdown due to bypass breaker being
closed while the inverter is running.
HIGH DC SHUTDOWN – inverter shutdown due to overly high DC bus
voltage condition while the inverter is running.
OVERLOAD SHUTDOWN – inverter shutdown due to overload of the
inverter for a period over that which the inverter can endure; will restart 7
seconds after overload removed.
70% LOAD – load connected to the output is at or over 70% of the UPS
rating.
1-21
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.
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) 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 batteries are being boost charged by the rectifier.
BATTERY TEST – batteries are being tested.
EMERGENCY STOP – inverter shutdown due to emergency stop switch
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 light 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 shown
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 –Inverter fuse is blown or over temperature condition exists.
OVERLOAD – output is overloaded by over 110%, 125% or 150%.
1-22
HIGH DC – the LED will light as long as the DC voltage is over 430VDC.
BAT LOW – the LED will light as long as the DC voltage is lower than
320VDC.
BAT LOW STOP – the LED will light as long as the DC voltage is lower than
295VDC, inverter cannot start.
FAULT – the inverter is shutdown due to abnormal conditions such as
overload, short circuit, high DC, fuse over temperature, bypass breaker on
or emergency stop.
Since these LEDs are located behind the transparent window, the user can see
them clearly without opening the door.
D: Audible (buzzer) alarm: The user should not be expected to watch the UPS all
the time. Therefore, when abnormal conditions occur, an audible sound should
be emitted to warn the user to check the status of the UPS. The alarm buzzer will
beep under any 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
EMERGENCY STOP – (emergency power off) beep continuously
The buzzer will also beep once every time the inverter is switched on or off to
acknowledge to the user that his key is valid and accepted.
1-23
E. Bypass LED: This LED will light 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 light when the reserve breaker is closed, and there is
AC power supply present at the reserve terminal.
G. Rectifier LED: This LED will light when the rectifier is operating normally,
meaning the rectifier Mains are within the range specified, the rotation sequence
of three phases is correct, the rectifier breaker is closed, and no high DC voltage
is on the bus.
H. Back-up LED: This LED will light when the UPS is in back-up mode. This is
also as the indicator for battery test result. If the battery test does not pass, this
LED will flash even if the UPS is not in back-up mode, to prompt the user to
change the batteries.
I. Inverter LED: This LED will light when the inverter is switched on, indicating
whether the inverter is running or not.
J. Inverter SS LED: This LED will light when the inverter static switch is turned on
and the reserve static switch is turned off, i.e., the load is supplied from the
inverter. Usually this LED will light 7 seconds after the inverter is switched on.
K. Reserve SS LED: This LED will light when the reserve static switch is turned on
and the inverter static switch is turned off, i.e., 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 be lit simultaneously.
L. Output LED: This LED will light when there is AC power present at the output
terminal. This is an important indication to the user at to 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 selected or for changing the number/character forward
when data or parameter of the UPS is being set.
N. Down key: This is a LCD control key. It is for moving the cursor one item
downward when items are being selected or for changing the number/ character
backward when data or parameter of the UPS is being set.
O. Enter key: This is a LCD control key. It is for changing backward to the previous
page, and also for confirming the number/character /item is selected.
P. Inverter on switch: This is an inverter control switch. When this key is pushed
with the control key simultaneously, the inverter will be switched on.
Q. Inverter control switch: This is an inverter control switch. When this key is
pushed with the inverter on key simultaneously, the inverter will be switched on.
Similarly, when this key is pushed with the inverter off key simultaneously, the
inverter will be switched off. Thus, this key is a guard for mistaken key strokes.
R. Inverter off switch: This is an inverter control switch. When this key is pushed
with the control key simultaneously, the inverter will be switched off.

3. INSTALLATION
3.1. Site & Environment Considerations
The main function of the UPS is to provide a safe, clean independent electrical
supply to the load so that it is free from any random variations, disturbances or
interruptions of the utility Mains. The UPS also provides a constant power supply
which is perfectly regulated in both voltage and frequency. And when the Mains are
not available, the UPS can provide optimal back-up time depending on the battery
bank capacity connected to it.
Usually the life expectancy of the UPS is 5 to 10 years (batteries are not included,
because life expectancy of batteries depend on the type of battery, the temperature
and humidity of the environment in which it is installed, and the type of charger that
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 in a 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 a closed room.
(b) Adequate space (at least 1M) should be allowed to open the door,
unobstructed 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.
(c) Do not put any objects on the top of the UPS that may obstruct ventilation. Do
not locate the UPS near any heat source, machinery which produce metallic dust
or powder, or any facility that will produce corrosive substances or vapor.
(d) Protect the UPS from accidental damage from fire extinguishing (sprinkler)
systems. Protect the UPS from abnormal conditions with a dedicated cutoff
from the incoming power.
3-1
(e) It is necessary to guarantee the temperature and humidity values of the site
into which the UPS will be installed. These 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, and 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 outdoors, avoid direct exposure of the UPS to the
sunlight, wind, and rain. Avoid any exposure to sand or dust.
(g) The floor loading capacity should be high enough to endure the weight of the
UPS. The UPS is mounted on four right-angled steel angles. Insert
corresponding bolts and nut2 (dia.1/2”) into the floor for securing the UPS on
the floor when it is located in an area where earthquakes is possible, or where
motion may occur, e.g. vehicle mounted. Layout dimensions, in millimeters, are
shown below.
3-2
(h) Walls, ceilings, and floors near the UPS should be preferably constructed of
non-combustible materials. A portable fire extinguisher should be accessible
nearby in case of hazard.
(i) Avoid accumulating combustible materials of any sort in or around the UPS
system. The floor area surrounding the UPS should be kept clean so that foreign
materials 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 operating the equipment.
(l) Although the UPS has passed International EMC tests, it is recommended
that the UPS not be installed near any equipment that is susceptible to
electro-magnetic interference, such as computer systems, monitors, radios, etc.
(m) It is preferable to place the UPS near to the source rather than near to the
load.
3-3
3.2. Unpacking
Carefully unpack the UPS, and then carefully locate the UPS onto the site which has
selected, with all the points in section 3.1 kept in mind.
The UPS has had detailed production and QC testing of all the electrical and
mechanical characteristics prior to shipment from the factory. Therefore, the UPS
should be in proper condition upon receipt. Once received, the UPS should be first
checked visually to determine if any physical damage has occurred during
transportation.
Then check to insure that all the accessories/options (match with your purchase
order) have been included.
- DOOR KEY
- THIS INSTRUCTION MANUAL
- BATTERY FUSE (FOR BATTERY CABINET ONLY)
- SPARE SCREWS FOR COVER PLATE
- SPARE SCREWS FOR CONNECTION TERMINALS etc.
Lastly, check to insure that the specification of the UPS is identical to the
specification of your 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.
3-4
3.3. Cable Selection
The following tables list typical information concerning the KVA of the UPS versus
the size and rating of the cables. Inadequate cable size or over sized breakers will
incur risk of fire or damage of insulation. Therefore, please use 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 decisions should be
made in accordance with the local electrical codes.

4. OPERATIONS
After all cables have been connected, and power source is available at the input
terminals, the UPS is ready to operate. Before turning on any switch or breaker,
once again check the following:
(a) Check that the input voltage conforms to the UPS’s rated input voltage.
(b) Check that the input frequency conforms with the UPS’s rated input
frequency.
(c) Check that the load at the output is switched off.
(d) Check that all breakers and the battery disconnects are opened.
(e) Check that no foreign material is inside the UPS.
4.1. Startup Procedure
To start the UPS from complete shutoff to normal operation, follow the steps
below to turn on the UPS.
(a) In case there is an extra input breaker for some special specification, please
close the input breaker first.)
(b) Close the reserve breaker – The reserve and output LED on the mimic
panel will light up, indicating the reserve static switch loop is
energized. Therefore the output has power now. The supply of
power in the UPS is established and the fans will operate.
(c) Close the rectifier breaker - The rectifier will be automatically started if the
power source connected is correct. Wait 30 sec for DC bus
voltage to rise until the warning LEDs of “BAT LOW” and “BAT
LOW STOP” go off (on the front panel). Now, the DC is already
ready for the inverter.
(d) Close the (optional) battery breaker - For safety purposes, a breaker (or
fuse) is employed between the batteries and the DC bus. Now the
batteries will take over to supply the DC bus if rectifier mains fail.

MIMIC DISPLAY UNDER NORMAL OPERATION
(e) Push inverter ON switch – To turn 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 seconds. The load will automatically be
transferred to the inverter 3 seconds later. Now the UPS is in
normal operation.
(f) Check if the mimic LED is correct, as shown in the figure, above. All
warning LEDs on the right side are off, two LEDs: ‘INVERTER
ON’ and ‘INVERTER SS’ on the left side should be lit. If the load
is over 70%, the ‘70% LOAD’ LED will also be lit.
4.2. Shutdown Procedure
If you want to shutdown the UPS completely (no power at output or inside),
please follow the steps below.
(a) Switch off the inverter – The inverter can be switched off by pressing the
) and the control switch (
)
inverter OFF switch (
simultaneously. The load will be automatically transferred to
reserve without interruption.
4-2
(b) Open the (optional) 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 – Opening the rectifier breaker will further take
the power source away from the DC bus, and the DC bus will start
to drop slowly. After 5 minutes, the DC bus will drop to a safe
level (< 20VDC).
(d) Open the reserve breaker – Before opening the reserve breaker, power
exists at the output. After opening the reserve breaker, the output
(or load) will no longer have power. Therefore, before opening
the reserve breaker, insure there is no critical load connected to
the output.
(e) If there is input breaker, open it accordingly.
(f) At this point, all power has been cut off, and there should none of the
LED’s or LCD’s lit. The UPS now is completely shut off.
4.3. From Inverter to Maintenance 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.
(a) Switch off the inverter – The inverter can be switched off by pressing the
) and the control switch (
)
inverter OFF switch (
simultaneously. The load will be automatically transferred to
reserve without interruption.
(b) Open the (optional) battery breaker – You have to shutdown the power
inside the UPS. Therefore, continue to open the battery breaker.
4-3
(c) Open the rectifier breaker – Opening the rectifier breaker will take the
power source away from the DC bus, causing the DC bus to drop
slowly. After 5 min., the DC bus will drop to a safe level
(<20VDC).
(d) Close the bypass breaker – The reserve breaker and reserve static switch
are still conducting. Therefore, when the maintenance bypass
breaker is closed, power will flow through the bypass loop instead
of the reserve loop because of the lower impedance of bypass
loop.
(e) Open the reserve breaker – You can now open the reserve breaker to free
the UPS from any power supply.
4.4. From Maintenance 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.
(a) Close the reserve breaker – The reserve and output LED on the mimic will
light, indicating the reserve static switch loop is energized, and
the output has power. The power supply in the UPS is also
established, and the fans will operate.
(b) Open the bypass breaker – The inverter cannot be switched on while the
maintenance bypass breaker is closed (because the CPU will
sense the breaker and prevent the inverter from connecting
directly to AC source). Since the reserve breaker is already closed,
power goes through the reserve loop if the bypass breaker is open.
Thus, AC at the output will not be interrupted.
(c) Close the rectifier breaker - The rectifier will be automatically started if the
power source connected is correct. Wait 30 sec for DC bus
voltage to rise until the warning LEDs of “BAT LOW” and “BAT
LOW STOP” go off (on the front panel). Now, the DC is already
ready for the inverter.
4-4
(d) Close the (optional) battery breaker – For safety purposes, a fuse is
employed in the battery to the DC bus. Now the battery will takeover to supply the DC bus if the rectifier mains fail.
(e) Push inverter ON switch – To turn 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 seconds. The load will automatically be
transferred to the inverter 3 seconds later. Now the UPS is in
normal operation.

5. LCD DISPLAY
The LCD can display much more information than can the LEDs. In order to
make the display sharp and readable, the LCD is back-lighted by LEDs. But to
further prolong the life of the LEDs, the CPU will cut off power to the LEDs 3
minutes after the last keystroke of UP, DOWN or ENTER is pressed. The
backlighting will resume if the UP, DOWN or ENTER key is subsequently
pressed. Page displays of the LCD are described below. This screen will refresh
once the system power is enabled (i.e. the default screen).

6. INTERFACE CONNECTIONS
All interfaces are connected from 3R PCB. See the figure below.
6.1. Dry Contacts
8 terminals of dry contacts are provided (CNR12~20). These terminals are normally
open (non-conducting). When an event occurs, the terminal will close (conduct).
Maximum contact rating is 16A/250VAC(16A/30VDC). The events are shown
below.
INVON – Closed whenever the inverter is on, open when the inverter is off.
OVL – Closed whenever the UPS is overloaded.
6-1
FAULT – Closed when the UPS encounters a fault condition, such as high DC
shutdown, short circuit, fuse/over-heat, overload shutdown, emergency
stop, inverter abnormal, bypass on shutdown. The contact is latched until
manual reset (off switch) or 30 seconds after the fault condition is
removed.
SS – Closed when the inverter static switch is conducting, open when the
reserve static switch is conducting (The two static switches will never
conduct simultaneously).
BYPASS – Closed when the maintenance bypass breaker is closed, open when
the breaker is opened.
BACK-UP – Closed when the inverter (running) is being backed up by the
battery.
BATL – Closed when the inverter is using battery power and the batteries are
about to be exhausted.
COM –This contact can be configured as the OR result of the signals
described above. SWR2-1 (dip-switch pin 1) ~ SWR2-7 (dip-switch pin 7)
can select one of the seven signals described above and SWR2-8 is the
COM enable switch. Please refer to the dip-switch of SWR2 on the 3R
PCB and the following examples and diagram.
6-2
Example 1:
If two contacts for BACK-UP are required. Switch on SWR2-6 & SWR2-8, then
both CNR19 & CNR15 will close when the unit goes to back-up.
Example 2:
If one contact for OVL & FAULT is required. Switch on SWR2-2 & SWR2-3,
then the CNR15 will close when either OVL or FAULT condition happens. Of
course CNR17 will close when OVL happens and CNR13 will close when FAULT
happens.

6.2. External Shutdown
2 pairs of terminals on CNR3 are provided for external shutdown. 10mA is
needed for turning on the internal photo-coupler. The user can use this terminal to
shutdown the UPS when emergency conditions occur, 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. Each connector is especially dedicated to one
type of external module. The following are some connection examples of optional
modules.
CNR21& CNR10 (RS-232)  UPSCOM- Software for PC Monitoring、
SNMP Card. Beside, CNR26 is used as connector for internal SNMP card.

7. OPTIONS
This chapter supplies a brief introduction to all the options that are available for
the 3 Phase UPS. Similar products from other manufacturer will not fit into this
UPS. Additionally, the installation of each option needs professional, trained
personnel.
7.1. Battery Cabinet
The battery cabinet is designed with the same size and profile as the UPS. This is
done for convenience of installation, and for an aesthetically appealing display
when several cabinets of UPS and battery are aligned together. Also, structural
strength is enhanced to endure vibration, shock, etc. during transportation. See the
figure below.
BATTERY CABINET
7-1
7.2. Emergency Power Off Switch (EPO)
An emergency power off (EPO) switch is available as an option, installed outside
but nearby the UPS, for stopping the UPS output in case of emergency, such as
electrical shock, burning of the load or any emergency conditions where one
wants to stop the AC output immediately. When the EPO switch button is pushed,
the inverter immediately stops running, but the static switch remains tied to the
inverter. Therefore there will be no AC supply at the output. This shutdown
condition will be latched until it is manually reset by pressing the OFF () switch
and inverter control switch () simultaneously.
Therefore, please first switch off INVERTER ( push right & middle of inverter
switch simultaneously) and then on INVERTER again (left & middle of inverter
switch simultaneously) to restart the UPS after the EPO is triggered.
7.3. Remote Control Panel – UPSCAN
UPSCAN, remote control panel, is a hand held display module with LCD (the
same as the LCD of the UPS). It is used to switch, on or off, any or all of the UPS
systems. When any UPS encounters an emergency condition, the system 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).
UPSCAN can monitor 1 to 99 units of UPSs with DB9 connections in series
from distance of up to 1000M.
7-2
7.4. Software for PC Monitoring – UPSCOM
UPSCOM is a hardware/software combination installed on a PC to monitor
multiple UPSs with DB9 connection in series. The connector on the UPS’s side is
RS-485 (for long distance transmission); therefore an RS-485  RS-232 adapter
(hardware) is required to modify the signal. The software and hardware together
form a package called UPSCOM. See the UPSCOMTM specification for further
information.
7.5. Battery Monitoring Module - DCMAN
DCMAN is an intelligent module for watching each individual battery in the
battery bank in a simple and direct way. DCMAN can distinguish for repair the
initially aged battery under safe conditions, thus prolonging the battery life
expectancy. One module can monitor up to 64 pieces of 12V battery. DCMAN
will sound an alarm in case of an abnormal situation, such as battery failure, cable
abnormal disconnection, or if the remaining battery charge is less than the
parameter set in the module. See the DCMAN specification for additional
information.
7-3
8. REDUNDANCY
Redundancy can be roughly divided in two types: serial (hot standby) redundancy
and parallel (active) redundancy. The UPS series adopts mainly serial redundancy.
8.1. Serial Redundancy
ONE TO ONE SERIAL REDUNDANCY
Serial (hot standby) redundancy consists of two UPS with one UPS’s (UPS1)
connected to the reserve/bypass input of the other UPS (UPS2). See the above
figure.
8-1
Both UPSs are running in normal mode under normal conditions. When one of
them has a problem, the load will still have protection from the inverter and
battery. If UPS1 fails and UPS2 is running normally, the load is unaffected, and
supplied from UPS2. If UPS2 fails and UPS1 is running normally, UPS2 will
transfer the load to UPS1 and the load will continue to be protected by the
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 multiplies to a
very large MTBF.
This type of redundancy is employed most frequently. When mains fail, UPS2 is
the first to contribute its battery to back-up the load. When UPS2’s batteries are
exhausted, the load is transferred to UPS1. Therefore, this topology can make full
use of the batteries of both units. Users get a system that has redundant protection
and double the back-up time.
Another less expensive solution (see the figure below) is available if the load is
separated. A user may intend to install two UPSs, each with the same power, and
supplying half the load. A third UPS can be installed as backup to two main UPSs.
It is statistically improbable that both main UPSs concurrently break down.
Therefore, the third UPS can serve as a hot standby to two UPSs.
These topologies make full use of the resources to create the best protection and
longest MTBF.
8-2
ONE TO TWO SERIAL REDUNDANCY
8-3
8.2. Parallel Redundancy
The parallel redundancy configuration, like below figure, is designed to increase
both the capacity and reliability. And all the UPS are sharing with equal load.

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 power source (batteries). 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 inside of the UPS.
WARNING !
☆ Be sure to operate the UPS within the rated power level.
☆ 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.
