The UPS system consists of a rectifier, battery bank, inverter, static switch, circuit
breaker, monitoring, and indicators.

Normal Operation:
In normal operational conditions, the UPS receives AC power and consequently
transforms to DC power through rectifier for charging battery and supplying inverter.
The inverter transforms DC power to stable and clean AC power for the various
loads.
When the utility AC power is absent, the battery will instantly provide DC power to
inverter for continuous operation. Hence, the UPS output will not be interrupted for
insuring normal operation of the load.

Reserve AC Supply Mode:

When the inverter in abnormal situations, such as over temperature, short circuit,
abnormal output voltage, the inverter will shutdown due to self-protection function. If
the utility power is normal, the static switch shall transfer the load to the reserve
source without interruption of power supply.

1
 Maintenance Bypass mode:
During maintenance, turning off the inverter and all circuit breakers except the
maintenance bypass switch keeps continuously power supply to the load. Risk will
not exist in UPS for making sure safety of service personnel.

Note !
If only single mains power is available, please utilize the same power source for
reserve AC input and rectifier input.

Rectifier 2

The rectifier transforms AC power to DC power and supplies to inverter, battery charger.
Its input is protected by circuit breaker and current sensor that can protect input from over
current. It also has the function of steady current charging (current limit is adjustable). The
large capacity models can have option for 2 sets of rectifier (12 pulse rectifier) to reduce
the harmonics of input current.

Another function of the rectifier is to charge the battery and the charge voltage can set in
floating mode or boost mode. If the battery is discharged under 2 volts per cell and AC
utility restores, the rectifier automatically goes into the boost mode and supplies sufficient
current to charge the battery for the purpose of extending battery life and insuring the
battery in a full charged condition.(The time of boost charge is adjustable).

To prevent the disturbance surges and inrush current of the input AC power source, the
rectifier is soft started and DC bus voltage is set up over a time period of 20 seconds.

The purpose of the inverter is to convert the DC output of the rectifier or battery into AC
power for accommodating different loads under all conditions. The inverter consists of
IGBT transistors with full bridge circuit which is under control by sinusoidal pulse-width
modulation (SPWM).

The frequency of the inverter is maintained in a phase locked condition with the reserve
input frequency as long as the reserve input frequency is with in a predetermined
tolerance of nominal. If the frequency of utility power is beyond the predetermined
tolerance, logical control circuit will lock phase using the crystal oscillating frequency.

The inverter has the protection of short circuit, over load and over temperature. The
acceptable DC input range is between 300 and 400 Vdc, and the inverter output is
connected to static switch.

Static Switch

The static switch consists of SCR, and its function is to transmit the inverter AC output to
external load.

When following conditions occur: 1.UPS shutdown due to DC low voltage, 2.Over
temperature or fuse failure, 3.Inverter output over the permitted tolerance, 4.Inverter
malfunction, 5.Inverter serious overload, the load will automatically transfer to the
reserved AC source. When the over load condition is disappear, the static switch will
again turn back the load to inverter. When reserved AC source voltage or frequency is
over the permitted tolerance, the static switch will not transfer the load to reserved AC
source.

When the UPS needs to be maintained, service personnel can consequently operate the
UPS in bypass mode. The internal circuit is completely isolated from AC supply, and
protects service personnel from electric shock.

2. Instructions for Installation

2.1 Location Environment and Safety Precaution

For ensuring UPS normal operation , prolonging UPS lifetime, and protecting UPS
from disorder and malfunction, user should select optimal installing location and
environment according to the following instructions, and observe the noticed items
of safety.
1. The weight of the UPS system (see paragraph 1.8) is concentrated on a
relatively small floor area due to the cabinet design. The installing location must
therefore have a sufficient floor loading capacity adequate to bear the load.
2. The UPS should be located on place with good ventilation. Its rear panel should
be kept away from wall at least 50 cm. A space of about 1m should be kept clear
in front of the UPS to provide room for both operation and maintenance.
3. The UPS is capable of continuous normal operation with in a temperature range
of 0℃to 40℃( 32°F to 104°F). For optimum performance and reliability to prolong
UPS lifetime, the temperature should be kept below 25 ℃environment, and
humidity must be maintained within a range of 0 to 95% (non-condensing).

For decreasing the dangerous due to accident, following rules should be observed.
1. Walls, ceiling, floors as well as everything surrounding or near the UPS should
be preferably constructed of noncombustible materials. The room should be
equipped with a portable fire extinguisher.
2. Litter or trash of any sort should not be allowed to accumulate 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.
3. 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 controlled to authorized personnel only.
4. All personnel who operate or maintain the UPS system should be proficient in
normal and emergency operational procedures. New personnel should be trained
and tested prior to operating the equipment.

boost charge function.

3.2 System Start-up procedure

Please check the following noticed items before UPS start-up:
1. All circuit breakers and isolators are in off position and battery fuse is out.
2. Ensure that neutral line and grounding are the same voltage level.
3. Apply power to the AC input cables and check that input voltage, frequency and
phase order are with in the machine specifications.
When UPS comply with the above mentioned conditions, start-up UPS according to the
following procedure:
1. Close “ MANUAL BYPASS ” breaker, at the same time LCD display ” LOAD ON
BYPASS ”.
2. Close “ AC INPUT ” and “ RECTIFIER INPUT ” breaker，wait 15～20 seconds
until “ BATT LOW ” LED behind the door is off.
3. Close “ RESERVED INPUT ” breaker, at the same time LCD display ” LOAD
ON RESERVE ”.
4. Close “ UPS OUTPUT ” breaker.
5. OPEN “ MANUAL BYPASS ” breaker.
6. Close “ BATTERY FUSE ISOLATOR ” in battery cabinet.
7. Press the inverter “ON” & “ ” button simultaneously, the load will be
transferred from reserve to inverter automatically, at the same time LCD
display ” LOAD ON INVERTER ”.

21
 Note: It must nerver turn on “manual bypass” circuit breaker when the
inverter is turned on. It will damage the UPS owing to utility power
parallel with inverter output.

3.3 Maintenance Manual Bypass Procedure

This procedure leaves the critical load undisturbed and the UPS batteries still being
charged.
1. Check “ MAIN FREQ ABNORMAL ” “ RES MAIN FAIL ” LEDS behind the door
are all off.
2. Press inverter “ OFF ” & “ ”button simultaneously. Check that “ INV ON ” LED
behind the door is off.
3. Close “ MANUAL BYPASS ” breaker.
4. OPEN “ UPS OUTPUT ” breaker.
5. OPEN “ RESERVE INPUT ” breaker.

3.4 Return from Bypass to Normal Mode

This operating procedure will transfer load from bypass to normal mode as follows:
1. Check that “ INV ON ” LED behind the door is off.
2. Close “ RESERVE INPUT ” breaker.
3. Close “ UPS OUTPUT ” breaker.
4. Open “ MANUAL BYPASS ” breaker.
5. Press the inverter “ ON ” & “ ” button simultaneously.
6. The load will be transferred from reserve to inverter automatically.

3.5 System Shutdown Procedure

This operating procedure can turn off power supply to UPS, please first confirm the
load has been shutdown, the procedures as follows：
1. Press inverter “OFF” & “ ” button simultaneously，Check that “INV ON ”LED
behind the door is off.
2. Close “ MANUAL BYPASS ” breaker.
3. Open “ BATTERY FUSE ISOLATOR ” in battery cabinet.

4. Maintenance

To increase system reliability, please according to the following notice do the cyclical
maintenance:

1. Blowers or fans, mounted in the top of the system, should be checked for proper
operation at monthly intervals. Improper blower operation can cause a rise in
system operating temperature resulting in an over temperature shutdown.

2. Cable connections to circuit breakers and other terminals should be checked for
discoloration produced by overheating also at monthly intervals.

3. Every 6 Months a qualified service engineer should check the machines electronic
settings and take any appropriate action to ensure the long term reliability of the
UPS.
