3. Introduction
3.1 Functions description
This product is a true online double-conversion UPS (Uninterruptible Power
Supply). It provides perfect protection for critical load such as computer system. It
can eliminate almost all mains power disturbances. The input AC current can be
corrected to a wave following the mains voltage, so it is a high power factor
system. Through the PWM control technology, the output voltage can be a pure &
stable sine wave AC voltage.
When the mains input become abnormal, the controller will stop the AC/DC and start the
DC/DC section immediately to make sure the DC/AC (inverter) section can continue to
work. After the mains input comeback to normal range, the DC/DC will be stopped and
the AC/DC works again. So the load is always power-supplied through inverter without
any interrupt if the UPS is turned on.
The UPS also provides an internal bypass way to make the load can be powered by mains
input directly when the UPS is off or failed.
The UPS have an internal charger for batteries, the charger will charge the batteries when
the mains is in a reasonable range on “bypass mode” or “line mode”.

4) After having completed the installation, make sure the wiring is correct.
5) Please install the leak current protective breaker at the output power
distribution panel of the UPS if necessary.
6) To connect the load with the UPS, please turn off all the loads first, then
perform the connection and finally turn on the loads one by one.
7) No matter the UPS is connected to the utility power or not, the output of the
UPS may have electricity. The parts inside the unit may still have hazardous
voltage after turning off the UPS. To make the UPS have no output, power off the
UPS, and then disconnect the utility power supply.
8) It is suggested to charge batteries for 8 hours before use. After connection,
turn the input breaker to the “ON” position, and then UPS will charge batteries
automatically. You can also use the UPS immediately without charging the
batteries first, but the backup time may be less than the standard value.
9) If it is necessary to connect the inductance load such as a monitor or a laser
printer to the UPS, the start-up power should be used for calculating the capacity
of the UPS, as its start-up power consumption is too big when it is started.
3.6 Operating procedure for connecting the long backup time
model UPS with the external battery
1) The nominal DC voltage of external battery pack is 240VDC. Each battery
pack consists of 20 pieces of 12V maintenance free batteries in series.
To achieve longer backup time, it is possible to connect multi-battery packs, but
the principle of “same voltage, same type” should be strictly followed.
2) The connector of the external battery cable is used to plug into the external
battery socket of the UPS, the other end of the external battery cable is connected
to the external battery pack(s). The procedure of installing battery bank should be
complied with strictly. Otherwise you may encounter the hazardous of electric
shock.
(1) A DC breaker must be connected between the battery pack and the UPS.
The capacity of breaker must be not less than the data specified in the general
specification.

The UPS provides useful information about UPS itself, load status, events,
measurements, identification, and settings through the front panel display.
During powering on, the LCD would display the “WELCOME”logo for several
seconds and then enter to the default page which shows the UPS status
summary.
The display automatically returns to the default UPS status summary screen when
no button has been pressed for 15 minutes.
On the UPS status summary screen it provides the following information:
1) Status summary, including mode and load.
2) Alarm status, including fault and warning information.
3) Battery and charger status, including battery voltage, charge level and
charger status.
4) Running information of UPS running time.
5) Running information of parallel UPS (Rackmount UPS model available).
The more detailed operation of LCD is illustrated in the 5.4 chapter.
5.2 Operating Mode
The different graphic symbol could be displayed corresponding to current
operating mode or status.
5.2.1 Line mode
Line mode means that the mains input is rectified/converted by the AC/DC section
and then inverted to stable output by DC/AC section. In line mode, the output is
clean and good to the loads. If the mains get abnormal, the UPS will transfer to
battery mode without interrupt. The example of LCD display in Line mode is
shown in the following diagram.

24

5.2.2 Battery mode
Battery mode means that the battery power goes through the DC/DC section to
the inverter (DC/AC) and get a stable backup output when the mains input is not
usable. If the mains input recovered, the UPS will transfer to line mode without
interrupt. The example of LCD display in battery mode is shown in the following
diagram.

When the UPS is running in battery mode, the buzzer beeps once every 4
seconds.
5.2.3 Bypass mode
Bypass mode means that the UPS provides the power through the internal bypass
way to load directly without any regulation. If the controller detects the mains is
abnormal, it will shut off the output to protect the load. The UPS bypass
voltage/frequency range could be set by communication software. However, UPS
output power will be cut off if mains input range exceeds the setting value. The
UPS bypass default output status (on/off) could also be set by communication
software.
The UPS does not have the backup function when it is in bypass mode. The UPS
will beep once every 2 minutes in bypass mode.

It is also called economy mode. After the UPS is turned on, the power used by the
load is supplied from the mains power via internal filter while the mains power is in
normal range, so the high efficiency could be gained in the HE mode. Once the
mains power is loss or abnormal, the UPS would transfer to Line mode or Battery
mode and the load is supplied continuously.
