1.Important Safety Precautions
General Information
Please read the "safety precautions" carefully before installing and using this
product to ensure correct and safe installation and use. Please keep this manual
properly.
UPS must be installed, tested and maintained by an engineer authorized by the
manufacturer or its agent, otherwise it is possible to endanger personal safety and
cause equipment failure. The damage to UPS caused thereon is excluded from the
warranty.
Under no circumstances shall equipment structure or components be dismantled
or changed without the manufacturer's permission, otherwise the damage to UPS
caused thereby shall not be covered by the warranty.
Local regulations and laws shall be followed when using equipment. The safety
precautions in the manual only supplement the local safety regulations.
Due to product version upgrade or other reasons, the content of this document
will be updated from time to time. Unless otherwise agreed, this document is used
only as a guide, and all statements, information and recommendations in this
document do not constitute any warranty, express or implied.
UPS Safety
Before installing the equipment, wear insulating protective clothing, use
insulating appliances, and remove conductive objects such as jewelry and
watches to avoid electric shock or burns.
The operating environment has a certain impact on the service life and reliability
of UPS. The environmental requirements set in the manual must be followed
when using and storing the equipment.
Avoid using the equipment in direct sunlight, rain, or in environments with
electrified dust.
When placing UPS, maintain a safe distance around it to ensure ventilation.
During operation of the system, do not block the vent.
Do not allow liquids or other foreign objects to enter into the UPS cabinet or
cabinet.
Before using UPS, check whether the local distribution characteristics are
consistent with the information of the product nameplate.
As UPS is a large leakage current device, it is not recommended to install
breakers with leakage protection function.
Before connecting UPS, please further confirm whether the switch connecting the
power supply of the UPS mains input/bypass power supply and the mains power
are disconnected.
When it is required to move or rewire UPS, make sure to disconnect AC input
power supply, battery and other inputs, and UPS is fully powered down (more
than 5min) before carrying out the corresponding operation, otherwise there may
still be power in the port and inside of the equipment, and it is possible to cause a
risk of electric shock.
Before powering on, please confirm the correct grounding, and check wire
2
connection and battery polarity to ensure correct connection. In order to ensure
personal safety and the normal use of UPS, UPS shall be reliably grounded before
use.
UPS can be used for resistive and capacitive (such as computers), resistive and
micro inductive load, not for pure capacitive and inductive load (such as motors,
air conditioners and copiers) and half wave rectifier load.
When cleaning the machine, please wipe it with a dry object. Under no
circumstances shall water be used to clean electrical parts inside or outside the
cabinet.
After completion of maintenance operations, check immediately to ensure that no
tools or other items are left in the cabinet.
In case of fire, please use dry powder extinguisher correctly for extinguishment.
There is a danger of electric shock if liquid fire extinguishers are used.
Do not close the breaker before the UPS installation is completed. Do not power
on UPS without the permission of a qualified electrician.
Battery Safety
Battery installation and maintenance shall only be performed by personnel with
battery expertise.
There is danger of electric shock and short circuit current in the battery. In order
to avoid safety accidents, when installing or replacing the battery, please pay
attention to the following matters: do not wear jewelry and watches and other
conductive objects; use special insulation tools; use facial protection; wear
protective insulating clothing; do not turn the battery upside down or tilt it;
disconnect the input breaker of the battery.
The installation environment of the battery must be far away from the hot area,
and it is not allowed to use or keep the battery near the fire source. The battery or
battery strings cannot be processed by fire, otherwise it is possible cause personal
injury due to explosion.
Environmental factors impact battery life. Elevated ambient temperatures, poor
quality utility power, and frequent short duration discharges will shorten battery
life.
The batteries should be regularly replaced to ensure the normal operation of UPS
and sufficient backup time.
Do not use a battery that is not approved by the supplier, as it may adversely
affect the operation of the system. Use of a non supplier approved battery will
void the manufacturer warranty.
Check the screws of the connecting parts of the battery regularly to make sure
they are tight and not loose. If the screws become loose parts, they must be
tightened immediately.
Please do not short the positive and negative terminals of the battery, Otherwise it
is possible to cause electric shock or fire.
Do not touch the wiring terminal of the battery. The battery circuit is not isolated
from the input voltage circuit, and there will be a high voltage hazard between the
battery terminal and the ground.
Do not open or damage the battery, otherwise it is possible to cause short circuit
and battery leakage and the electrolyte in the battery may cause damage to the
3
skin and eyes. In case of exposure into the electrolyte, wash immediately with
plenty of water and go to the hospital for examination.

2. Product Introduction
2.1 Introduction
The UPS supplies stable and uninterrupted power for the important load. It can
eliminate the power supply surge, instantaneous high/low voltage, harmonic and
frequency offset pollution, to provide high quality electrical energy to costomers.
2.2 System Configuration
The Tower UPS is configured by the following part: Rectifier, Charger, Inverter,
Static Switch and Manual Bypass Switch. One or several battery strings should be
installed to provide backup energy once the utility fails. The UPS structure is shown
in Fig. 2-1.
Fig. 2-1 UPS Configuration
2.3 Operation Mode
The UPS is an on-line, double-conversion UPS that permits operation in the following
modes:
Normal mode
Battery mode
Bypass mode
Maintenance mode (manual bypass)
ECO mode
Auto-restart mode
Frequency Converter mode
Self Aging Mode
2.3.1 Normal Mode
The inverter of power modules continuously supply the critical AC load. The
rectifier/charger derives power from the AC mains input source and supplies DC
power to the inverter while simultaneously FLOAT or BOOST charging its associated
backup battery.
5
Fig 2-2 Normal mode operation diagram
2.3.2 Battery Mode
Upon failure of the AC mains input power, the inverter of power modules, which
obtain power from the battery, supply the critical AC load. There is no interruption in
power to the critical load upon failure. After restoration of the AC mains input power,
the “Normal mode” operation will continue automatically without the necessity of
user intervention.
Fig 2-3 Battery mode operation diagram
Note
With the function of Battery cold start, the UPS may start without utility. See more detail in
section 5.1.2.
2.3.3 Bypass Mode
If the inverter overload capacity is exceeded under Normal mode, or if the inverter
becomes unavailable for any reason, the static transfer switch will perform a transfer
of the load from the inverter to the bypass source, with no interruption in power to the
critical AC load. Should the inverter be asynchronous with the bypass, the static
switch will perform a transfer of the load from the inverter to the bypass with power
interruption to the load. This is to avoid large cross currents due to the paralleling of
unsynchronized AC sources. This interruption is programmable but typically set to be
less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms
(60Hz). The action of transfer/re-transfer can also be done by the command through
monitor.

Fig. 2-4 Bypass mode operation diagram
2.3.4 Maintenance Mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load
when the UPS becomes unavailable e.g. during a maintenance procedure. (See
Fig.2-5).
Fig .2-5 Maintenance mode operation diagram
Danger
During Maintenance mode, dangerous voltages are present on the terminal of input, output and
neutral, even with the LCD turned off.
2.3.5 ECO Mode
To improve system efficiency, UPS rack system works in Bypass mode at normal
time, and inverter is standby. When the utility fails, The UPS transfers to Battery
Mode and the inverter powers the loads.
