Safety Precautions
This manual contains information concerning the installation and operation of UPS. Please carefully
read this manual prior to installation.
The UPS cannot be put into operation until it is commissioned by engineers approved by the
manufacturer (or its agent). Not doing so could result in personnel safety risk, equipment
malfunction and invalidation of warranty.
Safety Message Definition
Danger: Serious human injury or even death may be caused, if this requirement is ignored.
Warning: Human injury or equipment damage may be caused, if this is requirement is ignored.
Attention: Equipment damage, loss of data or poor performance may be caused, if this requirement
is ignored.
Commissioning Engineer: The engineer who installs or operates the equipment should be well
trained in electricity and safety, and familiar with the operation, debug, and maintenance of the
equipment.
Warning Label
The warning label indicates the possibility of human injury or equipment damage, and advised the
proper step to avoid the danger. In this manual, there are three types of warning labels as below.
Labels Description
Serious human injury or even death may be caused, if this requirement
is ignored.
Human injury or equipment damage may be caused, if this requirement is
ignored.
Equipment damage, loss of data or poor performance may be caused, if
this requirement is ignored.
Safety Instruction
⟡Performed only by commissioning engineers.
⟡This UPS is designd for commercial and industrial applications
only, and is not intended for any use in life-support devices or
system.
⟡Read all the warning labels carafully before operation, and follow
the instructions.
3
⟡When the system is running , do not touch the surface with this
label, to avoid any hurt of scald.
⟡ESD sensitive components inside the UPS, anti-ESD measure
should be taken before handling.
Move & Installation
⟡Keep the equipment away from heat source or air outlets.
⟡In case of fire, use dry powder extinguisher only, any liquid
extinguisher can result in electric shock.
⟡Don’t start the system if any damage or abnormal parts founded.
⟡Contacting the UPS with wet material or hands may be subject to
electric shock.
⟡Use proper facilities to handle and install the UPS. Shielding shoes,
protective clithes and other protective facilities are necessary to
aviod injury.
⟡During positioning, keep the UPS way from shock or vibration.
⟡Install the UPS in proper environment, more detail in section 2.3.
Debug & Operate
⟡Make sure the grounding cable is well connected before
connecting the power cables, the grounding cable and neutral
cable must be in accordance with the local and national codes
practice.
⟡Before moving or re-connecting the cables, make sure to cut off
all the input power sources, and wait for at least 10 minutes for
internal discharge. Use a multi-meter to measure the voltage on
terminals and ensure the voltage is lower than 36V before
operation.
⟡The earth leakage current of load will be carried by RCCB OR
RCD.
⟡Initial check and inspection should be performed after long time
storing of UPS.
Maintenance & Replacement
⟡All the equipment maintenance and servicing procedures
involving internal access need special tools and should be carried
out only by trained personnel. The components that can be
accessed by opening the protective cover with tools cannot be
maintenance by user.
4
⟡This UPS full complies with “IEC62040-1-1-General and safety
requirements for use in operator access area UPS”. Dangerous
voltages are present within the battery box.
However, the risk of contact with these high voltages is minimized
for non-service personnel. Since the component with dangerous
voltage can only be touched by opening the protective cover with
a tool, the possibility of touching high voltage component is
minimized. No risk exists to any personnel when operating the
equipment in the normal manner, following the recommended
operating procedures in this manual.
Battery Safety
⟡All the battery maintenance and servicing procedures
involving internal access need special tools or keys and
should be carried out only by trained personnel.
⟡When connected together, the battery terminal voltage will
exceed 200Vdc and is potentially lethal.
⟡Battery manufacturers supply details of the necessary
precautions to be observed when working on, or in the
vicinity of a large bank of battery cells. These precautions
should be followed implicitly at all times. Particular attention
should be paid to the recommendations concerning local
environmental conditions and the provision of protective
clothing, first aid and fire-fighting facilities.
⟡Ambient temperature is a major factor in determining the
battery capacity and life. The nominal operating temperature
of battery is 20℃. Operating above this temperature will
reduce the battery life. Periodically change the battery
according to the battery user manuals to ensure the back-up
time of UPS.
⟡Replace the batteries only with the same type and the same
number, or it may cause explosion or poor performance.
⟡When connecting the battery, follow the precautions for high-
voltage operation before accepting and using the battery,
check the appearance of the batteries. If the package is
damaged, or the battery terminal is dirty, corroded or rusted
or the shell is broken, deformed or has leakage, replace it
with new product. Otherwise, battery capacity reduction,
electric leakage or fire may be caused.
⟡Before operating the battery, remove the finger ring, watch,
necklace, bracelet and any other metal jewelry.
⟡Wear rubber gloves.
⟡Eye protection should be worn to prevent injury from
5
accidental electrical arcs.
⟡Only use tools (e.g. wrench) with insulated handles.
⟡The batteries are very heavy. Please handle and lift the
battery with proper method to prevent any human injury or
damage to the battery terminal.
⟡Don’t decompose, modify or damage the battery. Otherwise,
battery short circuit, leakage or even human injury may be
caused.
⟡The battery contains sulfuric acid. In normal operation, all
the sulfuric acid is attached to the separation board and plate
in the battery. However, when the battery case is broken, the
acid will leak from the battery. Therefore, be sure to wear a
pair of protective glasses, rubber gloves and skirt when
operating the battery. Otherwise, you may become blind if
acid enters your eyes and your skin may be damaged by the
acid.
⟡At the end of battery life, the battery may have internal short
circuit, drain of electrolytic and erosion of positive/negative
plates. If this condition continues, the battery may have
temperature out of control, swell or leak. Be sure to replace
the battery before these phenomena happen.
⟡If a battery leaks electrolyte, or is otherwise physically
damaged, it must be replaced, stored in a container resistant
to sulfuric acid and disposed of in accordance with local
regulations.
⟡If electrolyte comes into contact with the skin, the affected
area should be washed immediately with water.
Disposal
⟡Dispose of used battery according to the local instructions.

1.2.2 Operation Mode
The tower 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
1.2.2.1 Normal Mode
The inverter of UPS continuously supply the critical AC load. The rectifier/charger derives power
from the AC main input source and supplies DC power to the inverter while simultaneously
FLOAT or BOOST charging its associated backup battery. The Normal mode structure is shown in
Fig.1-4.
Figure 1-4 Normal mode operation diagram
1.2.2.2 Battery Mode
Upon failure of the AC main input power, the inverter of UPS, which obtains 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. The Battery mode structure is shown in Fig.1-5.
