Battery Safety
Danger
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 400Vdc 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°C. Operating above this temperature will
reduce the battery life. Periodically charge 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 the battery. 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
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.
Do not 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

The series rack-mountable UPS using on-line double conversion design and DSP
based digital control. It 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 customers.
1.1 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. 1-1.
Fig.1-1 UPS Configuration
1.2 Operation Mode
The Tower UPS is an on-line, double-conversion UPS that permits operation in the
following modes:
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.

1.2.2 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.1-3 Battery mode operation diagram
1.2.3 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.1-4 Bypass mode operation diagram
1.2.4 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.1-5).

Note
There is a short interruption time (less than 10ms) when transfer from ECO mode to battery
mode, it must be sure that the interruption has no effect on loads.
1.2.6 Auto-restart Mode
The battery may become exhausted following an extended AC mains failure. The
inverter shuts down when the battery reaches the End of Discharge Voltage (EOD). The
UPS may be programmed to “System Auto Start Mode after EOD”. The system starts
after a delay time when the AC main recovers. The mode and the delay time are
programmed by the commissioning engineer.

Chapter 5 Maintenance
Chapter 5 Maintenance
This chapter introduces UPS maintenance, including the maintenance instructions of power
module and monitoring bypass module and the replacement method of dust filter.
5.1 Precautions
1. Only certified engineers are authorized to maintain the UPS.
2. The components or PCBs should be disassembled from top to bottom, so as to prevent any
inclination from high gravity center of the cabinet.
3. To ensure the safety before maintaining, measure the voltage between operating parts and
the earth with multi-meter to ensure the voltage is lower than hazardous voltage, i.e. DC
voltage is lower than 60Vdc, and AC maximum voltage is lower than 42.4Vac.
4. Wait 10 minutes before opening the cover of the power module or the bypass after pulling
out from the Cabinet.
5.2 Instruction for Maintaining UPS
For the maintenance of the UPS, please refer to chapter 4.2.4 for the instruction to transfer
to maintenance bypass mode.
5.3 Instruction for Maintaining Battery string
For the Lead-Acid maintenance free battery, when maintenance the battery according to
requirements, battery life can be prolonged. The battery life is mainly determined by the
following factors:
1. Installation. The battery should be placed in dry and cool place with good ventilation.
Avoid direct sunlight and keep away from heat source. When installing, ensure the correct
connection to the batteries with same specification.
2. Temperature. The most suitable storage temperature is 20 ºC to 25ºC. The battery life will
be shortened if the battery is used under high temperature or in deep discharging status.
Refer to product manual for details.
3. Charging/discharging current. The best charging current for the lead-acid battery is
0.1C .The maximum current for the battery can be 0.3C.The suggested discharging
current is 0.05C-3C.
4. Charging voltage. In most of the time, the battery is in standby state. When the utility is
normal, the system will charge the battery in boost mode (Constant voltage with
maximum limited) to full and then transfers to the state of float charge.
5. Discharge depth. Avoid deep discharging; which will greatly reduce the life time of the
battery. When the UPS runs in battery mode with light load or no load for a long time, it
will cause the battery to deep discharge.
6. Check periodically. Observe if any abnormality of the battery, measure if the voltage of
each battery are in balance. Discharge the battery periodically.
Warning
Daily inspection is very important!
Check and confirm the battery connection is tightened regularly, and make sure there is no
abnormal heat generated from the battery.

Chapter 5 Maintenance
Warning
If a battery has leakage or is damaged, it must be replaced, stored in a container resistant to
sulfuric acid and disposed of in accordance with local regulations.
The waste lead-acid battery is a kind of hazardous waste and is one of the major contaminants
controlled by government.
Therefore, its storage, transportation, use and disposal must comply with the national or local
regulations and laws about the disposal of hazardous waste and waste batteries or other
standards.
According to the national laws, the waste lead-acid battery should be recycled and reused, and
it is prohibited to dispose of the batteries in other ways except recycling. Throwing away the
waste lead-acid batteries at will or other improper disposal methods will cause severe
environment pollution, and the person who does this will bear the corresponding legal
responsibilities.
