1.2 Product Introduction
1.2.1 UPS System Description
The Rack UPS is configured by the following part: Rectifier, Charger, Inverter, Static bypass switch.
One or several battery strings should be installed to provide backup energy once the utility fails.
The UPS structures are shown in Figure 1-3.
Figure 1-3 UPS Block Diagram

9
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.

10
Figure 1-5 Battery Mode operation diagram
Note: With the function of “Battery Cold Start”, the UPS could start without utility. See more detail
in section5.1.2.
1.2.2.3 Bypass Mode
If the overload capacity of the inverter 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. The
Bypass mode structure is shown in Fig.1-6.
Figure 1-6 Bypass mode operation diagram

11
1.2.2.4 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. The Maintenance mode structure is
shown in Fig.1-7.
Figure 1-7 Maintenance mode operation diagram
Danger
During Maintenance mode, dangerous voltages are present on the terminal of input, output and
neutral, even with all the modules and the LCD turned off.
1.2.2.5 ECO Mode
To improve system efficiency, UPS system works in Bypass Mode at normal time, and the inverter
is standby, when the utility from the bypass fails, the UPS will transfer to Battery Mode and the
inverter powers the load. The ECO mode structure is shown in Fig.2-8.
Figure 1-8 ECO Mode operation diagram

12
Note
There is a short interruption time (less than 10ms) when transferring from ECO mode to battery
mode, it must be sure that the interruption has no effect on loads.
1.2.2.6 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 mains
recover. The mode and the delay time are programmed by the commissioning engineer.
1.2.2.7 Frequency Converter Mode
By setting the UPS to “Frequency Converter Mode”, the UPS could present a stable output of fixed
frequency (50 or 60HZ), and the bypass static switch is not available.

2 Installation
This chapter introduces UPS installation, including unpacking and inspection, main Cabinet
Installation, cables connection.
2.1 Location
As each site has itself requirements, the installation instructions in this section are as a guide for the
general procedures and practices that should be observed by the installing engineer.
2.1.1 Installation Environment
The UPS is intended for indoor installation and uses forced convection cooling by internal fans.
Please make sure there is enough space for the UPS ventilation and cooling.
Keep the UPS far away from water, heat and inflammable and explosive corrosive material. Avoid
installing the UPS in the environment with direct sunlight, dust, volatile gases, corrosive material
and high salinity.
Avoid installing the UPS in the environment with conductive dirt.
The operatingenvironmenttemperaturefor batteriesis 20℃-25℃. Operating above 25℃will reduce
the battery life, and operation below 20℃will reduce the battery capacity.
The battery will generate a little amount of hydrogen and oxygen at the end of charging; ensure the
fresh air volume of the battery installation environment must meet EN50272-2001 requirements.
When external batteries are used, the battery circuit breakers (or fuses) must be mounted as close as
possible to the batteries, and the connecting cables should be as short as possible.
2.1.2 Site Selection
Ensure the ground or installation platform can bear the weight of the UPS cabinet, batteries and
battery racks.
No vibration and less than 5 degree inclination horizontally.
The equipment should be stored in a room so as to protect it against excessive humidity and heat
sources.
The battery needs to be stored in dry and cool place with good ventilation. The most suitable storage
temperatureis 20℃to 25℃.
