1．Safety
Important safety instructions – Save these instructions
There exists dangerous voltage and high temperature inside the UPS. During the
installation, operation and maintenance, please abide the local safety instructions and relative
laws, otherwise it will result in personnel injury or equipment damage. Safety instructions in this
manual act as a supplementary for the local safety instructions. Our company will not assume the
liability that caused by disobeying safety instructions.
1.1 Safety notes
1． Even no connection with utility power, 220/230/240VAC voltage may still exist at UPS outlet!
2． For the sake of human being safety, please well earth the UPS before starting it.
3． Don’t open or damage battery, for the liquid spilled from the battery is strongly poisonous
and do harmful to body!
4．Please avoid short circuit between anode and cathode of battery, otherwise, it will cause
spark or fire!
5．Don’t disassemble the UPS cover, or there may be an electric shock!
6．Check if there exists high voltage before touching the battery
7．Working environment and storage way will affect the lifetime and reliability of the UPS. Avoid
the UPS from working under following environment for long time
◆ Area where the humidity and temperature is out of the specified range (temperature 0
to 40℃, relative humidity 5%-95%)
◆ Direct sunlight or location nearby heat
◆ Vibration Area with possibility to get the UPS crashed.
◆ Area with erosive gas, flammable gas, excessive dust, etc
8．Keep ventilations in good conditions otherwise the components inside the UPS will be
over-heated which may affect the life of the UPS.

2．Main Features
2.1 Summarization
Our UPS is a kind of three-in- three -out high frequency online UPS, it provides three
specifications: The 30~150kVA. The products are modularized and adopt the N+X redundancy. It
can flexibly increase the number of the UPS modules according to the load capacity which is
convenient for flexible allocation and gradually investment.
The UPS can solve most of the power supply problems, such as blackout, over-voltage,
under-voltage, voltage sudden drop, oscillating of decreasing extent, high voltage pulse, voltage
fluctuation, surge, inrush current, harmonic distortion (THD), noise interference, frequency
fluctuation, etc..
This UPS can be applied to different applications from computer device, automatic
equipment, communication system to industry equipment.
2.2 Functions and Features
◆ Rack modular design
Modular design, compatible with 19” standard rack cabinet, convenient to be integrated with
servers.
◆ Integrated solution for data center
◆ Digital control
◆ Modularized design
◆ High power-density design
◆ The height of the single module is 3U.
◆ N+X parallel redundancy
This series UPS adopts N+X parallel redundancy design, user can set different redundancy
according to the importance of the load. While the redundancy modules are set more than
two, the availability of UPS system will achieve 99.999%, which may satisfy the required
reliability of the critical load connected. Through LCD display setting, you may configure the
required quantity of the redundancy unit. When the load connected is over the number of the
redundancy, the UPS will alert right away. The design of the MTBF (Meantime before Failure)
is up to 250,000 hours.
This series can set the number of redundancy modules. When the load exceeds the
redundancy setting, the UPS can still work normally and simultaneously send out
corresponding warning as long as the load doesn’t exceed the total capacity of modules.
◆ Parallel redundant control system
◆ Optimizing distributed convergence for the cabinet
◆ Centralized bypass
◆ Common Battery
◆ Automatic charge current adjustment according to battery capacity connected.

◆ Centralized monitoring module is also available
◆ EPO and REPO function
3．Installation
3.1 Unpack checking

3.5 Installation notes
Note: Consider for the convenience of operation and maintenance, the space in
front and back of the cabinet should be left at least 800mm and 800mm respectively
when installing the cabinet.

19
◆Please place the UPS in a clean, stable environment; avoid the vibration, dust, humidity,
flammable gas and liquid, corrosive. To avoid from high room temperature, a system of room
extractor fans is recommended to be installed. Optional air filters are available if the UPS operates
in a dusty environment.
◆The environment temperature around UPS should keep in a range of 0℃～40 . If the ℃
environment temperature exceeds 40 , the rated load capacity should ℃be reduced by 12％ per
5 . The max temperature can't be higher than 50 .℃℃
◆If the UPS is dismantled under low temperature, it might be in a condensing condition. The
UPS can't be installed unless the internal and external of the equipment is fully dry. Otherwise,
there will be in danger of electric shock.
◆Batteries should be mounted in an environment where the temperature is within the required
specs. Temperature is a major factor in determining battery life and capacity. In a normal
installation, the battery temperature is maintained between 15°C and 25°C. Keep batteries away
from heat sources or main air ventilation area, etc.
WARNING!
Typical battery performance data are quoted for an operating temperature between
20°C and 25°C. Operating it above this range will reduce the battery life while
operation below this range will reduce the battery capacity.
◆Should the equipment not be installed immediately it must be stored in a room so as to
protect it against excessive humidity and or heat sources.
CAUTION!
An unused battery must be recharged every 6months temporarily connecting the
UPS to a suitable AC supply mains and activating it for the time required for
recharging the batteries.
