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.
1.2 Symbols used in this guide
WARNING!
Risk of electric shock
CAUTION!

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 150~600kVA. 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
◆Digital control
◆19-inch standard cabinet
1.2-meter, 1.6-meter and 2-meter high cabinets are provided according to the user’s
requirement.
◆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.
◆3-Stage intelligent charging
◆Touch-screen Super-large LCD display
◆Remote monitoring via SNMP

4
◆Optional Accessories available such as Isolation transformer, distribution Panel, SNMP Card,
Relay Contact Board, etc...
◆Equip with Maintenance Bypass Switch for easy maintenance purpose.
