Warning: This is a product for commercial and industrial application in the second
environment-installation restrictions or additional measures may be needed to
prevent disturbances.
WARNING: This is a category C2 UPS product. In a residential environment, this product
may cause radio interference, in which case the user may be required to take additional
measures.
NOTICE：
This is a product for restricted sales distribution to informed partners. Installation restrictions or
additional measures may be needed to prevent radio interference.

DO NOT CONNECT equipment that could overload the UPS or demand DC current from the
UPS, for example: electric drills, vacuum cleaners, laser printers, hair dryer or any appliance using
half-wave rectification.
Storing magnetic media on top of the UPS may result in data loss or corruption.
Turn off and isolate the UPS before cleaning it. Use only a soft cloth, never liquid or aerosol
cleaners
2. Introduction
Congratulations on your choice of the uninterruptible power system(UPS), the UPS comes in
nominal power ratings of 1000VA,2000VA and 3000VA. It is designed to provide conditioned
power to microcomputers and other sensitive electronic equipment.
When it is generated, alternating current is clean and stable. However, during transmission and
distribution it may be subject to voltage sags, spikes and complete power failure that may interrupt
computer operations, cause data loss and even damage equipment. The UPS protects equipment
from these disturbances.
The UPS is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its
output voltage, whether utility power is present or not. It supplies connected equipment with clean
sinewave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the UPS features a LCD display to indicate all information for UPS, and provide
kinds of function buttons.
