2. INTRODUCTION
Congratulations on your choice of the ZY120 uninterruptible power system (UPS), the UPS
comes in nominal power ratings of 6000VA,10000VA and 20000VA. 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.
