1. INTRODUCTION
This is a high performance with compact shape line interactive Uninterruptible Power Supply (UPS) designed to protect
your computer from utility line failure.
In the event of utility failure (blackout), the UPS will rapidly transfer loads to an alternative power source which derives
power from battery set inside the UPS. The backup time for a Pentium III including 17" SVGA monitor is about 10
minutes with internal UPS model ALPHA 500 inT.
2. MAIN FEATURES
! Microprocessor based design.
! 'Green power' design with auto on/off function.
! Suitable for 5 1/4" disk size.
! Protection for overload & short circuit.
! Easy installation.
3. CAUTION
The UPS is suitable for personal computer & workstation only; and is to be installed inside a computer case.
After installation, please make sure that the maximum power requirement is not over the rated capacity of the
UPS. Red LED will be lighting and alarm will beep if the load is close to the rated value. Meantime, if the
overload is severe, the UPS will shut down immediately when a blackout happens in order to protect itself.
The UPS is shipped from the factory with fully charged internal batteries; however, the batteries may lose some
energy during delivery and storage. To ensure that the UPS will provide the expected run-time, the UPS must be
charged for at least 12 hours before your first use. Please simply turn on the UPS after installation when city
power is normal, and the batteries will be charged automatically.
