1INTRODUCTION
This on line series UPS is an uninterruptible power supply incorporating double-conversion
technology and provides perfect pure sine wave output for load specifically designed for Servers.
Adopting the double-conversion principle, this advanced UPS system eliminates all mains power
disturbances. An internal rectifier converts the alternating current to direct current, and then the direct
current will be used for charging the batteries and powering the internal inverter. By converting the
DC voltage, the inverter generates a sinusoidal AC voltage which supplies the load without
interruption. All the peripheral devices are thus powered entirely by the mains power. However, In
the event of power failure, the maintenance-free batteries will power the whole system.
This manual covers the following Models of UPS. Please confirm if the model purchased is included
