3. Introduction
This On-Line-Series is an uninterruptible power supply in orporating double- onverter te hnology. It provides
perfe t prote tion spe ifi ally for Novell, Windows NT and UNIX servers.
The double- onverter prin iple eliminates all mains power disturban es. A re tifier onverts the alternating
urrent from the so ket outlet to dire t urrent. This dire t urrent harges the batteries and powers the inverter.
On the basis of this DC voltage, the inverter generates a sinusoidal AC voltage, whi h permanently supplies the
loads.
Computers and periphery are thus powered entirely by the mains voltage. In the event of power failure, the
maintenan e-free batteries power the inverter.
This manual overs the UPS listed as follows. Please onfirm whether it is the model you intend to pur hase by
performing a visual inspe tion of the Model No. on the rear panel of the UPS.
