3. Introduction – 1000H(XL)/2000H(XL)/3000H(XL)
This On-Line-Series is an uninterruptible power supply incorporating double-converter
technology. It provides perfect protection specifically for Novell, Windows NT and UNIX
servers.
The double-converter principle eliminates all mains power disturbances. A rectifier converts
the alternating current from the socket outlet to direct current. This direct current charges the
batteries and powers the inverter. On the basis of this DC voltage, the inverter generates a
sinusoidal AC voltage, which permanently supplies the loads.
Computers and periphery are thus powered entirely by the mains voltage. In the event of
power failure, the maintenance-free batteries power the inverter.
This manual covers the UPS listed as follows. Please confirm whether it is the model you
intend to purchase by performing a visual inspection of the Model No. on the rear panel of the
