3. Introduction

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
