2. Description of commonly used symbols
Some or all of the following symbols may be used in this manual. It is advisable to
familiarise yourself with them and understand their meaning:
3. Introduction
This Online-Series is an uninterruptible power supply incorporating
double-converter technology. It provides perfect protection specifically for
sensitive IT equipment.
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 intended to purchase by performing a visual inspection of the Model
No. on the rear panel of the UPS.
