3. Introduction
CNQplus RT serries consist of uninterruptible power supply systems
incorporating double-converter technology. They provide perfect protection
especially 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 peripherals 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 below. Please confirm whether this is the
model you intended to purchase by performing a visual inspection of the
Model No. on the rear panel of the UPS.
