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
the model you intend to purchase by performing a visual inspection of the

6.7 Converter mode
In converter mode, on LCD display, the mode string is “CVCF”.
The UPS would free run with fixed output frequency (50Hz or 60Hz) in
converter mode. Once the mains is loss or abnormal, the UPS would transfer
to battery mode and the load is supplied continuously by the battery.
1) It could be enabled through the LCD setting or the software (Winpower,
etc.).
2) The load should be derating to 70% in converter mode.
6.8 Abnormal mode
In abnormal mode such as Bus fault etc., the corresponding fault string would
be shown to indicate the operating mode of the UPS, and the background light
become red. For example “SHOR” would be shown when the load or the UPS
output is short. The LCD display is shown in the following diagram.

To establish communication between the UPS and a computer, connect a
computer to one of the UPS communication ports by using an applicable
communication cable.
NOTE:
Only one of the communication ports can be active at one time. The USB port has
priority over the RS-232 port.
When a communication cable is installed, the power management software can
exchange data with the UPS. The software polls the UPS for detailed information
on the status of the power environment. If a power emergency occurs, the
software initiates the saving of all data and an orderly shutdown of the equipment
11.2 RS-232 port
The RS-232 port is available for UPS monitoring, control, and firmware
updates. To establish communication between the UPS and a computer,
connect one end of the serial communication cable that comes with the UPS
to the RS-232 port on the UPS. Connect the other end of the serial cable to
the RS-232 port on a computer.
The cable pins for the RS-232 communication port are identified in the
following illustration.

12. Software Installation
WinPower is UPS monitoring software, featuring user-friendly interface to
monitor and control your UPS. This unique software provides complete
power protection for computer system while power failure. With the
software users can monitor any UPS status on the same LAN.
Furthermore, a UPS can provide security protection for more than one
computer on the same LAN at the same time, such as shutting down
system in security, saving application data and shutting down the UPS
when power fails.
Software Installation on your PC:
Connected by USB to a PC or notebook, the Software enables communication
between the UPS and the computer. The UPS software monitors the status of the
UPS, shuts down the system before the UPS is exhausted and can remotely observe
the UPS via the Network (enabling users to manage their system more effectively).
Upon AC failure or UPS battery low, UPS takes all necessary actions without
intervention from the system administrator. In addition to automatic file saving and
system shut-down functions, it can also send warning messages via pager, e-mail
etc.
• Use the bundled CD and follow the on-screen instructions to install the software
WinPower.
• Enter the following serial No. to install software: 511C1-01220-0100-478DF2A
• After the software is successfully installed, the communication with UPS has
been established and an green icon will appear in the system tray.
• Double-click the icon to use the monitor software (as above).
• You can schedule UPS shutdown/start-up and monitor UPS status through PC.
