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
Model No. on the rear panel of the UPS.

It is a special status in which the UPS would shut the output off and alarm.
The UPS could not be turned off by pressing “OFF” button on the panel,
only after releasing EPO status by turning off the EPO switch.
6.6 ECO mode (Economy mode)
It is also called high efficiency mode. In ECO mode, on LCD display, the
mode sting is “ECO”.
After the UPS is turned on, the power used by the load is supplied from the
utility power via internal filter while the utility power is in normal range, so
the high efficiency could be gained in the ECO 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) It is attention that the transfer time of UPS output from ECO mode to
battery mode is less than 10ms. But it is still too long for some sensitive
load.
27
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.
28
7. Setting by LCD Module
The output voltage, frequency, Bypass status and operating mode in No output
mode or Bypass mode, Two Load segments in output mode, Battery string in
all mode could be set directly through LCD module. The output voltage could
be set to 208V, 220V, 230V and 240V. The output frequency could be set to
50Hz and 60Hz. The bypass state could be set to enable and disable. The
operating mode of UPS could be set between the Line mode, ECO mode and
Converter mode. Battery string could be set to one to night groups. Two Load
segments could be set to on and off.
In bypass or no output mode, pressing the “Enter” button on the LCD panel for
more than one second to enter setting mode. The LCD display is shown in the
following diagram. The string “OPV” indicates that the current setting is output
voltage. “230Vac” indicates the current default output voltage is 230Vac. if you
want to set output voltage, press the “Enter” button for more than one second,
a flickering string “208” would be shown, if the “Enter” button is pressed again,
the string “208” turn to flickerless, the output volt is changed to 208V; if the
“Select” button is pressed for more than one second, the next flickering string
“220” appear, the order of flickering string is 208 – 220 – 230 – 240 – 208,
Press “Enter” button to confirm the output volt what you want.
Exit the setting mode to short touch the “Enter” button; continue setting to
press “Select” button. if no any pressing on the “Select” or “Enter” button
lasting for more than 10 seconds, the setting mode exit automatically.
The output frequency string “OPF”, Bypass status string ” bYPA”, operating
mode string “MOdE”, Battery string “bSTR”, Load segment string “LS1” and
“LS2” would be presented circularly. The only one voltage value could be
selected in “208V”, “220V”, “230V”, “240V” at any time; The only one
frequency value could be selected in “50Hz”, “60Hz” at any time; Bypass
status could be selected in “000” or “001”(Here 000 means Bypass
Disable,001 means Bypass Enable),The UPS would turn to bypass mode in
29
several seconds after “Bypass Enable” is selected, and turn to no output mode
in several seconds after “Bypass Disable” is selected; Operating mode could
be selected in “UPS”, “ECO”, “CVF”(Here “UPS” means the normal inverter
mode, “ECO” means the high efficiency mode, and “CVF” means the converter
mode), The mode change would be active only after the UPS is turned on;
Battery string could be selected in “001” to “009”(Here “001” means one group
battery). Load segment 1 could be selected in “000” or “001”(Here 000 means
load segment 1 off, 001 means load segment 1 on); Load segment 2 is the
same as Load segment 1.
■ Here is a example for changing the Operating mode from normal mode to
converter mode through the LCD panel.
Step 1: “OPV” after pressing the “Enter” button; Step 2: “OPF” after pressing the “Select” button.
Step 3: “bYPA” after pressing the “Select” button; Step 4: “MOdE” after pressing the “Select” button,
press the “Enter” button to set mode, then “UPS” flickering;
Step 5: “ECO” flickering after pressing the “Select” button; Step 6: “CVF” flickering after pressing the
“Select” button again. Press the “Enter” button to make sure to change the mode. Short touch “Enter”
button to exit setting mode.

11. Communication Port
11.1 RS-232 and USB communication ports
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
35
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
