3. Introduction
ThisOn-Line-Series is an uninterruptible power supplyincorporating
double-convertertechnology.It provides perfect protection specificallyfor
Novell, WindowsNTand UNIX servers.
The double-converter principle eliminatesall mainspower disturbances. A
rectifierconvertsthe alternating current from the socket outlet to direct
current. Thisdirect current charges the batteries and powers the inverter. On
the basis ofthis DC voltage, the inverter generates asinusoidal AC voltage,
whichpermanentlysupplies the loads.
Computersand peripheryare thus powered entirelybythe mains voltage. In
the event of power failure, the maintenance-free batteriespower the inverter.
This manual coversthe UPSlisted asfollows.Please confirmwhetherit is
the modelyou intend to purchase byperforming avisualinspection of the
Model No. on the rearpanel of the UPS.

It is alsocalled RPO(RemotePowerOff). On LCD display,the mode string
is “EPO”.
Itis a specialstatusinwhich the UPS would shut the output offandalarm.
The UPS could notbe turned offbypressing“OFF” button onthe panel,
onlyafterreleasing EPOstatus by turning off the EPO switch.
6.6 ECO mode(Economymode)
Itis alsocalled high efficiencymode.In ECO mode, on LCDdisplay,the
modesting is “ECO”.
After theUPS is turned on, the powerusedbythe load issupplied fromthe
utilitypower viainternal filter while the utilitypower isin normal range, so
the high efficiencycould be gained in the ECOmode.Once the mains is
loss orabnormal,the UPSwould transfertobatterymodeandthe load is
supplied continuouslybythe battery.
1) Itcould beenabledthrough the LCD setting or the software (Winpower,
etc.).
2) Itisattention that the transfertime ofUPS output fromECOmodeto
batterymode islessthan 10ms.But it is stilltoolong for somesensitive
load.

6.7 Converter mode
In convertermode, on LCD display,the mode string is “CVCF”.
The UPSwould freerun with fixed outputfrequency(50Hz or 60Hz) in
converter mode. Once the mains isloss orabnormal, the UPS would transfer
to batterymode and the load issupplied continuouslybythe battery.
1)It could be enabled through the LCD setting orthe software (Winpower,
etc.).
2)The load should be derating to 70%in converter mode.
6.8 Abnormal mode
In abnormalmode such as Busfault etc., thecorresponding fault stringwould
be shown to indicate the operating mode of the UPS, and the background light
become red.For example “SHOR”would be shown whenthe load or the UPS
output isshort. The LCD displayis shown in the following diagram.

mode or Bypass mode, TwoLoad segments in outputmode,Batterystring in
all modecould be set directlythrough LCD module. The output voltagecould
be set to208V,220V,230V and 240V.The output frequencycould be set to
50Hzand 60Hz.The bypass state could beset toenableand disable. The
operating mode of UPScould be set between the Line mode, ECO mode and
Converter mode. Batterystring could be set toone to night groups. TwoLoad
segments could be set toon and off.
In bypass or no output mode, pressing the “Enter” button on the LCD panel for
more than one second to entersetting mode. The LCD displayis shownin the
following diagram. The string “OPV” indicatesthat the current setting is output
voltage. “230Vac” indicates thecurrent default output voltage is 230Vac.ifyou
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” turnto flickerless, the output volt ischangedto208V;if the
“Select”button is pressed for morethan one second,the next flickering string
“220” appear,theorder of flickering string is 208 –220 –230 –240 –208,
Press“Enter”button to confirm the output volt what you want.
Exit the setting mode toshort touch the “Enter”button; continue settingto
press “Select” button. if no anypressing on the “Select” or “Enter”button
lasting for more than 10 seconds, the setting mode exit automatically.

“LS2” would be presentedcircularly.The onlyonevoltage value could be
selected in “208V”, “220V”, “230V”, “240V”at anytime; The onlyone
frequencyvalue could be selected in “50Hz”, “60Hz”at anytime;Bypass
status could be selected in “000” or “001”(Here000 means Bypass
Disable,001means BypassEnable),The UPSwould turn tobypassmode in
29
several seconds after“BypassEnable”isselected, andturn to no output mode
in several seconds after “BypassDisable” is selected;Operating mode could
be selectedin “UPS”, “ECO”, “CVF”(Here “UPS”meansthe normal inverter
mode,“ECO”meansthe high efficiencymode, and “CVF” means the converter
mode), Themode changewouldbe active onlyafterthe UPSis turned on;
Batterystringcould be selected in “001” to “009”(Here “001”means one group
battery). Load segment 1could be selected in “000” or “001”(Here 000 means
load segment 1off, 001 means load segment 1on); Load segment 2isthe
same asLoad segment 1.
■Hereisaexample for changingtheOperatingmode fromnormalmode to
convertermodethrough 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” afterpressing 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
