Danger
During operation, nevershortthepositiveand negativepoles of theDC distributionunit of the
power systemor thenon-groundingpole and the earth.The power systemisaconstant-voltage
DC power device,shortcircuitwillresultin equipment burningand endanger human safety.
Checkthe polarityof the cableandconnection terminal whenperformingDCliveoperations.
As the operationspace inthe DC distributionunitis very tight,pleasecarefullyselectthe operationspace.
Never wear a watch, bracelet,bangle,ring, or otherconductive objects duringoperation.
Useinsulated tools.
In live operation,keepthe arm,wristand hand tense,sothat when the tool inoperationslips,the movementof
the humanbodyand tool is reducedto a minimum.
Battery
Danger
Danger
Beforeany operationon battery, readcarefully thesafety precautions forbattery transportationand
the correctbattery connectionmethod.
Note
If the pow er systemdoes not connectwithmains power for alongtime, to prevent battery
over-discharge, users should cut batteries off fromthepow er systemthoroughly, for example, pulling
out battery fuses orswitchingoffbattery MCBs.Before puttingthe power systemintooperation,insert
all thebattery fuses or switchonallthe battery MCBs.
Non-standardoperationon thebattery willcausedanger.In operation,precautions shouldbe takento prevent
batteryshort circuit and overflow of electrolyte. The overflow of electrolyte will erode themetal objects and PCBs,
thus causing equipmentdamage andshortcircuitofPCBs.
Before anyoperationonbattery, pay attentionto the followingpoints:
1. Removethe watch, bracelet,bangle,ring,and othermetalobjects onthe wrist.
2. Use specialized insulated tools.
3. Useeye protectiondevice, and take preventive measures.
4.Wear rubbergloves and apronto guardagainstelectrolyteoverflow.
5. In battery transportation,theelectrodeof the battery shouldalways be keptfacing upward.Never put the
battery upside downorslanted.
LLVD And BLVD
The powersystem has batterylowvoltage disconnection(BLVD)function and loadlowvoltage disconnection
(LLVD) function. LLVD means thatthe mains failandbatteries supplypower, the controllercuts the non-priority
loadoff whenthe battery voltage drops downto below44V. In this way, the battery remainingcapacitycan
sustainthepriorityload longer.BLVD means thatthecontrollercuts the loadoff whenthe battery voltage drops
downto 43.2V to prevent over-discharge.
The factory settingis enablingLLVD and BLVD, whichmeans thatif poweroutagelasts fora longtimeor the
powersystem fails,theremightbeLLVD andBLVD. Users shouldclassifytheloads and connectthe non-
priorityloads to LLVD routes,and connectthe priorityloads to BLVD routes.For vital loads,users can disable
BLVD of these loads toinsure reliabilityof the powersupply.
The method of disabling BLVDis:
1. Hardwaredisabling:unplugthesignalcable inJ10interfaceof the controller.Tag the BLVD-disabled label.
The positionofthe controllerand the interface descriptionaregivenin 2.4.2 ConnectingSignal Cables.
2. Software disabling:set‘BLVD Enable’item of the controllerto ‘N’.

Note
The advantageof enabling BLVDis protectingthebatteries fromover-dischargewhenthebattery
voltageis low.Thedisadvantageof enabling BLVDis that w henthebattery voltagedrops downtoa
certainvalue,all the loads (including non-priority loads and priority loads) willbecutoff dueto battery
disconnection.
The advantageof softwaredisablingBLVDis prolonging the powersupplyof priority loads.The
disadvantage is that softwaredisablingcannotpreventunwantedpowerfailure duetomisoperation or
power systemfailure.
The advantageof hardwaredisablingBLVDispreventingunwantedpowerfailureduetomisoperation
or pow er systemfailure,andensuringthe continuity of vital loads’pow er supply.

1.4 Operating Principle
The AC mains comesoutfrom theAC distributionunitand is distributed toeachrectifier.After rectification,the -48V
DC currentfrom eachrectifier flows to the DC distributionunit through busbar,andthenmultipleoutputs ofthe DC
distributionunitprovide power for communicationequipment.Normally,the system operates inparallel floatcharge
state, that is,the rectifiers,load and batteries workin parallel;besides poweringthe communicationequipment,the
rectifiers provide float charge for the batteries.In case of mains failure,the rectifiers will stop working,and the
batteries begintosupplypowerto communicationequipment.WhentheAC mains recovers,the rectifiers will resume
supplyingpowertocommunicationequipmentand chargingthebatteries.
Using centralizedmonitoring mode,the controllermodule manages theAC distributionunitandDCdistributionunit.It
also receives theoperatingdata of the rectifiers andcontrols them accordinglythrough CAN mode.The controllercan
be connected to a localcomputerusing theRS232 port. The powersystem canbe connected to the monitoring
center throughconnectingamodem orothertransmissionresources(suchas PSTNandso on)to achieve remote
monitoring.
For the detailedschematicdiagram ofthe powersystem,seeAppendix5 SchematicDiagram.

better.
The powersystem has lighting protectionatDC side,whichcanmeetYD/T5098 requirements.There’s noneed to
designlightingprotectionatDCside.
1.5.2 LLVD And BLVD
In case of mains failure,therectifiers willstopworkingandthe batteries willbegin todischarge andpowerthe load.
When the battery voltage falls to the lowvoltage alarm point45.0V (adjustable),thesystem willgive audible/visual
alarm.Whenthe battery voltage continues to fall and reaches theLLVD point44.0V (adjustable),theLLVD contactor
willopen,cutting off the powersupplyfor the non-priorityloads connected tothe LLVD output branches thus the
powersupplyto priority loadcan be prolonged.As the batteries discharge,the battery voltage continues tofall. When
it reaches theBLVD point43.2V (adjustable),theBLVD contactor willopen,and the battery dischargewill com etoan
end. Thus the powersupplyto all loads is stopped,protectingthebattery from being damaged duetoover-discharge.
When the mains recovers andtherectifier outputresumes normalfunctioning,theLLVD andBLVD contactors will
automaticallyclose,andthesystem willresumenormaloperation.
1.5.3 Fault Alarm And Protection
The powersystem provides perfect fault alarm and protection functions.The system operating datacan be collected
and the states of the loadMCBs, load fuses,batteryfuses andLevel2 (class C)SPD can be detected by the
controller.The alarm level can be setand audible/visualalarmscanbeselected forthe system alarms,suchas AC
inputover/under voltage, DC output over/under voltage, fuse alarm,float charge and equalized charge status,rectifier
fault andprotectionalarm.The alarm type canbe configuredto correspond todrycontact relay output.
