POWERGUIDELINES

POWERDISSIPATIONANDCURRENTREQUIREMENTS

Properdesignofthepowerdistributionsystemisessentialforreliable,long‐termoperationoftheEndurasystem.

Giventhemultitudeofactivedatabasetransactionsandfileoperationsthatsymbolizevideosurveillancesystems,

thereliabilityofthepowersupplyisacrucialelementinpreventingfileanddatabasecorruptionissues.When

designingtheelectricaldistributionsystem,considerthefollowing:

•Totalpowerbudgetrequiredforallequipmentatagivennode

•CircuitbreakerorUPSstrategythatincorporatesin‐rushandstart‐upcurrentloads

•Provideextraloadprojectedgrowthofthesystem

•Providecontinuousandreliablepowerunderallexpectedoperatingconditions

TableAprovidespowerdissipationandstart‐upcurrentrequirementsforEnduraequipment.Consultapplicable

regulationsandstandardsfordeterminingtheproperwiregaugetouse.Generally,youshouldinstallcircuit

POWERQUALITY

AswithanyITequipment,Enduracomponentsrelyonproperinstallationpracticestominimizepowersurgesand

otherfluctuationswiththepowersupply.UnlikeITequipment,Enduracomponentsusecustomdesignedpower

suppliesthatmeetEN50130‐4standardforalarmmonitoringequipment.Thisallowsthecomponenttowithstand

afive‐cycledipinpowersupplywithoutresetting.Evenwiththeseprecautionsincorporatedintothedesign,

powerfluctuationscanstilladverselyaffecttheequipmentandshouldbeavoided.

Powerqualitycanbemeasuredusingapowerqualityanalyzer.Thefollowinglistdescribesthecommonissuesthat

mustbemitigatedtoprotectyoursystemandequipment.Theequipmentproblemsassociatedwiththese

anomaliesrangefromvideodistortionandun‐intendedincreasesinbit‐ratestodamagedelectroniccomponents.

•Frequency:Variationofthepowerwaveform

•Harmonicdistortion:Multiplesofpowerfrequencysuperimposedonthepowerwaveform

•Linenoise:Distortionssuperimposedonthepowerwaveform

•Overvoltage:Increasedvoltagesforanextendedperiodoftime

•Powerfailure:Totallossofutilitypower

•Powersag:Shorttermunder‐voltage

•Powersurge(spike):Quickburstofovervoltage

•Switchingtransient:Under‐voltageorovervoltageforuptoafewnanoseconds

•Under‐voltage(brownout):Lowlinevoltagesforanextendedperiodoftime

NOTE:Iftheseissuesaresuspectedorknowntooccurforagivensite,ensurethatproperstepshavebeentaken

toisolatetheequipmentfromtheseanomaliespriortoturningontheEnduraequipment.



RECOMMENDEDPROTECTIONPRACTICES

TheEndurasystemcanbeprotectedfrommanysourcesofelectricaldisturbancesbyadheringtothefollowingthe

recommendations.Pleasenotethatitisbeyondthescopeofthisdocumenttoprovideexplicitinstructionsfor

electricaldistributionsystemdesignandconfiguration.Ifindoubt,pleaseconsultwithalicensedelectrical

contractor.

•Dedicateapowerdistributionsystemforthevideosurveillanceequipment

•Minimizetheuseofhigh‐currentdrawdevicessuchasheating,ventilation,andairconditioning(HVAC)

unitsplacedontheEndurapowerdistributionnetwork,asthesecancauseadiporinterruptionwhenthe

equipmentturnson

•DonotconnecttheEndurasystemtocircuitswithinductiveloads(forexampleHVAC,motors,andso

forth)

•Wherepossible,usepowerconditioningequipment(lineconditioner)thatsmoothesoutpeaksanddips

onthepowernetwork

•Wherepossible,useover‐andunder‐voltagedetectionandprotectioncircuits

•Installlightningarresters(surgeprotectors/suppressors)onpowercordstoprotectequipmentagainst

electricalstorms

•UseUPSsystemsand,asappropriate,abackupgenerator



UNINTERRUPTIBLEPOWERSUPPLYGUIDELINES

Installinganuninterruptiblepowersupply(UPS)ishighlyrecommendedforanyrecordingdevicetoensurethat

poweriscontinuouslyandconsistentlydeliveredtotheEnduracomponent.AUPSistypicallyratedbythePractical

PowerRange,expressedinkVA.Theequivalentwattratingisroughly60to90percentoftheVArating,depending

ontheefficiencyoftheUPS.WhenselectingaUPS,usethepowerandcurrentrequirementspresentedinTableA

asaguideline.ThefollowingexampledescribeshowtocalculatetheUPSsizerequiredforaninstallationwithtwo

NSM5200sconnectedtothesameUPS:

Example:TwoNSM5200saretobeconnectedtothesameUPS.FromTableA,eachNSM5200dissipates262Wof

powerandhasastart‐upcurrentof6Aperpowersupplymodule.

Step1:Calculatethetotalpowerinwattsrequired:

262Wx2=524W

Step2:ConvertthewattagetoVAbydividingby0.60

524W/0.6=873VA–NeedaUPSratedformorethan873VA

Step3:FindtheappropriateUPS:

ConsidertheAPCSmart‐UPS1000VAwithratedoutputpowerof800W/1000VA

NOTE:NSM5200sandDAS5200scomewithredundantpowersupplies.Eachsupplyfortheunitshouldbe

connectedtoadifferentcircuittoensurethattheunitdoesnotlosepoweronintheeventofacircuitfailure.

GROUNDING

Aproperlygroundedinstallationiscriticalinensuringthefault‐freeoperationofEnduraequipment.Allconduit

usedshouldbesecurelyconnectedrigidmetal.Anearth‐groundconnectionshouldbemadebyoneofthe

followingmeans:

•Groundingrod

•Buildingsteel

•Conductivecoldwaterservicepipe

Allpowerpanelsshouldbegroundedtotheelectricalserviceentrance.Thegroundconnectionsthatwillbeused

throughouttheserverroomshouldbetestedtoensurealowresistancepathtoground.

NOTE:Besuretoverifythatthereisnodirectcurrent(DC)potentialbetweengroundsofdifferentcircuitsineach

rack.Anyreadingabove1Vmeasuredbetweengroundsshouldbeconsideredaproblemandinvestigated.



GroundingGuidelines

•Mainbuildingelectricalground:Themainelectricalserviceentranceequipmentshouldhaveanearth‐

groundconnectionasrequiredbyapplicablecodes.Connectionssuchasgroundingrod,buildingsteel,or

aconductive‐typecoldwaterservicepipeprovideanearth‐ground.

•Electricalconduitground:Allelectricalconduitsshouldbemadeofrigidmetallicconduitthatissecurely

connectedtogetherorbondedtopanelsandelectricalboxestoprovideacontinuousgroundingsystem.

•Powerpanelground:Eachpowerpanelshouldbegroundedtotheelectricalserviceentrancewithgreen

(green/yellow)wiregroundconductors.Thegreen(green/yellow)wiregroundconductorsshouldbe

sizedperapplicablecodes.

ELECTROSTATICDISCHARGEPREVENTION

Electrostaticdischarge(ESD)occurswhenobjectsareseparatedorrubbedtogether.Thevoltagelevelofastatic

chargeisdeterminedbythefollowingfactors:

•Typeofmaterials

•Relativehumidity

•Rateofchangeorseparation

RefertoTableBforsampledataontheeffectofhumidityonchargelevels.



SITECLEANLINESS

Itiscriticalthattheinstallationsitebecompletelycleananddevoidofdustanddebriscreatedduringthe

constructionprocess.Operationoftheequipmentshouldnotbegin(evenfortestingpurposes)untilall

constructionhasbeencompleted.

WARNING:DonotturnontheEndurasystemuntilallconstructioniscompleteandtheinstallationsite

isoperatingatthespecifiedoperatingtemperature.Unitsfunctioningunderhighoperating

temperaturescanexperiencedegradedperformanceandlifeexpectancy.



C2670M‐C  Page10

OPERATINGTEMPERATURE

Operatingtemperaturehasasignificantimpactonthemeantimebetweenfailures(MTBF)ofharddiskdrivesand

othersensitiveelectroniccomponents.Variouspublishedfindingsindicatethataharddiskdriveexposedtoa

temperatureextremeissusceptibletoearlyfailure.Generally,forevery18°Fincrease(aboveroomtemperature)

inoperatingtemperature,thelifeexpectancyoftheharddrivedecreasesby35percent.Forexample,aharddrive

operatingat115°Fwouldsuffera58percentreductioninlongevity.Similarly,batterybackupinaUPSoperatingat

77°F(25°C)hasanaveragelifeexpectancyof3to5years.Thisdramaticallydropsto1.5yearsiftheUPSis

operatedat104°F(40°C).WhileEnduraequipmenthasaspecifiedrange,thebestperformanceandlongevityis

attainedwhentheoperatingtemperatureismaintainedatorunder77°F(25°C).

ForthepurposesofEnduraequipment,thespecifiedoperatingtemperatureistheactualtemperaturedirectlyin

frontofthebezelofthechassis.Pelcoproductshaveundergoneanextensiveamountofdesignandengineering

tokeeptheoperatingtemperatureofinternalcomponentsasclosetotheambienttemperatureoftheroomas

possible.Assuch,maintainingtherightambienttemperatureatthefrontoftheunitiscritical.Therack‐

mountableEnduraserversuseactivecoolingbydrawingairinfromthefronttotheback.Themostsensitive

componentsaretypicallymountedatthefrontoftheunittotakeadvantageofcoolerambientairtemperatures.

Properrackdesignandtemperaturecontrolarecriticalcomponentsforsystemstabilityandhealth.

WheninstallinganEndurasystem,followthesegeneralguidelines:

•Ensureproperambienttemperatureisalwaysmaintainedintherackroom

•Ensurethattheambienttemperatureatthefrontofeachunitiswithintheoperatingspecificationrange

•Ensureproperheatexhaustinthebackoftherack

•Ifmultiplecomponentsareplacedinthesamerack,ensurethatnoheattrapsexistintherack(whena

deepercomponentisplaceddirectlyaboveashortercomponent,theextradepthofoneunitcreatesa

heatpocketthatcantraptheheatgeneratedandexhaustedbytheshorterunit)
