1.General information
Beforeyou startwiththeinstallationandthestartingupof theinverter,pleaseread this manual carefully
andpay special attentiontothenotes and suggestions.
This manualmust bemadeavailable toeveryuser.Beforeworkingwiththe unittheuser must become
familiarwith it.This specially appliestothe knowledgeand observanceof the following safety and
warningindications.
Used symbols:
Danger,warning
Thissymbolis usedwhenthelifeorhealthoftheuserisindangeroraconsiderable damagetoproperty
can occur.
Attention, essential measure
This symbol is shownon placesofthe manual, whicharetobeparticularlyconsidered for safeand
disturbance-free operationof the inverter.
2.Safetyinstructions
Allinstructionsstated in this chapter are important forthesecurity ofusers and machines orsystems
andshould absolutely beconsidered.
2.1.Generalsafety instructions
Invertersworkwithhigh voltages,whichcancausedeathorseriousinjurybytouchingthem. Depending
on thedegree of protectionofthe inverter, inoperationthey may have live, uninsulated andpossibly
alsomovingorrotatingparts,aswellashotsurfaces.Incaseofaninadmissibleremoval oftherequired
covers,an improperuse anda wronginstallationor operation,thereisa danger of seriouspersonal
injuryand damage toproperty.
All operations servingtransport,installation andcommissioning as well asmaintenance are to be
carriedoutbyskilledtechnicalpersonnel(observeIEC 364orCENELECHD384and nationalaccident
prevention rules!).Forthe purposesofthese basic safetyinstructions,"skilledtechnical personnel"
meanspersons who arefamiliar with theinstallation,mounting, commissioning and operationof the
productandhavethequalificationsneededforthe performance oftheirfunctions.
2.2.Intended use
The applicationof theinverterdescribedin this operating manualexclusivelyserves forthe purpose
ofcontinuously variable speed controlofthree-phase motors.
Invertersarecomponentsdesigned tobeusedinelectricalinstallationsormachinery.
Commissioningofthe inverter(e.g.the startingof normaloperation) isprohibited until the systemhas
been provedto conform to theprovisions ofthedirective89/392/EEC(Machinery Safety Directive -
MSD)andthe 89/336/EEC (EMC directive).
The invertermeetsthe requirementsofthe low-voltagedirective73/231/EEC. Theyare subject tothe
harmonizedstandardsoftheseriesEN50178.
The operatorof thesystemis solelyliable fordamage resultingfromimproper use oftheinverter.

2.3.Transport, storage,installation
The invertermustbe protectedagainst inadmissible mechanical loads.Nocomponentsmust be
bentand no insulatingdistances mustbe altered duringtransportation or handling. The inverters
are containingelectrostaticsensitive components which are liabletodamage through improper
use.Do nottouch electroniccomponents andelectricalcontacts. Donot switchoninverters with
mechanicaldamaged electrical orelectronic components,the accordancewiththe applied directi-
vesis nolongerguaranteedinthiscase.With theinstallationofthe inverter attentionis tobepaid
to the prescribed minimum distancesaswellas toasufficientcooling.Theclimatic conditionsshall
be in conformity withEN 50178.
2.4.Electrical connection
Before performing anyinstallationworkthe system mustbe insulatedfrom themains supplyand
protected accordingly.
Afterswitchingoff the linevoltage, wait for atleast5minutes until the DC-link capacitors are
discharged. Onlythen itis allowed toworkonthedevice. Incaseofmalfunctions, the discharge
time could be exceeded substantially.
Becauseofapossibleleakagecurrent>3.5mAfromtheinstalledEMC-filter,the inverterisdesigned
only forpermanentconnection.For sizeandlayoutoftheGND(earth)conductor also see EN
50178.
The invertersare designed to beinstalled in a switchgear cabinet and may onlyoperate when
connected with earth-potential.
Foratrouble-freeoperationoftheinverter,the installation requirements and notes in this manual
are to beconsidered.
Whenusingresidual-current-operatedcircuit-breakerspay attention tothe compatibilitywiththe
inverter.Depending on thetypeofthedevicethe following rules apply:
•Single-phase inverters:pulse-currentsensitive(typeA) or all-currentsensitive(type B)residual-
current-operated circuit-breakers are admissible.
•Three-phase inverters:onlyall-current sensitive (type B) residual-current-operated circuit-brea-
kers are admissible.
Otherwiseanotherprotective measure such as separationfrom the environment by double or
reinforcedinsulation,disconnection from the mainsorsimilararetobeused(EN50178). Thetrigger
currentoftheresidual-current-operated circuit-breakers mustbesufficientlydimensioned since
capacitive leakage currents (cable screens, filters)can easilylead to falsetriggering.
2.5.Operating instructions
The invertercanbe configured to restartautomaticallyincaseofan error.If necessary, thesystem
mustbeequippedwithadditionalmonitoring or protective featurestoavoidresulting dangers(see
accident prevention rules etc.).
The motorcan be stoppedby switching off thesetpointordeactivating theenable input. Ifrequired
forsafetyreasons,aninadvertent restartcanbepreventeddisconnectingtheinverter from the
mains supply.

12.Installation
12.1.Installation
The frequencyinverters aredesigned for installation inaswitchgearcabinet and for
permanentconnection.
The inverter must be installedso that the heat sinkis facing to theright.Onlyin this waysufficient
cooling is guaranteed.
Ifthe inverterhas to beinstalledin adifferent position, externalcooling is required forfull capacity
utilization.
BERGES invertersare generallydesignedsothattheycan be operatedat ambient temperatures
from −5 °C to +45 °C and atarelative humidityof up to 90%.
Formation of condensationmust beavoided!
Please contactBERGES ifthe above values areexceeded. Aheat build-upatthe inverter during
operation mustbe prevented.Theinternal air circulation maypossibly be insufficient if theunit is
installed in a control cabinet with a small volume.
The units should never be installedintheproximityof corrosiveor flammablegases, conductive
dustorlarge magnetic and electric fields.
The inverter should be installed in alocationthat is largely freeofdust,steam and vibrations.
Operationofthe unitsinthepresenceof abrasivedust,steam, condensate, oil mist or aircontaining
saltwillreducetheirusefullife.
Paycloseattentionduringinstallationtoensuringthatnoobjects(such asdrilling swarf,wireor
anythingelse)fallintotheunit.Otherwise adevicefault cannot beexcluded, even after longer
periods of operation.
12.2.Mainspower connection

12.3.Motor connection
Connectthe motorcable tothe U, V, W and PE terminals.
The inverter willbedeactivated in theevent of ashort circuitat the terminals U, V, W.
We recommendPTCevaluation using commercially availabledevices toachieveeffective protection
of the motor.
Ifinterruptingcontacts(e.g. contactorsormotorprotectionswitchesetc.) haveto be installedbetween
themotorandinverter,thecircuitmustbeconfiguredsoastoensurethatthe ENABLE signal(terminals
10/11) isdeactivated beforeseparationofthe inverter/motor connection.A relay switching time of
approx. 30ms suffices.
Longmotor cables(>20m) in connection with high voltage peakscausedby thefast switching output
stages oftheinvertermay endangerthe motorinsulation.Insuch cases werecommend tousesuitable
filtermeasures (e.g.motor chokesor dU/dt filters) toprotect themotor.
12.4.Interferencesuppression measures / EMC
(electromagneticcompatibility)
12.4.1.Generalinformation
Invertersare electronic deviceswhich areused in industrialand commercialsystems. In accordance
withthe EMC-directives89/336/EECthe invertersarenotdesignedfor independentoperation.Thus
invertersshould beusedforfurtherprocessingthroughcompetent machine/systemmanufacturers.
Bythis,the devices donot require a CE-marking. Theproofofthe conformityofthe machine/system
with the required EMC-directives must be furnished by themanufacturer or operator ofthesystem.
The invertersofthe ACM series areequipped withan internal filter and designed to be used in class
"A"environments(firstenvironment,restricteddistribution)accordingtotheproduct standard EN
61800-3.
The evaluationofthe conformitytook place inapracticalstructurehavingtaken into accountthe
following installationnotes.
Voltage peaks producedbyotherdevicesconnected atthemains supplycan possibly disturb or even
damage the inverter.Inputchokes(option)can be usedtoprotect the inverteragainst these voltage
peaks (causede.g.byswitching offof highloadsfrom themains).
12.4.2.Installation notes
Duringoperation, electrical/electronicdevices caninfluence ordisturbeachother via powersupply or
othermetallic connections.
The electromagnetic compatibilityof thesystemis highly influenced bythe manner of the installation.
Measuresforthegrounding,shieldingand filteringaretobeparticularlyconsidered. Bypayingattention
tothefollowinginstallationnotesitcan beassumed that the EMC limit values for thesystem/machine
are kept.
•Invertersand optional components likeinput oroutputchokes mustbe inmetal-to-metal contact
withthegrounded mounting plateusing the wholesurface ifpossible. Usepreferablygalvanized
mounting plates. Painted mounting surfacesmustbe free from paint.
•Laythemains, motor andcontrol cablesin large distance from each other.
•Useshieldedmotorcablesconnectedtoearth onboth sides.
•Connect themotor cable shieldwiththePE terminallocatedinthe terminalbox ofthe motor. Use
possibly metalliccableglands.
•Optionaloutputchokesmust bemounted closeto the inverterand connectedwith shielded cables.
Connect thecableshield toearth on both sides.
•Useshieldedcontrol cablesconnectedtoearth on both sides.
•Unshielded control cables must be twisted.
•Connectthecableshieldseitherwith themounting plate using groundclampsandcontacted over
as large an area oratan equipotential bar(see picture).
•Useacentral earthing point for thewholemachine/system (mounting plate).Connect this pointto
earth usingearth cables witha large crosssection or flat copperbraids.
Remove any paint or varnish!

•Do not extend the shields with single wiresand do notinterrupt themif possible.
•Whenconstructingthe switchgearcabinetorthesystem,separatethepower sectionfrom the
controlsection. Eventuallyprovide a shieldbetween power and control section.
•Wireinductiveswitchingelements (coilsof contactorsorrelays)withRC-elements,free-wheeling
diodes or varistors.
12.5.Mainsback-up fuses
External upstream fusesare requiredtoprotectthecablesandthe unititself. Thefuses mustbe
dimensionedso asto permitstarting up andnormaloperationofmotors.To guarantee this,we
recommendthe useofthe followingsslow-blow fuses:

12.6.Ventilation
Forall inverters,thepermissibleambient temperatureof 45°Cmustnotbeexceeded. This
particularly appliesifthe inverter isinstalledin acontrol cabinet,because operationoftheinverter
mayincreasethe ambienttemperature substantially.Appropriatemeasures, e.g.installationofa
fan,mustbe taken if thepermissibleambienttemperature isalmost reached or exceeded under
full loading of theinverter.
