6. ELECTRICAL CONNECTIONS
WithintheEuropeanUnion,allmachinesincorporatinganinvertermustconformtothemachinesdirective2006/42/EC.The
machinemanufactureris,inparticular,responsibleforinstallingageneralswitchandensuringcompliancewithstandardEN
60204-1.
6.1 CONNECTION BEST PRACTICE
The following information describes the wiring guidelines and best practices which should be observed when using the inverter.
DANGER
RISK OF ELECTRIC SHOCK, EXPLOSION OR ELECTRIC ARC
• Onlysuitablytrainedpersonnel,familiarwithandcapableofunderstandingthecontentofthemanualandallrelevant
documentation,areauthorisedtoworkonandwiththisinverter.Furthermore,thepersonnelmusthavecompletedcourses
insafetyandmustbeabletorecogniseandpreventtheimplieddangers.Installation,adjustmentandmaintenancemust
only be carried out by qualified personnel.
• Variousproductcomponents,includingtheprintedcircuits,runathazardousvoltagelevels.
• Only use electrically insulated and suitably calibrated measuring devices and equipment.
• Do not handle the equipment while the power supply is connected.
• Do not touch the unshielded components or the terminals while they are live.
• Themotorsmaygeneratevoltageiftheshaftisrotated.Beforecarryingoutanyworkontheinverter,lockthemotorshaft
to prevent it from rotating.
• Beforeworkingontheinverter:
• Disconnect the power supply.
• UseasuitablycalibratedandelectricallyinsulatedVoltmetertomakesurethepowersupplyisdisconnected.
• Waitfor5minutedafterdisconnectingthepowersupplybeforeinstalling/uninstallingaccessories,hardware,cablesor
wires,toallowthecondenserstodischargeanyresidualvoltage.
• Donotopen,disassemble,repairormodifytheproduct.
• Beforehandlingtheproduct,makesureyouarewearingallthenecessarypersonalprotectiveequipment(PPE).
• Do not expose the equipment to liquids or chemicals.
• Before applying voltage to the inverter:
• Makesuretherunningperiodhasbeencompletedandnopartsofthesystemcanbecomehazardous.
• Ifthemainspowersupplyterminalsandthemotoroutputterminalshavebeenearthedandcircuited,removetheearth
and short circuits on these terminals.
• Makesurealltheequipmentisproperlyearthed.
• Makesureallprotectiveelements,suchascovers,hatchesandgrilles,arefittedand/orclosed.
• Checkallwiringconnections.
DANGER
RISK OF ELECTRIC SHOCK, EXPLOSION OR ELECTRIC ARC
Makesurealltheequipmentisproperlyearthed.
DANGER
RISK OF ELECTRIC SHOCK AND FIRE
• Do not use the device with loads greater than those indicated in the technical data section.
• Do not exceed the temperature and humidity ranges indicated in the technical data section.
• Onlyusecableswithasuitablecross-sectionasindicatedinthesection“Wiringbestpractices”.
ForinstallationinaccordancewithstandardEN61800-5-1,adevicecuttingoffthecircuitbetweenthepowersupplyandthe
inverter is required.
DANGER
RISK OF ELECTRIC SHOCK
Usetherequiredsafetyinterlocks(fusesand/ormagnetothermalswitches)ofasuitablesizebetweenthepowersupplyand
the inverter.
Whentheinverterisinstandbyandthemotorisnotrunning,thelatterremainslive.
DANGER

6.1.1 Wiring best practices
Whenwiringthecontrollers,observethefollowinginstructions:
• TheI/Oandcommunicationwiringmustbekeptseparatefromthepowersupplywiring.Thesetwotypesofwiringmust
be routed in separate ducts.
• Makesuretheoperatingenvironmentandconditionsfallwithinthespeciedvalues.
• Usewireswiththecorrectdiameter,suitedtothevoltageandcurrentrequirements.
• Use copper conductors (compulsory).
• Use shielded twisted pair cables for analogue I/O connections.
• UseshieldedtwistedpaircablesfornetworkandRS-485serialconnections.
Usecorrectlyearthedshieldedcablesforallinputsoranalogueoutputs,forcommunicationconnectionsandformotorwiring.
WARNING
MALFUNCTIONING OF THE EQUIPMENT
• Performthewiringcarefully,incompliancewithelectromagneticcompatibilityrequirements.
• Carryoutafullstart-uptest.
• Makesurethewiringiscorrectforthesettings.
• Use shielded cables for all I/O signal and communication cables.
• Usedouble-shieldedcablesformotorwiring.
• Minimisethelengthoftheconnectionsasmuchaspossible,toavoidwindingthecablesaroundelectricallyconnectedparts.
• The signal (communication and corresponding power supplies) and power cables for the device must be routed separately.
• Beforeapplyingthepowersupply,checkallthewiringconnections.
• Donotconnectwirestounusedterminalsand/orterminalsmarkedwiththetext“Noconnection”(N.C.).
