Electrical connection
AllelectricalconnectionsoftheISD400ProareconguredasM12round
connectors.
TheIP65protectionclassisonlyachievedusingscrewedplugconnectors.
AllelectriccircuitsconnectedtotheISD400Promustbeconguredas
PELVorSELVcircuits(PELV=protectiveextra-lowvoltage,SELV=safety
extra-lowvoltage).
Byusingappropriatecableentriesandwiring,youcanavoidinterference
fromdevicessuchasswitchingpowersupplies,motors,clockeddrives,and
contactors.
• Cablesshouldbelaidasfarawayaspossiblefromcableswithahigh
levelofradiatedemission.Takeadditionalmeasureswherenecessary,
e.g.separationbymeansofscreeningshields.
• Donotlaycablesparalleltoothercables,especiallynottodeviceswith
ahighlevelofradiatedemission,suchasafrequencyconverter.
• Donotlaycablesparalleltoenergycables.
Pleaseobservethefollowingwiringnotes:
• Acorrectandcompletecableshieldingconceptisrequiredfortrouble-
freeoperation.
• Thecableshieldmustbeconnectedatbothendsinthecontrolcabinet
andatthedevice.Thecableshieldofthepre-assembledcableiscon-
nectedtotheknurlednutandthusalsotothedevicehousing.
• Thecableshieldinthecontrolcabinetmustbeconnectedtotheopera-
tinggroundoveralargesurfacearea.
• Appropriatemeasuresmustbetakentopreventequipotentialbonding
currentsowingthroughthecableshield.
• Donotlaycablesparalleltoothercables,especiallynottodeviceswith
ahighlevelofradiatedemission,suchasafrequencyconverter.
