Install surge suppressors on all inductive circuits located nearthe drive or coupled to the same circuit.Refer to the drive nameplate or to the catalogue for recommended fuses. Fast acting or time delay Class J fuses can be used.28
TerminalsLogic input switchThe logic input switch SW4 assigns the logic input type to either 24 V (source logic) or 0 V (sink logic).Note: When the logic input is configured for sink logic, grounding the input signals can result in unintended activation of drive functions.UNINTENDED EQUIPMENT OPERATIONDANGER• Protect the signal conductors against damage that could result in unintentional conductor grounding.• Follow NFPA 79 and EN 60204 guidelines for proper control circuit grounding practices.Failure to follow these instructions can result in death, serious injury, or equipment damage.Recommended circuit diagrams for source and sink logicSource (Positive) LogicSource (Positive) LogicSW4SourceCommonP2424 VdcInputPLCSW424 VdcOutputFInputOutputFCommonPLCProgrammableControllerDriveProgrammableControllerDriveSink (Negative) LogicSink (Negative) LogicSW4OutputF24 VdcInputPLCSW424 VdcCommonOutputPLCFInputSinkCommonCCProgrammableControllerDriveProgrammableControllerDrive29
