Single-phase and Three-phase Input TypeInstruction Manual1 Method of connectingEMI/EMC Filter2 Caution when connectingEMI/EMC Filter(1) Single-phaseLNFGLN12EMI/EMCFilter34142EMI/EMCFilter536DeviceDevicePlease note the excessive temperature increase of EMI/EMC fi lter.Please contact us if judgement is diffi cult.(1) Input voltage and frequencyPlease use within the rated voltage (or maximum voltage) of eachmodel.Input frequency specification for AC input EMI/EMC filter isconsidered as commercial frequency (50/60Hz).It should not be used under the following conditions.1) Distorted input voltage waveform.(Triangle wave, square wave etc.)2) High input frequency (ex: 400Hz)FG(2) Input currentPlease use within the rated current of each model.¶Three-phase three-wire EMI/EMC filter is also available as aSingle-phase input type.(2) Three-phase three-wireL1L2L3FG142EMI/EMCFilter536DeviceEMI/EMC fi lters have short term peak current capability. Therefore,it can fl ow ~40A or ten times of rated current, non-repeated, within afew ms such as inrush current of power supply etc.However, it should not be used under the following conditions.1) Long duration peak current.2) Peak current or high-frequency current is continuously flowing.(3) Connection to a general-purpose inverter (servo driver)Please connect EMI/EMC filter to input side of inverter driver(servo driver).It should not be used between the inverter (servo driver) and themotor.(3) Three-phase four-wireL114L22EMI/EMC5L33Filter6NNN'FGDeviceEMI/EMCFilterpossibleEMI/EMCFilterpossibleInverterorservo driverInverterorservo driverEMI/EMCFilterSingle-phaseinput typeimpossibleEMI/EMCFilterThree-phaseinput typeimpossibleMotorMotorEMI/EMCFilter[Reference] Example of calculating input current calculationInput voltage 400 [V]Input capacity of the equipment 4000 [VA]4000 [VA]Input current == 5.8 [A]400 [V]X 3(4) Caution when a Three-phase four-wire systemWhen using a Three-phase three-wire system input, deltaconnection cannot be used.When using the N and N' terminals of the EMI/EMC filter, theneutral line (N phase) must be connected.If you have a Three-phase four-wire system with a Single-phaseload connected between the neutral and each line, the neutralmay carry considerably more current than the line current.Manual-1 ? 900 ?
