to be reduced considerably,and inthe worst case,the inverter to be damaged.Please handle the inverter properly in accordance with the information on each section as well as theprecautions and instructions of this manual.Handling PointsRefer To:Use the power supply within the permissible powerPower supplysupply specifications of the inverter.No-fuse breaker or earth leakage circuit breakerThe breaker should be selected with care since a largeNo-fuse breakerinrush current flows in the inverter at power on.(NFB)or earthleakage circuitMagic contactorbreaker (ELB)The magic contactor need not be provided.Whenor Fuseinstalled,do not use it to start or stop the inverter.Itmight cause damage to the inverter.Magic contactoInstalling the reactors(MC)The reactor (option)must be used when the powerfactor is to be improved or the inverter is installed neara large power supply capacity (1000KVA or more andPower factorwiring distance within 10m).improving ACUse either of the following reactors according to thereactorPower factormodel used:(FR-BAL)improving DCPower factor improving DC reactor (FR-BEL)...5.5K toreactor(FR-BEL)55K (200V,400V)(The DC reactor cannot beconnected to any inverters of 3.7K and down.)Power factor improving AC reactor (FR-BAL)...0.4K toPlace of installationThe inverter life is influenced by ambient temperatureInverterUse the inverter at the ambient temperature as low aspossible within the permissible range.This must be noted especially when the inverter isinstalled in a panel.WiringWrong wiring might lead to inverter damage.Thecontrol signal lines must be kept sufficiently away fromp.9-14the main circuit to protect them from noise.Equipment connected to the output sideGroundDo not connect a power capacitor.surge suppressoror radio noise filter (FR-BIF or FR-ALF option)to theinverter output,or damage might result.MotorGroundTo prevent accidental electric shock,the motor andinverter must be grounded.Ground+1.ACCEPTANCE INSPECTIONUnpack and check the following:(1)Check the capacity plate on the inverter front cover and the rating plate on the inverter side face,and ensure that the type and output rating agree with your order.(2)Check for damage in transit.If you have found any discrepancy,damage,etc.,please contact your sales representative.MITSUBISHIINVERTERMODELFR-A220-0.4KP-ULInverter typeFR-A220-3.7K-ULINPUT A 3PH AC200-220V 50HzApplicable3PH AC200-230V 60Hzpower supplyOUTPUT MAX AC200-230VOutput ratingInverter

front cover,hold both sides of the front cover top and pull the cover toward you.(See Fig.2.1.)To reinstall the front cover,fit the sockets at the cover bottom into the catches of the inverter,andsecurely press the cover against the inverter using the catches as supports.(See Fig.2.2.)CatchFig.2.1 Removing the Front CoverFig.2.2 Reinstalling the Front

that the front cover has been reinstalled securely.(2)The same serial number is printed on each of the capacity plate on the front cover and therating plate on the side face.Before reinstalling the front cover,check the serial number toensure that the cover removed is installed to the inverter from which it has been removed.2.STRUCTUREWhen the inverter surface is stained with fingermarks,oil and/or the like,gently wipe that area with asoft cloth soaked with a neutral detergent or ethanol.Note:(1)Do not use any solvent,such as acetone,benzene and toluene,that will cause the invertersurface to dissolve and the paint to peel.Note:(2)Do not clean the lens of the inverter LED with a detergent or alcohol which will easily affectthe lens.2.3 Removal and Reinstallation of the Parameter UnitTo remove the parameter unit,hold down the top button of the parameter unit (using the catch as asupport)and pull the parameter unit toward you as shown in Fig.2-5.To reinstall,fit the fixing hole ofthe parameter unit into the catch of the cover,then push it into the inverter (using the catch as asupport).Note:Do not install the parameter unit when the front cover does not exist on the inverter.When installing the parameter unit,do not apply force to the display(liquid crystal)area.ButtonCatchFixing hole-Fig.2.5 Removing and Reinstalling the Parameter Unit2.4 Removal and Reinstallation of the Accessory CoverAs described in the removal and reinstallation of the parameter unit,to remove the accessory cover,hold down the top and pull the accessory cover toward you.To reinstall,fit the fixing hole into thecatch of the cover and push the cover into the inverter.2.STRUCTURE2.5 Handling of the FR-PU01E Parameter UnitThe FR-PU01E parameter unit can be used by connection to the FR-A series inverter by a cable(option).Note:When the FR-PUO1E parameter unit is used,reset (or power down)the inverter after the unit isconnected.Otherwise the parameter unit will not function.The functions of the FR-A seriesinverter are limited with the FR-PU01E.(Read and write of the parameters Pr.80 to 231cannot be performed.Any attempt to set the above parameters results in Err display.)Thecalibration function parameter numbers 900 to 905 should be set using the third functions C1to C6 of the FR-PU01E.FR-PU01Insert along the guideFig.2.6 Connection of the FR-PU01E Parameter Unit2.6 Handling of the FR-ZRWE Parameter Copy UnitLike the FR-PU01E,the FR-ZRWE parameter unit can be used by connection to the inverter by thecable (option),provided that the functions are limited.In addition,the function of reading and copyinga batch of parameters to another inverter cannot be used.MEMO3.INSTALLATION3.1 TransportationDuring transportation,handle the inverter carefully to protect it from damage.Hold the inverter so as not to apply force only to the front cover of the inverter.3.2 Place of Installation(1)Do not install the inverter where it is subjected to direct sunlight,high temperature,high humidity,oil mist,flammable gases,fluff,dust,dirt,etc.Install the inverter in a clean place or inside a to-tally enclosed panel which does not accept any suspended matter.Note:When the inverter is installed in a panel,determine the cooling method and paneldimensions so that the ambient temperature of the inverter is within the permissible range(as specified on page 102).Extreme care must be taken when two or more inverters are installed and a ventilation fanis mounted in the panel.If the inverters and/or ventilation fan is installed in an improperposition,the ambient temperature will rise and ventilation effect will reduceLike the inverter,protect the parameter unit from direct sunlight,high temperature andhigh humidityBuilt-incooling
