1.4.2 Commissioning and running
Cutoffallpowersuppliesconnectedtotherectifierunitbeforeterminalwiring,and
wait for at least the time designated on the rectifier unit after disconnecting the
powersupplies.
Highvoltagepresentsinsidetherectifierunitduringrunning.Donotcarryoutany
operationontherectifierunitduringrunningexceptforkeypadsetup.Forproducts
at voltage class of 4 or 6, the control terminals form extra-low voltage circuits.
Therefore,youneedtopreventthecontrolterminalsfromconnectingtoaccessible
terminalsofotherdevices.
Beforeturningonthepowersupply,checkthecableconnectionstatus.
Preventanyonefromdirectlytouchingtheenergizedpartofthecabinetdoor.Pay

DonotopenthecabinetdoorsincehighvoltagepresentsinsidetheGoodrive800
Proseriesproductduringrunning.
Note
Do not switch on or switch off the input power supplies of the rectifier unit
frequently.
If the rectifierunit has been stored for along time without use, perform checking
andcarryoutpilotrunfortherectifierunitbeforeusingitagain.
Close the rectifier unit front cover before running; otherwise, electric shock may
occur.
1.4.3 Maintenance and component replacement
Only trained and qualified professionals are allowed to perform maintenance,
inspection,andcomponentreplacementfortherectifierunit.
Cutoffallpowersuppliesconnectedtotherectifierunit beforeterminalwiring,
andwaitforatleastthetimedesignatedontherectifierunitafterdisconnecting

Note
Usepropertorquetotightenscrews.
Duringmaintenanceandcomponentreplacement,keeptherectifierunitandits
partsandcomponentsawayfromcombustiblematerialsandensuretheyhaveno

Do not carry out insulation voltage-endurance test on the rectifier unit, or
measurethecontrolcircuitsoftherectifierunitwithamegohmmeter.
During maintenance and component replacement, take proper anti-static
measuresontherectifierunitanditsinternalparts.
1.4.4 Disposal
The rectifier unit contains heavy metals. Dispose of a scrap rectifier unit as
industrialwaste.
Dispose of a scrap product separately at an appropriate collection point but not

2.5 Hardware principles
2.5.1 Basic principles
The basic rectifier unit converts 3PH AC voltage into intermediate DC voltage, and the intermediate DC
voltagecansupplythesubsequentinvertermodules.Itcanconnecttooneormultipleinvertermodules.
The basic rectifier unit is equipped with AC reactors to suppress AC voltage and current harmonics. The

thyristorrectifierbridgehasthecontrollabilitycharacteristic,whichcangraduallyboostthebusvoltageby
controlling the thyristor switch-on through the conduction angle. In this way, there is no need to add
additionalprechargecircuit.
The basic rectifier unit mainly consists of input reactor, semi-controlled rectifier bridge, energy storage
capacitorandDCfuse.Figure2-5showsthesimplifiedmaincircuit.
