1.4.2 Commissioning and running
Cut off all power supplies connected to the regenerative rectifier before terminal
wiring, and wait for at least the time designated on the rectifier unit after
disconnectingthepowersupplies.
Highvoltagepresentsinsidetheregenerativerectifierduringrunning.Donotcarry
outanyoperationontherectifierunitduringrunningexceptforkeypadsetup.For
products at voltage class of 4 or 6, the control terminals form extra-low voltage
circuits. Therefore, you need to prevent the control terminals from connecting to
accessibleterminalsofotherdevices.
Beforeturningonthepowersupply,checkthecableconnectionstatus.
Preventanyonefromdirectlytouchingtheenergizedpartofthecabinetdoor.Pay

Note
Do not switch on or switch off the input power supplies of regenerative rectifier
frequently.
If the regenerative rectifier has been stored for a long time without use, perform
checkingandcarryoutpilotrunfortheinverterunitbeforeusingitagain.
Closetheregenerativerectifierfrontcoverbeforerunning;otherwise,electricshock

2.5 Hardware principles
2.5.1 Basic principles
The regenerative rectifier, a four-quadrant rectifier system, mainly consists of regenerative rectifier filter
unitandregenerativerectifierunit.Itisusedwiththepre-chargecircuitandcontrolunit.Theregenerative
rectifier unit converts 3PH AC voltage into intermediate DC voltage, and the intermediateDC voltage can
supply the subsequentinverter modules todrive motors. It can also feed the regenerative energy of the
motorbacktothegrid.Oneormultipleinvertermodulescanbeinstalled.
The regenerative rectifier filter unit, which is the filter, is used to suppress input orregenerative current
harmonics.

2.8.2 Breaker
A breaker can effectively prevent the overload of the variable-frequency equipment and break the fault

The breaker should be equipped with an external terminal to controls the opening and closing of the
breaker and a status feedback auxiliary contact!
