VFD Panel Commissioning

The document summarizes the commissioning process for a VFD panel, including general checks of the panel components and wiring, insulation resistance testing, motor information collection, functional tests after charging the panel, no-load and load motor experiments, and sign off. Key steps include verifying wiring and connections, performing insulation resistance tests, collecting motor data, running the drive through ID and no-load runs, checking control logic and signals, and recording motor performance data under no-load and load conditions.

any) at all KWH/MFM/Relays.
6 Check the delivery of the rated control voltage OK NOT OK
according to the drawing.
7 Check that the relays, KWH meters, and control OK NOT OK
equipment have the proper rated Aux voltage.
8 Make sure that the control and power circuits OK NOT OK
have fuses with the appropriate ratings.
9 Check that all feeders' inter-panel and OK NOT OK
marshalling wiring is done in accordance with the
drawing.
10 Before charging, make sure that all control fuses OK NOT OK
and future interlock links have been removed.
11 Before the VFD Panel is charged for the first time, OK NOT OK
make sure the feeder door is closed.
12 Check for any damage caused by transportation OK NOT OK
or erection. (List all damaged goods).
13 Prior to charging the panel, make sure it has OK NOT OK
been well cleaned inside.
