Rockwell Automation 7000L PowerFlex Medium Voltage AC Drive (C Frame) - Classic Control - Manual (Page 215)

4-10 Commissioning
7000L-UM300I-EN-P – June 2013 7000 “C” Frame
PowerFlex “C” Frame Commissioning Checklist
A commissioning checklist has been provided in this manual as a quick reference to assist in starting up
the drive line-up. This checklist should not be used as a detailed instruction or in no way includes all
necessary steps to commission every possible drive configuration. Refer to the procedures in the
PowerFlex “C” Frame manual for detailed commissioning instructions or contact either the local
Rockwell Automation office or Medium Voltage Support directly for assistance if necessary.
It is recommended that this checklist be photocopied so as that it is readily available while performing
drive commissioning.
Drive Application
Review
Study Rockwell Automation prints provided with Drives System.
Study the system one-line diagram and identify all sources of power.
Verify one-line diagram. Trace power cables back to their sources and
verify that equipment tag ID numbers agree with the customer‟s one-
line diagram.
Inspect the process for hazards. Verify that the load is not turning due
to process (A freewheeling motor will generate voltage).
Safety Tests
Lock out and tag all sources of power as per OSHA guidelines.
Test for voltage potential in cabinet with appropriate safety equipment.
Remove step down CPT or PT fuses and place them in a safe place
outside of the drive cabinet (To be done with control power off).
Check fuse and O/L values and compare them to the values specified
on the schematic diagrams.
Installation Review
Examine the drive for shipping damage.
Inspect cabinets for debris.
Ensure that protective barriers removed for drive commissioning have
been re-installed.
Verify that the drive line-up and all associated equipment have system
power grounding cable installed.
Power cabling is appropriately rated and stress-coned, if required.
Power cabling has been Hi-potted or Meggered.
Power cabling has been torqued per table in Appendix B.
Control reactor wiring has been correctly installed as shown on the
Rockwell Automation electrical diagram.
Control wiring routing has been examined to ensure that AC, DC and
fiber optic wiring are separated from each other.
All additional control not shown on the prints has been identified,
documented and forwarded to the factory for future reference.
Verify that all low voltage cables in the medium voltage cabinet have
sufficient clearance from power components (3 inch [76.2 mm]
minimum for 4160 V)
Verify that all connectors, cables and components are secure.
Verify tachometer wiring (if supplied with tachometer).
