Commissioning 4-13
7000 “A” Frame 7000A-RM001A-EN-P – January 2011
PowerFlex 7000 “A” and “B” Frame Drive Commissioning Check List
A commissioning check list has been provided as a quick reference to assist in starting up the drive
system. 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 7000
“A” or “B” Frame user manual for detailed commissioning instructions or contact either the local
Rockwell Automation office or Medium Voltage Support directly for assistance if necessary.
Study Rockwell Automation prints provided with the 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
Drive Application
Review
Inspect the process for hazards. Verify that the load is not turning due to
process (A freewheeling motor will generate voltage).
Lock out and tag all sources of power as per OSHA guidelines
Test for voltage potential in the 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)
Safety Tests
Check fuse and O/L values and compare them to the values specified on
the schematic diagrams.
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 diagrams.
Control wiring routing has been examined to ensure that AC, DC and fiber
optic wiring are separated from each other.
All additional controls 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).
Installation Review
Verify that fan hood has been assembled and mounted properly.
