PowerFlex 7000 “C” Frame
Drive Commissioning
Checklist
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 “C” Frame
user manual for detailed commissioning instructions or contact either the local
Rockwell Automation office or Medium Voltage Support directly for asistance if
necessary.
Drive Application Review
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
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 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
(Control power must be 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 on
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 in. (76.2 mm) minimum for 4160V]
Verify that all connectors, cables and components are secure
Verify encoder wiring (if supplied with encoder)
Verify that fan hood has been assembled and mounted properly
