Preface Introduction This publication provides guidelines for replacing/installing Power Interface Boards and Switch Mode Power Supply Boards in the PowerFlex 700 drive for Frames 7, 8, 9, and 10. All kits include the board, wrist strap and hardware (if required). Description Power Interface Board Kit Catalog No.
Preface Safety Precautions The precautions and general installation requirements provided in the PowerFlex 700 Frame 7-10 Installation Instructions (publication 20B-IN014) and the PowerFlex 700 User Manual (publication 20B-UM002) must be followed in addition to those included here. To avoid an electric shock hazard, ensure that all power has been removed before proceeding. In addition, before servicing, verify that the voltage on the bus capacitors has discharged.
Preface ATTENTION ATTENTION ATTENTION ATTENTION ATTENTION Publication 20B-IN22B-EN-P — December 2009 This assembly contains parts and sub-assemblies that are sensitive to electrostatic discharge. Static control precautions are required when servicing this assembly. Component damage may result if you ignore electrostatic discharge control procedures. If you are not familiar with static control procedures, reference Allen-Bradley Publication 8000-4.5.
Preface Important Initial Steps Read and follow these statements before performing any service on the drive. • • • • • • 8 Read and follow the precautions in Safety Precautions on page 6. Identify components to be replaced using the figures in Component Diagrams on page 9. Remove protective shields only as necessary. Before disconnecting any wire or cable, verify that it is labeled. Also, when removing components, note hardware type and location.
