Step 3. Measure the DC bus potential with a voltmeter while standing on a
non-conductive surface and wearing insulated gloves (1000 V).
Measure the DC bus potential at the test points on the Power Module
Interface board. See figure 9.1 for B-frame drives, figure 9.2 for C-frame
drives, or figure 9.3 for D-frame drives. For additional wiring information, refer
to Appendix C, Appendix D, or Appendix E.
Step 4. Once the drive has been serviced, reapply input power.
