5. Complete the conductivity test between the left and right power structures as
indicated in Table I below.
Important: If the drive fails any of these measurements, verify that you have
properly connected the bus bar kit using the correct terminals.
6. Complete the conductivity test on the DC bus as indicated in Table J below.
Important: If the drive fails any of these measurements, refer to the
Hardware Service Manual for PowerFlex 700S and 700H Drives
(Frame 12), publication PFLEX-TG004…, for troubleshooting
information.
7. Complete the conductivity test on the DC bus to drive chassis ground as
