How do you perform a diode static check on the Flex58 drives?

Issue:
How do you perform a diode static check on the Flex58 drives?

Product Line:
Flex58 or ATV58

Environment:
All

Cause:
Checking diodes to see if they are shorted.

Resolution:
Before starting make sure you turn off ALL POWER on the drive.  Wait 15 mins so that the DC bus has time to discharge below 24vdc on PA+ and PC-.
Using a multi-meter with a diode checker , measure between the DC Bus terminals PA/+ to L1-L2-L3 , then reverse the meter leads and read again between PA/+ to L1-L2-L3. In one direction you should read 0.30 to 0.60 and in the reverse direction you should read OL. Repeat this measurement with the blue wire (PC/-) on the J18 connector or on the (PC-) terminal. If "shorted circuit" is read in any of the readings, I recommend repair or replace the drive.
