How should I use the M5 and M8 mounting holes on the DC OUTPUT terminal of the PXB20K-1000/1500?

Select the M5 or M8 mounting hole according to the crimp terminal of the load cable.

For example, use the M8 mounting hole when connecting the optional load cable (HV22-2P3M-M12M8).

For details, refer to "Connecting the DUT" in the User's Manual.
