On Frame size 1 through 3 the PA+ and PC- terminals are accessible under a sticker between the line and load connections.
On Frame size 4 and 5 the PA+ and PC- terminals are accessible below the line power terminals and to the left of the load terminals.

For a 480vac drive, should measure around 680vdc on the DC bus
