Issue:
DC Bus voltage measuring on an ATV630 drive.

Product Line :
Altivar Process Drive

Environment:
ATV630

Cause:
Measuring the DC Bus

Resolution:
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
For a 240vac drive, should measure around 340vdc on the DC bus

NOTE: PA/+ and PC/- terminals are used only to measure the DC Bus voltage and are not intented to be
wired for an external use.
