1. “3P3O” is setup menu for some older Accura 2300 that is not supported for 3P3W voltage connection in Accura 2300 for
3-phase 3-wire voltage connection. It works as 3P3W connection even if it is set to 3P3O connection.
PT Rating
Ratio of primary and secondary line-to-line voltage ratio is used as conversion ratio for primary voltage.
Regardless of voltage connection for measurement, always PT primary and secondary line-to-line voltage
should be input.

Primary and secondary line-to-line voltage for each connection method is as follows. In case of direct
connection without using PT, primary and secondary line-to-line voltage should be input as the same value.
