Setup Range Description
3P4U (default) 3-phase 4-wire (3P4W)
3P3U 3-phase 3-wire (3P3W)
1P3U Single-phase 3-wire (1P3W)
1P2U Single-phase 2-wire (1P2W)

3-phase 3-wire Open-Delta (3P3O)
1. 「 3P3O 」 is the setup menu for old Accura 2300S models that do not support the 3P3W connection mode. Thus,
even if the connection mode is set to 3P3O, it works in the same way as the 3P3W connection mode.
PT Rating
The ratio of primary to secondary line-to-line voltages is used as the conversion ratio for the primary
voltage. Regardless of the voltage connection mode for measurement, the primary and secondary line-
to-line voltage values of the PT should be input all the time.

The primary and secondary line-to-line voltages for each connection mode is configured as follows. In
case of direct connections without using a PT, the same values should be input as the primary and
secondary line-to-line voltage values.
