*1: An integrated low-cut power can be set to the energy parameters listed in the table (refer to Section 3.3).
*2: Either the demand power or demand current can be set as a measurement item.

NOTE

When the current is in a state of equilibrium, the three-phase four-wire system (2.5 element) can
measure the following items: LEAD reactive energy, LAG reactive energy, Apparent energy, Reactive
power, Apparent power, Current-1, Current-3, Power factor, Demand current-1, and Demand current-3.
