Where:
Vmax = 660V if PT Ratio = 1.0 and Vmax = 144 * PT Ratio if PT Ratio is not 1.0
Imax = 1.2 * CT primary current
Pmax = Imax * Vmax * 3 if wiring configuration is 4L-n
Pmax = Imax * Vmax * 2 if wiring configuration is not 4L-n
NOTE
An attempt to write any values to one or more addresses from 24 to 30 causes reset of all
demands: Maximum Demand, Accumulated Maximum Demand, Maximum Apparent Demand,
Accumulated Apparent Maximum Demand, Ampere Maximum Demand A, Ampere Maximum
Demand B, Ampere Maximum Demand C.
The record of 0 to the addresses 31 or 32 will reset Consumption; the record of 0 to the
addresses 33 or 34 will reset Returned Energy; the record of 0 to the addresses 35, 36, 37 or 38
will reset Reactive Energy.
