THREE PHASE/A/B/C kVA MAXIMUM:
The maximum three phase apparent power as well as the maximum
individual phase A/B/C apparent power is displayed in these messages. The time and date at which these
maximum values were measured is also displayed in these messages. This information is stored in non-vola-
tile memory and will be retained during a loss of control power. The phase A/B/C maximum apparent power
messages will be displayed only for a WYE connected system. The setpoint

THREE PHASE/A/B/C PF MAXIMUM:
The maximum three phase lead or lag power factor as well as the max-
imum lead or lag individual phase A/B/C power factor is displayed in these messages. The time and date at
which these maximum values were measured is also displayed in these messages. This information is stored
in non-volatile memory and will be retained during a loss of control power. The phase A/B/C maximum lead or
lag power factor messages will be displayed only for a WYE connected system. The setpoint
