Throughout this document, the phase-to-neutral notations of A/B/C and L1/L2/L3 as well as the phase-
to-phase notations of AB/BC/CA and L12/L23/L31 may be used interchangeably for specifying a certain
parameter to be a phase-to-neutral or phase-to-phase value, respectively.
The following sections illustrate the available measurements for each display option. Depending on the
Wiring Mode selected, certain measurements may not be available. For example, the per-phase Uln,
Uln Average, per-phase kW, kvar, kVA and PF measurements are not available when the Wiring Mode
is set to 3P3W or 1P2W L-L.
