3-Phase 4-Line 2PT mode (2LN)
In some 3-Phase 4-Line Wye systems, 2PT Wye mode is often used as in
g 2.12. It is supposed that the 3 phases of the power system are balanced. The
voltage of V2 is calculated according to V1 and V3. The voltage input mode of
the DPMS XPQ should be set to 2LN for 2PT voltage input wiring mode.

3-Phase 3-Line open Delta Mode (2LL)
Open delta wiring mode is often used in high voltage systems. V2 and
Vn connect together in this mode. The voltage input mode of the DPMS XPQ
should be set to 2LL for voltage input wiring mode.
