Phase-Phase Voltage Measuring
It is also possible to perform a phase-phase voltage measuring. The units is intended for a phase-neutral measur-
ing as described above, but may also be used for phase-phase voltage measuring. In this case, phase L2 must be
connected to the N terminal of the DTSC-50 and the Generator rated voltage (Parameter 11) must be configured
to the phase-phase voltage.

NOTE
If you select to perform a phase-phase voltage measuring, the display is still indicating a phase-neutral
voltage since the voltage is measured between terminal 33 (L1) and 35 (N).
However, if the Generator rated voltage (Parameter 11) is configured correctly, the displayed value is
the correct phase-phase voltage value.
