Setting [APPL-Ves2] = Off
If no voltage is applied at the Vs2/Ve terminal, the user can set
Off
for the setting [

Settings CT polarity setting in 1CB or 1.5CB
The user can reverse the CT polarity using settings. For example in 1CB arrangement, when
the user wishes to change the polarity to negative in the first currents group (that is, Ia, Ib,
and Ic on the VCT; we term them ‘1CT’), set
Negative
for the setting [
Pol-1CT
].
