Branch current shock protection alarm threshold. The value range is 150%-500%, and
the default value is 300%. When the ratio of the branch current to the rated branch
current exceeds the value of Br. cur. shock protect (%), an alarm will be generated.
X harmonics, Y harmonics, and Z harmonics
The number of three categories of harmonics is displayed. The value range is 2-63. The
default values of X harmonics, Y harmonics, and Z harmonics are 5, 7, and 11,
respectively. The system displays the harmonics settings in Cabinet Input.
