Table 8- 64 Format (145) "Direction of incoming supply"
Byte Value Meaning
0 0 From top to bottom
0 1 From bottom to top
The table below shows the format (146) "Direction of rotation of phase". The normal status of
the direction of rotation of the phase can be set using this.
Table 8- 65 Format (146) "Direction of rotation of phase"
Byte Value Meaning
0 0 Right (e.g. L1 – L2 – L3)
0 1 Left (e.g. L1 – L3 – L2 or similar)
The table below shows the format (162) "Voltage transformer". The setting of the primary
connection also influences the location of the measured voltage variables.
Table 8- 66 Format (162) "Voltage transformer"
Byte Value Meaning
0 0 The voltage transformer is delta-connected on the primary side.
0 1 The voltage transformer is star-connected on the primary side.
