Solution:
Correct the connection, execute the “Automatic initialisation (AI)” or add 180° to resp. subtract
180° from the set phase correction angle (SETUP/206) (new angle < 360°).
Please observe the separate notes at the end of the chapter for the setting of the phase
correction angle.

incorrect connection
Incorrect phase between measuring voltage and current. Please check the connection of measuring
voltage and current (phase, polarity).
Possible causes:
The set phase correction angle does not correspond to the connection of measuring voltage and
current.
Solution:
Correct the connection, execute the “Automatic initialisation (AI)” or manually set the phase
correction angle correctly.
Measuring voltage or current has been connected at a twisted angle of 180° from the direction of
connection (U2 / U1 instead of U1 / U2 resp. S2 / S1 instead of S1 / S2).
Solution:
Correct the connection, execute the
“Automatic initialisation (AI)” or add 180° to resp. subtract
180° from the set phase correction angle (SETUP/206) (new angle < 360°).
Please observe the separate notes at the end of the chapter for the setting of the phase
correction angle.

The “Automatic initialisation” (AI) was cancelled with error.
Possible causes:
Heavy load fluctuations during the “Automatic initialisation (AI)”
Solution:
Restart the “Automatic initialisation (AI)”, when the mains is steadier. The measuring current
was too small.
The current transformer ratio may be too large.
Solution:
Check if the selected current transformer corresponds to the system and change it, if
necessary. Restart the “Automatic initialisation (AI)”.
