7. You can optionally draw the current measurement and the amount of phases in your online diagram (refer to
Figure 3-45).
Please consider following rules (for a better overview and understanding):
• The current measurement is always on system A. So the locations for the CT are fixed for DSLC-2 and
MSLC-2 (only located at the utility).
• MSLC-2 located at tie-breaker: When the CT at the tie-breaker is located on the right side it is allowed
to turn system A and system B measurement at the tie-MSLC-2. But please draw this clear in your on-
line diagram.
• The positive power flow for MSLC-2 power measurement is defined from A to B.
• The busbar measurement can be 1-phase or 3-phase. Please remark this with lines over the busbar / sys-
tem B measurement.

1. Menu 5 Device number (parameter 1702): Enter the according device number in the particular units
2. Menu 5 Basic segment number (parameter 4544):
• DSLC-2: Enter the according segment number of the particular unit.
• MSLC-2 at the utility breaker: Enter the according segment number of the particular
unit.
• MSLC-2 at the tie-breaker: Enter the according segment number which is resided on
