There are three selections that must be verified on this screen:
1. Redefine the demand window, between 1 and 60 minutes by entering the desired
number of minutes into the Demand Window box at the top of the screen.
2. Change the frequency from 60 Hz to 50 Hz in the Line Frequency menu box at the
top of the screen.
3. Redefine a WYE or DELTA wiring configuration for the meter by clicking the
correct button at the top of the screen.
NOTE: For single-phase configuration, select WYE (see MD-P1 and MD-
P1D Power Meters Wiring Diagrams for sample single-phase wiring
configurations).
• Siemens Industry, Inc. recommends using three CTs in a WYE connection for Delta
loads.
•A WYE connection automatically displays all three CTs. Any changes made to CT1
also apply to CT2 and CT3.
•A Delta connection displays only the two available CTs. Any changes made to CT1
also apply to CT3.
• There are no other valid commands to be used here--just data display for
verification.
