DEM1A001

Note: 23:SO1 is SO output for kWh or Active/reactive forward kWh optional

24:SO2 is SO output for kvarh or Active/reactive reverse kWh optional

25:G is for GND

For Neutral wire, you can connect one N port and connect both.

DEM1A002/102

Note: 23.24.25 is for A+, G, B-.

If the RS485 communication converter doesn’t have G port, no need to connect.
