1. Strip the communication wire 20mm, and arrange the wire according to the color as shown in the
above diagram
2. After inserting the terminal head, you need to push the wire to the top with force. After crimping the
terminal, you need to check if the top is in good contact. If the meter still can't communicate after
connecting, you need to recheck if the crimping is correct.
DRM port
DRM communication port is used to connect the DRM controlling device.
When using DRM port, the PIN7 and PIN8 of inverter’s RJ45 plug cannot connect wires. The PIN7
and PIN8 of external DRM adapter’s RJ45 plug must be short connected together.
Meter port
Meter communication port is used to communicate with smart meter to achieve zero-export. The
connection between smart meter and inverter and grid is as shown in Figure3-50, Figure3-51,
Figure3-52, Figure3-53.
