RS485 Connection

Recommend that RS485 can be connected by terminal blocks. Please note SG15/20KTL-MT inverters connection is different as SG30/50/110CX inverters.

Diagrams show RS485 terminal block connections for inverters, with A1, B1, and PE terminals labeled.

Optional: Ensure the termination resistors (120 Ohm) are enabled ON (SW1) at each end of the RS485 in the inverter line when more than 15 inverters are connected.

A diagram illustrates the optional termination resistor setup (SW1) on the inverters, showing 'OFF' and 'ON' positions for the 120 Ohm resistor.

Energy Meter Connection

The site electrician will need to calculate the CT ratio required as per the installation. The CT ratios can be set by accessing the DTSD1352 energy meter. Please refer to the Meter Selection Guide for reference. Default Modbus address is 1 and the secondary current of CT should be 5A.

The corresponding pinouts to RJ45 are Pin 3 (White-green) to RS485- B and Pin 6 (Green) to RS485+ A.

If the communication cable is Shielded Ethernet cable, white-green cable 3 is defined as RS485- B cable and the green cable 6 as RS485+ A cable.

Terminal 21 to Green cable (RS485+ A) and terminal 22 to White-green cable (RS485- B) on the DTSD1352 energy meter side. A diagram shows the DTSD1352 energy meter with terminals 21 and 22 labeled for RS485+A (Green cable) and RS485-B (White-green cable) respectively. It also shows other terminals like L1, L2, L3, N.
