Appendix B: Installing Two  Meters

You can connect up to two meters on the same bus. 

To connect two meters, install two wires into each screw 

terminal by twisting the wires together, inserting them into 

terminal, and securely tightening. RS485 wiring is daisy-

chained between meters, as described in the following figure:

Figure 16: RS485 chain of meters

Connecting Two Meters

 1.  Connect the twisted pair wiring to the meters as shown in 

Appendix B.

 2.  Wire the RS485 connections between the meters and the 

inverter or Commercial Gateway.

 3.  Set the meters' 120 ohm termination DIP switches as
