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 20: RS485 chain of meters

Connecting Two Meters

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

2. Connect the meters to the inverter or Commercial Gateway

RS485 connector as illustrated below.
