Installing the PLC Box and Data Logger
Step 1:
Install the PLC Box.
Connect DC power to the PLC Box through 12V/1A AC adaptor. Connect the AC wiring (PLC
Signal) from the PLC Box to the AC Trunk Cable or the AC Junction Box. The PLC Box will
need to be placed in and secured to the AC Junction Box. The wires in the AC trunk cable
are identified by color.
CAUTION
Disconnect the PV circuit from any grid power before installing
the PLC box to the AC trunk cable or AC junction box.
Step 2:
Connect the Data Logger to the Router
Place the data logger near the router, then make a direct Ethernet connection. If the data
logger cannot be placed near the router, then the installer can add either a wireless access
port or a power line communication port (not supplied with the micro inverter).
Note: To mount the data logger, use the included wall-mount frame.
Step 3:
Connect the Data Logger to the PLC Box
Insert the red/black wiring into the RS485 connectors, and then insert the connectors into
the Data Logger and PLC Box. (Ensure there is length of the red/black wiring is sufficient for
installation)
Note: Ensure the RS485 connectors are wired properly.

Note: If installing more than one PLC Box in the system, daisy-chain the PLC
Boxes together using RS485 cables. Then connect the last PLC Box in
the series to the Data Logger using the RS485 cable.
