Installing the PLC Box and Data Logger
CAUTION
Disconnect the PV circuit from any grid power before installing the PLC box to
the AC trunk cable or AC junction box.
Step 1:
Connect the Data Logger to the Router.
There are two ways to connect the data logger. One way is a direct Ethernet
connection and the other is through a power bridge connection. If the data logger
can be placed nearby the router, then a direct Ethernet connection will be setup.
If the data logger cannot be placed near the router, then a power bridge
connection will be setup.
Note: To mount the data logger, use the included wall-mount frame.
Option 1:
Direct Ethernet Connection
Connect the data logger to the router with the Ethernet cable. If the
Ethernet cable does not reach the router, either a longer Ethernet
cable is needed or setup a power bridge connection.
Option 2: Power Bridge Connection
A Power Bridge connection is suggested to be used with the data
logger cannot be place near the router. The Power Bridge comes in
a set of two. Plug in one to the Power Bridges to a nearby AC outlet
and connect it to the data logger. Plug in the other Power Bridge to
an AC outlet near the router and connect it to the router.
Step 2:
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
