Step 1: Wire Live into port 4 and Neutral into port 3.

Step 4: On the other side of the CAT-5 or CAT-6, use a RJ45 connector and connect solid brown or blue (depending on the cable you use) into pin 4 and brown/white or blue/white (depending on the cable you use) into pin 5.

Please refer to the illustration below, which shows the pin-out configuration for your reference. Please note that this may vary according to the inverter model.

Step 5: Connect the RJ45 into the METER port or RS485 in case your inverter does not have this port.

Step 6: Go to "Advanced Settings" on the inverter screen and enable "External Meter for CT", after that select Eastron-1P on the "Meter Select" field.
