
If the inverter has an 8-pin terminal block connector for Ethernet communication:

Pull the connector out, as shown below:
Screws

Loosen the screws, except for that of pin G. Insert the ends of the wires into the pins according
to the following table:


Tighten the screws of the Ethernet terminal block.

Check that the wires are fully inserted and cannot be pulled out easily.Push the Ethernet
terminal block firmly all the way into the Ethernet connector on the communication board.

If the inverter has an RJ45 connector for Ethernet communication, use a pre-crimped cable to
connect via gland no.1 to the RJ45 plug on the inverter's communication board, or, if using a cable
drum, connect as follows:

Insert the cable through gland no.1.

Remove the cable's external insulation using a crimping tool or cable cutter and expose eight
wires.

Insert the eight wires into an RJ45 connector, as described in Figure 17.

Use a crimping tool to crimp the connector.
