(Optional) Installing the Signal Cable
•
Not all inverter models are delivered with the signal cable connector.
•
When laying out the signal cable, separate it from the power cable and keep it away from
strong interference sources to avoid strong communication interference.
•
Ensure that the protection layer of the cable is inside the connector, surplus core wires are cut
off from the protection layer, the exposed core wire is totally inserted into the cable hole, and
that the cable is connected securely.
•
If the Smart Dongle is configured, you are advised to install the Smart Dongle before
connecting the signal cable.
