(Optional) Installing the Signal Cable
•
Not all SUN2000 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.
