  1. Connect the CAT6 or higher communication cable that came with the HELIOS ESS battery to the inverter’s CAN port, and pass the other end of the cable through the conduit box to connect to the battery’s COM2 port (CAN port).

  2. If setting up closed-loop communication without the LYNK II Communication Gateway (950-0025), and the HELIOS ESS battery is supplied with a termination resistor, insert the resistor into either the COM3 or COM4 port.

  3. Re-attach the battery terminal cover plates.

NOTE

For shipping purposes, the cover plate is attached inside-out. Please attach the cover plate so that it juts out and provides room for the battery and communication cables.
