Connect Powerwall+ to the Backup Gateway

Hardwired communications enter the Backup Gateway via the selected knockout. Run either LFNC or TCER cable using an appropriate ½ inch NPT fitting. Installer preference, Utility, and/or AHJ requirements will dictate whether LFNC or TCER cable should be used.

Run the 4-conductor communication cable through the conduit or cable gland and pull it into the Backup Gateway.

Wire the 4-conductor communication cable to the 4-pin connector plugged into the corresponding connector socket on the Backup Gateway:

Strip the communication wire jacket about 3 inches and strip each conductor 0.4 inches (10 mm).
Cut back the drain wire. The drain wire should be terminated at the Powerwall+ solar assembly ground terminal only.
Insert a cabinet tip or electronics tip slotted screwdriver (up to 3 mm or 3/32 inch) to open each connector lever.
Insert each conductor as far as possible into the terminal and then release the connector lever to close the connector.

Plug the 4-pin connector into the 4-pin socket labeled "Powerwall". Tighten the screws on the connector.

Wire the 4-conductor communication cable to the Powerwall+ solar assembly:

Strip the communication wire jacket about 3 inches and strip each conductor 0.4 inches (10 mm).
Insert a cabinet tip or electronics tip slotted screwdriver (up to 3 mm or 3/32 inch) into each actuation shaft to open the terminal.
Insert each conductor as far as possible into the terminal and remove the screwdriver from the actuation shaft to close the terminal.
