Wire Communications from Powershare Gateway to Backup Switch

Informational PurposesAn informational icon, calling your attention
Note
Refer to Appendix A: Wiring Reference for all wiring specifications.

Depending on local requirements, communication wiring can be installed through conduit or through a cable gland. Refer to local codes to determine wiring requirements.

  1. Hardwired communications enter the Backup Switch via the conduit hub. 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.
  2. Run the 4-conductor communication cable through the conduit or cable gland and pull it through the Backup Switch conduit hub.
  3. Wire the 4-conductor communication cable to the Backup Switch connector:

    CAUTION
    Always wire the Backup Switch connector before plugging it in to the Backup Switch. The force exerted to lock each terminal can potentially damage the Backup Switch, so wires must be placed and terminals locked before plugging the connector into the Backup Switch.
    1. Strip the communication wire jacket about 3 inches. Do not strip the individual communication wires.
      Informational PurposesAn informational icon, calling your attention
      Note
      The communication connector is insulation displacing, meaning it pierces the insulation of the unstripped wires to make strong electrical contact. Stripping the individual wires may result in wires jamming the connector.
    2. Cut back the drain wire.
    3. Insert a cabinet tip or electronics tip slotted screwdriver (up to 3/32-inch or 3 mm) to open each connector lever.
    4. Insert each conductor as far as possible into the terminal and then use the screwdriver to close the connector lever.

    Note
    Reference Backup Switch Wiring for the correct wire order in the Backup Switch connector.
  4. Plug the connector into the corresponding connector socket on the bottom of the Backup Switch.
  5. Adjust wire slack, or coil the wires as necessary.

    Note
    Leave approximately 5 inches of slack in the wiring.
  6. Secure the conduit hub:
    1. Mount the conduit hub over the communication cable connector.
    2. Using a Phillips PH2 screwdriver, tighten the (3X) captive fasteners to 1.5 Nm (hand-tight) to hold the hub in place.
    3. Route the 4-conductor communication cable from the Backup Switch to Powershare Gateway.

      Note
      Provide attachment points to secure cable/LFNC to wall as defined by NEC.
  7. On the Powershare Gateway Tesla Asset Controller, remove the CAN TERM jumper, then reinstall it so that it is in the OFF position.

  8. Disconnect the factory wiring harness from the Powershare Gateway communication connector.
  9. Pull the Backup Switch communication wiring through one of the Powershare Gateway knockouts.
  10. Using 3-port WAGO connectors, connect the Backup Switch communication wiring with the factory wiring harness.
  11. Connect communication wiring from the third port of each WAGO connector to the Powershare Gateway communication connector:

    3. Insert each conductor as far as possible into the terminal and then use the screwdriver to close the connector lever.
    4. Plug the communication connector into the corresponding connector socket in Powershare Gateway.
    5. If the communication wiring has a metal shield or drain wire, cut the excess shield and/or drain and insulate it with electrical tape.

      CAUTION
      If the optional metal shield / drain is not properly insulated, it could contact the live electrical components in the Powershare Gateway, resulting in equipment damage.
  12. After all connections have been made, route the communication cable up and around the internal panelboard.
