Wire Communications from Powershare Gateway to Backup Switch
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.
- 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.
- Run the 4-conductor communication cable through the conduit or cable gland and pull it through the Backup Switch conduit hub.
-
Wire the 4-conductor
communication cable to the Backup Switch connector:
CAUTIONAlways 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.NoteReference Backup Switch Wiring for the correct wire order in the Backup Switch connector.
- Plug the connector into the corresponding connector socket on the bottom of the Backup Switch.
-
Adjust wire slack, or coil the
wires as necessary.
NoteLeave approximately 5 inches of slack in the wiring.
-
Secure the conduit hub:
- On the Powershare Gateway Tesla Asset Controller, remove the CAN TERM jumper, then reinstall it so that it is in the OFF position.
- Disconnect the factory wiring harness from the Powershare Gateway communication connector.
- Pull the Backup Switch communication wiring through one of the Powershare Gateway knockouts.
- Using 3-port WAGO connectors, connect the Backup Switch communication wiring with the factory wiring harness.
-
Connect communication wiring
from the third port of each WAGO connector to the Powershare Gateway communication
connector:
CAUTIONAlways wire the Powershare Gateway connector before plugging it in to Powershare Gateway. The force exerted to lock each terminal can potentially damage Powershare Gateway, so wires must be placed and terminals locked before plugging the connector into Powershare Gateway.
- After all connections have been made, route the communication cable up and around the internal panelboard.
