Troubleshooting Alerts
Make sure there is no power to the Wall Connector.
Remove the face plate and adjust the rotary switch to a
valid operating current setting. The correlation between
switch setting and current is printed on the inside of the
Wall Connector. You can also refer to the Set the
Operating Current section in the Wall Connector
Installation Manual. If the Wall Connector is set up for
load sharing (paired with other Wall Connectors), the
rotary switch of the master unit must be set to an
operating current setting that allows each paired Wall
Connector to receive at least 6A of charge current.
Example: Three Wall Connectors are paired for load
sharing. The master unit needs to be set to a current of
at least 3 * 6A = 18A or greater.

Unable to charge - Vehicle
connection issue
Insert charge handle fully into
charge port
What this alert means:
A communication error occurred between the Wall
Connector and the vehicle.
What to do:
Try again by disconnecting the Wall Connector from the
vehicle and reconnecting. If possible, plug the vehicle
into another Wall Connector or a Mobile Connector to
determine if the vehicle is able to communicate with
other charging equipment. If the problem persists,
contact Tesla.
(CC_f030)
Unable to charge - Primary / paired
unit mismatch
Wall Connector current ratings
must match
What this alert means:
Circuit Breaker Sharing Network: The paired Wall
Connectors have different maximum current capabilities.
What to do:
Only Wall Connectors with the same maximum current
capabilities can be paired in a load-sharing (circuit
breaker sharing) network. Inspect the type labels on the
Wall Connectors to make sure the current capabilities
match. It is further recommended to only pair Wall
Connectors with the same part number, as an easy way
to make sure paired units are compatible.
