Have your electrician adjust the Wall Connector’s internal rotary switch to a valid operating current setting. They should first
make sure there is no power to the Wall Connector. The correlation between switch setting and current should be printed on
the inside of the Wall Connector. Your electrician should 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 (circuit breaker sharing) and paired with other Wall Connectors, the rotary
switch of the primary 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 primary unit needs to be set to a current of at least 3 * 6A =
18A or greater.
For more information, see the installation guide for your Wall Connector.

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 charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
1. If the issue persists, turn OFF the circuit breaker servicing the Wall Connector, wait 10 seconds, turn the circuit breaker ON
again, then try reconnecting the Wall Connector to the vehicle.
2.
If the issue persists and other charging equipment is available, plug the vehicle into another Wall Connector or a Mobile
Connector to determine if the vehicle is able to communicate with other charging equipment.
3. If the issue persists, service is required.
For more information, see the installation guide for your Wall Connector.
CC_a030
Unable to charge - Primary / paired unit mismatch
Wall Connector current ratings must match
What this alert means:
Load sharing (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. Have your electrician inspect the type labels on the Wall Connectors and make sure the current capabilities match. It
is further recommended that your electrician only pair Wall Connectors with the same part number, as an easy way to make
sure paired units are compatible.
For more information, see the installation guide for your Wall Connector.
