Unable to charge - Incorrect switch setting
Wall Connector rotary switch must be adjusted
What this alert means:
Incorrect rotary switch setting.
What to do:
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.
