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.
