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