Unable to charge – Incorrect switch
setting
Adjust rotary switch setting in Wall
Connector
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.
