Ensure no more than 3 units paired with primary
What this alert means:
Load sharing (circuit breaker sharing) network: More than three Wall Connectors are paired with the same primary
unit.

Unable to charge - Low Wall Connector current
Primary unit current setting must be increased
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.
