OPTIONAL CIRCUIT RATINGS
For the fastest charging in the United States,
using a circuit breaker rated for 100 amps is
recommended. For other regions, use an
appropriate overcurrent protection device as
required by local regulations. In certain home
or office locations, this level of power isn't
readily available. Therefore, you can adjust the
current setting on the Wall Connector from 12
to 80 amp operating current (see page 16).
SELF-MONITORING AND
RECOVERY
The Wall Connector has a ground monitoring
circuit that continuously checks for the
presence of a safe ground connection and
automatically recovers from faults. Manual
testing and resetting is not required.
Temporary problems such as ground faults or
utility power surges are overcome
automatically. If a GFCI fault occurs that
interrupts charging, the Wall Connector
automatically tries to clear the fault and
re-attempt charging.
If the problem is immediately sensed a second
time, the Wall Connector waits 15 minutes
before trying to charge. This process repeats
eight times and if all attempts are
unsuccessful, power is removed and no further
attempts are made. In this case, a red error
light lights up on the front panel (refer to the
troubleshooting table on page 19). It is
recommended that when you see a red error
light, you power off the Wall Connector and
then power it back on again.
4
POWER OUTAGES
If a power outage occurs, the Wall Connector
automatically resumes charging when power is
restored. If the charging cable is plugged into
the vehicle when power is restored, the lights
blink and the unit does not energize the
charging cable for approximately 15 seconds
to 3 minutes. This prevents the utility grid from
experiencing a large surge when power is
restored, allowing vehicles to begin drawing
current at random times, rather than all at
once.
