OPTIONAL CIRCUIT RATINGS
For the fastest charging, using a circuit
breaker rated for 100 amps is recommended.
In certain home or office locations, this level of
power isn't readily available. Therefore, you
can adjust the current setting on the High
Power Wall Connector for 40 to 100 amp
breakers (see page 15).
SELF-MONITORING AND
RECOVERY
The High Power 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 High Power Wall
Connector automatically tries to clear the fault
and re-attempt charging.
If the problem is immediately sensed a second
time, the High Power 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 18). It is
recommended that when you see a red error
light, you power off the High Power Wall
Connector and then power it back on again.

POWER OUTAGES
If a power outage occurs, the High Power 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.
