HIGH POWER WALL CONNECTOR
3
FEATURES
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 12).
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, you’ll see a red error light
on the front panel (refer to the troubleshooting table on page 14). 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 the vehicle to begin drawing current at random times,
rather than all at once.
