FWIW, I inadvertently created a charger fault on my Siemens VersiCharge when we returned from a vacation a few days ago. The car was fully charged, and I then enabled the nightly charge schedule via HondaLink. That was successful, but I forgot that the charger cable was still connected to the car, and the fault resulted. I removed the cable and reset the charger, and there haven't been any problems since, and hopefully no damage was done, but it was troubling. In the future, I will be sure that it is disconnected if I expect to change the schedule.
