I would plan for the unpowered IN-EVSE to have open relays to both Power lines, both control lines (no Control Pilot and no Proximity), and even the Ground.
Gary, if you open the relays at the same time as you de-assert proximity, your relays are going to likely have a short life. Also, does the Open EVSE have relay contact welding detection? Most EVSE's do.garygid said:I would plan for the unpowered IN-EVSE to have open relays to both Power lines, both control lines (no Control Pilot and no Proximity), and even the Ground.
