Ge Wattstation Connect - GE WattStation Installation And User Manual

3.5.2 Ground Fault protection
Networked Wallmount WattStation includes 15 - 20 mA GF protection per UL 2231.
provides fault indication if a ground fault has occurred. The fault will automatically reset per UL
2231 if the fault has occurred after charging has begun. This reset will occur after 15 minutes.
Only 4 automatic retries can occur in a charging session. Unplugging the EVSE connector from the
vehicle will close out a charging session and reset the number of automatic retries. If the ground
fault is detected immediately after charging, the EVSE will stop charging and indicate a fault.
3.5.3 Ground Monitor Interrupter
The EVSE will perform ground monitoring on the line and load side per UL 2231. Ground
monitoring on the load side requires the EVSE to stop or not initiate charging if earth ground is
broken between vehicle and EVSE. Ground monitoring on the line side requires the EVSE to stop
initiate charging if earth ground is not present on the incoming power side of the EVSE. If the
ground monitor detects the loss of ground on the vehicle side of the EVSE, the EVSE will disconnect
the contactor if charging or prevent charging if the vehicle is requesting charge. If the ground
monitor detects the loss of ground on the line side of the EVSE, the fault icon will indicate fault and
prevent the EVSE from charging a vehicle.
3.5.4 Ventilation Fault
If a vehicle requests facility ventilation, the Networked Wallmount WattStation will not charge the
vehicle and issue a fault indication on the fault icon. The fault will be cleared once the EVSE
connector is removed from the vehicle.
3.5.5 Metering
The Networked Wallmount WattStation measures the voltage, current, power and Energy
consumed by the EV during a charge and the measured data is available through Modbus or
WattStation Connect.

3.6 GE WattStation Connect

GE WattStation Connect is a server application that allows owners to configure and monitor their
EVSEs remotely. GE WattStation Connect also handles RFID authentication and setup. The
customer will access GE WattStation Connect through their web browser on their PC
