3.4 Technical Information

**WattStation determines the maximum power consumption. EV determines the actual power
consumption.

3.5 Fault Indication

When the fault indicator illuminates red, WattStation is indicating a fault.
Ground Fault: WattStation can detect the presence of ground faults with a threshold of 15–20 mA during
the charging cycle. Once a ground fault is detected, WattStation will stop charging the vehicle and the
fault status indicator will turn red. The WattStation will automatically reset after 15 minutes or if the EV
connector is disconnected from the vehicle.
If four (4) such attempts to restart charging have occurred, WattStation will lockout the station. The
lockout will prevent any vehicle from being charged until the EV connector has been disconnected from
the vehicle. The fault indicator will illuminate as solid red. It is highly recommended that service
personnel examine the EV (electric vehicle) and/or the charging cable to determine the cause of the
multiple faults before re-energizing.
If a ground fault is present immediately after WattStation begins charging, the unit will stop charging and
immediately lockout the station. The lockout will prevent any vehicle from being charged until the EV
connector has been disconnected from the vehicle. The fault indicator will illuminate as solid red.
Fan Fault: WattStation is not suitable for vehicles that require ventilation. It will provide fault indication if a
vehicle requests fan ventilation, as per SAE J1772. The fault indicator will illuminate and turn solid red. The
fault will reset if the user removes the WattStation connector from the vehicle.
Overvoltage/Undervoltage Faults: WattStation monitors line voltage and cuts power to the EV if the
voltage goes out of range. After one (1) minute, it rechecks the voltage and will automatically re-enable
charging if the voltage returns to an acceptable range. The fault indicator will illuminate as blinking red.

3.6 Fuse Replacement

In the event that a fuse needs to be replaced, de-energize the upstream breaker feeding this equipment
before opening the cover. Remove the front cover as described in Step 4 of Section 2.32. The fuses will
then be accessible through the dead front shield. Remove old fuses by using a fuse puller tool.
Replacement fuses should be Cooper-Bussmann NON-40, Class K5.
