Warning Assembly of a Electric Vehicle charging station requires wiring Alternating Current (AC) components that will be exposed to voltages from 100 to 250v. If you do not have the experience and knowledge required to safely work with AC voltages please consult with an experienced electrician for assistance and inspection of your work.

Note Regularly inspect your charging station (OpenEVSE or Commercial). Pay special attention to excess heat, components, handles, and wiring will be warm but they should not be HOT...

Important Always Disconnect your charging station from power before performing an inspection and/or maintenance.

Warning Do not install OpenEVSE near flammable, explosive, or combustible materials. Do not locate or store flammable, explosive, or combustible materials near the charging station.

Warning Do not operate the EVSE with a visibly damaged cable or if the enclosure or connector is broken, open, cracked, or shows any other signs of damage.

Warning Adult supervision is required when building, operating, servicing or inspecting.

OpenEVSE can be powered by a single phase in the following configurations:

• 240VAC single-phase: L1, L2, and safety ground

• 240VAC split-phase: The two phases must both measure 120V AC to ground.

• 208VAC 3-phase, wye-connected: Any 2 phases and safety ground

• 230V AC single-phase Line, Neutral, and EARTH

• 50 or 60Hz

Note - OpenEVSE supports 3 phase charging stations, the controller is powered by a single phase and 3 phases are provided to the Electric Vehicle.

OpenEVSE will display various colors based on state if equipped with a Red - Green - Blue (RGB) Liquid Crystal Display (LCD) or a RGB Light Emitting Diode (LED).

The colors are:

Color	OpenEVSE State	EV State	J1772 State
White	Booting	N/A	N/A
Green	Ready	Not Connected	State A
Yellow	Ready	Connected	State B
Blue	Charging	Charging	State C
Red	Error	N/A	Error

The Standard LCD used on OpenEVSE projects has 2 lines and 16 Characters per line.

Top Line Left Side

Ready	OpenEVSE is ready
Charging	OpenEVSE is ready to Charge
Error	OpenEVSE has detected an Error
Stopped	OpenEVSE has been stopped
Waiting	OpenEVSE is waiting for a timer
Sleeping	OpenEVSE is sleeping

Top Line Right Side The Right side displays information about the Service level and Current setting of the Pilot. In the "Ready" States the LCD displays the Service Level L1 - 120V or L2 - 240V and the Maximum current allowed by the Charging Station.

Bottom Line The Bottom line displays information about the state of the Electric Vehicle and the current charging session.

EV Not Connected	OpenEVSE does not detect an EV
EV Connected	OpenEVSE detected an EV

In the Charging state the LCD will display Elapsed time since the Charge session started and the current time reported by the real time clock.

Errors Power on Self Test

GFCI Self Test Failed	OpenEVSE did not detect a GFCI Fault during test	Check GFCI CT and Self test coil
Earth Ground Test Failed	OpenEVSE could not detect a Ground	Check Ground Connections and AC_Test lines
Stuck Relay Test Failed	OpenEVSE read AC voltage before Relays were closed	Check Relay and AC_Test Lines

Errors

GFCI Fault	OpenEVSE detected a ground leakage of > 20ma	OpenEVSE will retry charging after 15 minutes up to 4 times
No Ground	OpenEVSE lost connection to ground	Check Grounds and AC_Test lines
Vent Required	OpenEVSE read a pilot signal at 3V	Ventilation required State
No Diode	OpenEVSE did not detect the J1772 Vehicle diode

Real Time Clock allows you to set the current time and set up Start and Stop times. These timers are independent to to timers on the vehicle.

Optional Battery - Insert a CR1216 or CR1220 coin cell battery if you wish to keep current time after power failure with the Real Time Clock option.

OpenEVSE was designed to comply with safety features required by standards documents for Electric Vehicle Charging from SAE J1772, NEC and UL.

•UL2251 Standard for Plugs, Receptacles and Couplers for Electric Vehicles

•UL2231 Standard for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits

•SAE J1772™ Electric Vehicle Conductive Charge Coupler Standard

•NEC Article 625 Electric Vehicle Charging System Equipment

Note - OpenEVSE has not been tested or certified by a Nationally Recognized Testing Laboratory.

OpenEVSE includes an interlock that de-energizes the electric vehicle connector and cable whenever the electrical connector is uncoupled from the electric vehicle (NEC 625.18)

OpenEVSE supports the SAE J1772 pilot signal which provides an automatic means to de-energize the cable conductors and electric vehicle connector upon exposure to strain that could result in either cable rupture or separation of the cable from the electric connector and exposure of live parts (NEC 625.19) (SAE J1772)

OpenEVSE performs a Self-Testing sequence during start up to ensures unit is working properly and safely upon power-up OpenEVSE checks for:

• GFCI--Ability to respond to a 20mA ground fault

• Missing Ground

• Welded Relay Contact Monitor

OpenEVSE checks ground an power-up and constantly monitors for presence of proper safety ground. (SAE J1772)

OpenEVSE includes mandatory Ground Fault Interruption with a 20ma trip in all models available for protection against electric shock of personnel. (NEC 625.22) (SAE J1772) (UL 2231)

After each GFCI event OpenEVSE will retry charging up to 4 times after a 15 minute delay per event. (UL 2231)

OpenEVSE checks relay contacts on Power up to ensure relays are functioning properly and providing proper Power interlock.

OpenEVSE verify the pilot signal integrity by checking the Electric Vehicle Diode. The pilot signal must BOTH be at the correct resistance AND pass the "diode check" to activate the circuit. (SAE J1772)

Note - This safety feature is commonly left out of commercial charging stations

OpenEVSE checks for the Ventilation required request from Electric Vehicles. OpenEVSE will deny charging if ventilation is not available or allow if charging station is equipped to activate ventilation. (SAE J1772)

Note - This safety feature is commonly left out of commercial charging stations or implemented with a warning label only
