Troubleshooting Tip
Why is my EV charger not charging
my EV?
Check to see if the EV charger is powered and the LCD screen is showing the home
screen. If not, check if the EV charger is wired properly and the circuit breaker is closed. If
the problem persists, contact and certified electrician.
If the EV charger continues to show ‘Plug in your vehicle’ screen, then make sure the
J1772 connector is properly plugged into the EV.
If the EV charger is displaying an authentication screen (Scan QR or Swipe Card to Start),
then it is networked charger managed by a CPO. You will need the CPO subscription and
authorization credentials to use this charger.
I see a blinking BLUE LED but my
EV charger and my EV is not charging.
Blinking BLUE LED indicates that EV charger is plugged into an EV but either the EV
charger or the EV are not ready to start the charging. Refer to the ‘Routine Operation’
section of the Instruction Leaflet for more details.
If the EV is not ready, check if its battery is fully charged or if there is a fault on the EV
that is preventing it from initiating a charge.
Why do I see the ‘authorization failed’ message on
the EV charger?
If an RFID is used for authentication, please make sure that RFID card used is issued by
the authorized CPO. Swipe the card over the RFID module properly and make sure that
you hear a beep from the charger.
Note that the authentication screen is timed. If authentication process does not start
within the stipulated time, the EV charger will timeout and ‘authentication failed’
message is displayed.
Contact a certified electrician to make sure the RFID module is not disconnected from the
main EV charger electronics
Why is the LCD screen on my
EV charger blank?
Check if the EV charger is wired properly and the circuit breaker is closed. Restore the EV
connector back to the charger and try to reset the circuit breaker powering the charger. If
the problem still persists, contact and certified electrician.
I see a blinking RED LED on my EV charger.
What does this mean and how can I resume
normal operation?
RED LED on the EV Charger blinks for various fault conditions.
Some of those conditions include:
1. EV charger fault (Over/Under voltage, Ground Fault): 1 second blink
2. EV Fault: 0.5 second blink
3. Control Pilot signal fault: Steady on
LCD also displays a fault code for each of these errors. To resolve these conditions,
contact a certified electrician to check Voltage levels feeding the charger. Check for any
obvious grounding issues in wiring. Also check if L1, L2 and GND wires are connected
per guidelines.
I unplugged EV connector in the middle
of a charge and now the EV charger
is not charging.
If you were using a networked charger that is controlled by a CPO, then removing the EV
connector in the middle of a charge session will end that session. A new session needs
to be initiated. For a non-networked charger, a new charging session will automatically
start once the EV connector is plugged back into the EV.
Have trouble connecting the EV charger
to the CPO
Refer to the EV charger product page for instructions on commissioning the EV charger
using Wi-Fi, Ethernet, or cellular and connecting to a CPO provider.
My EV does not have a J1772 port.
Does this charger work with my EV?
Certain manufacturers like Tesla utilize a proprietary connector on their vehicles. In
this scenario, the cars will ship with an adapter that will allow you to use SAE J1772
connector like the one on Eaton EV charger. Please check instructions that came with
your car on where to find this adapter or contact your manufacturer. SAE J1772 is a
universal charging connector widely adopted by most EV vehicle manufacturers.
