2Charging Operation
2.1 Plug-and-Charge Mode (Default )
When the charging station is on standby, plug in the connector to your EV, and
the LED will turn blue from purple.
The LED will be flashing green while charging.
When your EV is fully charged, the LED will be solid green, unplug the connector
and place it back into the holster.
If you need an emergency stop while charging, please press the RESET
BUTTON then unplug the connector.
1. without any operation.
2. Once you enable the RFID mode, the plug-and-charge mode will be
disabled, if you want to use the plug-and-charge mode, please contact us

Problems
Solutions
The red light flashes slowly once
and quickly once, alternately
cycle.
Grounding Fault
1. Immediately turn off the
leakage/overcurrent protection switches in
the power distribution box.
2. Check whether the input cables
are grounded correctly.
3. After the fault is rectified, power
on the device again. If the fault persists,
contact us.
The red light flashes slowly twice
and quickly twice, alternately
cycle.
Output Overcurrent
1. Immediately turn off the
leakage/overcurrent protection switches in
the power distribution box.
2. Check whether there is low
impedance or short circuit between the
charger output line.
3. Ensure the charging current to
less than 35A.
4. After the fault is rectified, power
on the device again. If the fault persists,
contact us.

The red light flashes slowly twice
and quickly for 4 times,
alternately cycle.
Over-heating
1. Check the charger installation
environment.
2. Check whether there are other
heating devices nearby.
3. Ensure that the ambient
temperature is below 50℃.
The red light flashes slowly for 3
times and quickly for 2 times,
alternately cycle.
Input Overvoltage
If the voltage exceeds 265Vac for a short
time,wait for the power gird to restore itself
to the normal voltage range. Contact local
power grid company if the voltage fault
persists.
The red light flashes slowly for 3
times and quickly for 3 times,
alternately cycle.
Input Undervoltage
If the voltage under 90Vac for a short
time,wait for the power gird to restore itself
to the normal voltage range. Contact local
power grid company if the voltage fault
persists.
The red light flashes slowly
twice and quickly once,
alternately cycle.
Relay Adhesion
Please contact us if the fault persists.
The red light flashes slowly for 2
times and quickly for 3 times,
alternately cycle.
Residual Current
Detected
1. Immediately turn off the
leakage/overcurrent protection switches in
the power distribution box.
2. Check whether the charger output
line is damaged or has low impedance to the
ground or short circuit.
3. After the fault is rectified, power
on the device again. If the fault persists,
contact us.
The red light flashes slowly for 3
times and quickly once,
alternately cycle.
L/N Connected
Reversely
1. Immediately turn off the
leakage/overcurrent protection switches in
the power distribution box.
2. Check whether the input L/N
cables are connected in correct sequence.
3. After the fault is rectified, power
on the device again. If the fault persists,
contact us.
