1.2 Overall installation drawing

3.1 Inspect before operation
Before operation, please check carefully and make sure the following items :
The installation position of the AC charging station must convenient for operation and maintenance.
The AC charging station and its accessories must be correctly connected and installed 󽗉rmly.
Reasonable selection of the protection switch for the AC input end.
Don't left external objects or components on the top of the AC charging station.
3.2 Power on the device
a. Make sure that the above inspection items meet the requirements before operation.
b. Switch on the power input end residual current circuit breaker.
c. After the AC charging station is connected to the power supply: there is about 7 seconds
power-on self-test time, and the indicator lights will display red, blue, and green alternately.
d. After the power on self-test is completed, the blue indicator 󽗊ashes at 1Hz.
3.3 Get started
a. Remove the charging gun head cable from the charging pile and correctly insert it into the AC
charging terminal block (cable version) on the vehicle end. Or plug one end of the charging gun
cord into the socket of the charging pile, and plug the other end into the AC charging terminal
block on the vehicle end (socket version).
b. At this time, the AC charging pile will automatically exchange data with the vehicle and
automatically start the charging process. For the status indication status during the operation of
the AC charging pile, please refer to the next 3.4 indicator and working status description.
c. If the AC charging pile fails, please refer to the next 3.4 indicator and working status description
for its failure status.
