Mounting

The EM2GO EV chargers provide a user-friendly operator interface with the appropriate communication interfaces.

Warning: A damaged EV charger must not be installed under any circumstances. In case of damage, please inform your dealer immediately. The installation and wiring must be carried out by a specialist company. EM2GO EV chargers are equipped with a three-phase CEE plug and can be plugged into a suitably installed and secured CEE socket.

The danger of electric shock

Make sure that the plug of the CEE cable is not connected to the mains when connecting to the charging station!

Mounting the supply cables:
First, mount the wall bracket using the mounting accessories included in the scope of delivery.

1. Remove the cover
2. Feed the input cable through the interface
3. Connect the cable plugs to the screw terminal of the charging station as follows and screw this tight (approx. 4Nm): L1 Brown | L2 Black | L3 Gray | N Blue | PE Green-yellow
4. Close the cover (1) again.

Wall mounting

NOTE: Please take into account that the length of the connection cable of the charging unit is 150 cm (±5%), the three-phase junction box should be located in this area. The charging unit is equipped with a residual current device (RCD Typ B). Please ensure that your three-phase socket is equipped with the appropriate fuse switch.

Mounting accessories:

• Wall mount
• Screws for the holder
• Dowels

1. Place the wall bracket where you want to place the charging station. Make sure that the CEE power connection is within a radius of 1.5 meters. Drill 4 mounting holes with a diameter of 10 mm and a depth of 50 mm at the appropriate height
2. Insert and countersink the dowels into the drilled holes.
3. Screw the wall mount to the wall with the screws.
4. Place the charging station on the wall bracket with the rear side facing upwards
5. Fasten the left and right screws to secure the wall box to the wall bracket

Charge the vehicle

Note: The vehicle to be charged must be parked, switched off and the parking brake engaged.

Switch on: After installing and checking the charging station, press the toggle lever of the circuit breaker
in the input terminal box of the charging station upwards to establish the power supply. The power LED lights up and the charging station switches to standby mode.

1. Remove the type 2 plug from the charging plug holder (CT) and connect it to the vehicle‘s charging port. Please ensure that the vehicle is prepared and set for charging. If you have purchased the charging station as a socket variant (ST), first connect your Type 2 charging cable to the Type 2 socket of the charging station, and then to the charging port of your electric vehicle.
2. The charging process starts when a pre-configured RFID card touches the designated area for RFID application. Also, the charging process can be stopped by touching the area with the RFID card. 3.
3. After charging is complete, remove the Type 2 plug from the vehicle‘s charging port. Insert the type 2 plug into the charging plug holder (CT). If you have purchased the charging station as a socket variant (ST), put the protective cap back on type 2 charging plug. If you cannot pull out the plug, press the unlock button of the vehicle or key.
4. Emergency stop button Press this button to stop the charging process immediately.

Communication

The charging station has the following interfaces for communication: Wi-Fi, Ethernet, RS-485.
If the charging station is connected to an Internet connection via the Wi-Fi or Ethernet interface, the charging station can be connected to a backend for the management of charging
stations via OCPP (Open Charge Point Protocol). The charging station can be programmed, controlled, and monitored via RS-485.

WiFi

Attention: An app for operation is not available.

1. Prepare a 2.4 GHz WiFi router and an Android or iPhone smartphone. Make sure that the charging station and the smartphone are in the same WiFi range.
2. Turn on the Wi-Fi router, make sure that the router can connect to the Internet. 3.
3. Turn on the smartphone‘s WiFi, connect the smartphone to the router via WiFi, and make sure that the terminal can access the Internet via the router.
4. Install the „esptouch“ APP on your smartphone.
   esptouch for iOS:https://apps.apple.com/app/espressif- esptouch/id1071176700

esptouch for Android:https://play.google.com/store/apps/details?id=com.
Open the EspTouch app, select „EspTouch“ (not „EspTouch V2“) from the list and grant the app the location authorization. Now enter the password for the currently connected WiFi network and press „Confirm“ or „Start“ to perform the WiFi configuration.

5. Press and rotate to reset the emergency stop button three times in succession until the four indicator lights illuminate in a cycle corresponding to the running lamp mode. At the same time, the LCD screen changes to the WLAN configuration page. Click the „CONFIRM“ button of the APP on the smartphone (Fig.1).
6. When all the indicator lights flash once in a second, it indicates that the charging station‘s Wi-Fi configuration is completed. At the same time, the LCD screen will display „Successful“ and the name and password of the WLAN SSID
   Note: If the configuration fails, please set the „Multicast“ option in the „EspTouch“ app and repeat the process. Note: The charging station supports only 2.4GHz wireless networks. Please make sure that your Wi-Fi network operates in the 2.4GHz band.
   Note: The IP address of the charging station is negotiated via DHCP. Manual setting is not possible.

RJ-45 connection

The charging station has an RJ-45 connector that can be used for Ethernet and RS-485. Note the pinout for the RJ-45 connector below. Open the cap of the RJ-45 connector and plug in a
CAT5e cable or better.
Pinout:

Note: A waterproof housing for an RJ-45 cable is optionally available.
Note: The IP address of the charging station is negotiated via DHCP. Manual setting is not possible.

RFID cards

The charging station is supplied with two RFID cards for offline mode with which charging
processes can be started and stopped. RFID cards for online mode with an OCPP backend are optionally available and have an identification number printed on the card, which must be registered in the OCPP backend. RFID cards for online mode can be personalized by the unique identification number.

Programming of RFID cards (Offline mode)

To program additional RFID cards for offline mode, proceed as follows.

1. Switch on the charging station and disconnect the cable from the vehicle.
2. Press the emergency stop button.
3. Hold the new RFID card (offline mode) against the RFID reader for at least 10 seconds. The new RFID card is now programmed for the EV charging station.

Change charging mode

By default, the charging process is controlled with RFID cards (see section Charging the vehicle). To start the charging process directly after inserting the type 2 plug, the charging mode
of the charging station must be changed. Proceed as follows:

1. Switch on the charging station and disconnect the cable from the vehicle.
2. Hold the programmed RFID card against the RFID reader for at least 10 seconds. Switching the charging mode is signaled by the flashing or solid illumination of the Charging (orange) and Fault (red) LEDs.

Emergency stop button

Only press the emergency stop button during a charging process in an emergency. Charging will stop immediately.
Note: Do not press the emergency stop button to end a normal charging process.

Connect with an OCPP backend

The charging station supports OCPP (Open Charge Point Protocol) JSON 1.6 for communication between charging stations and a central management system (backend). Before using OCPP, the endpoint URL must be programmed into the charging station. To do this, please send us the endpoint URL to be programmed, as well as the serial number of the charging station, which you will find in the display of the charging station, by email to ocpp@em2go.de.
Note: The endpoint URL must start with ws:// or wss://. It may take up to 24 hours for the endpoint URL to be programmed into the charging station and for the charging station to connect to the central management system. Make sure that the charging station is switched on and connected to the Internet during this time.
RS-485 The charging station can be externally programmed, controlled and monitored via RS-485 using AT commands. For the assignment, see the section RJ-45 connection. All commands are terminated with (carriage return).
Note: For the connection via RS-485, bias and terminating resistors may be required depending on the cable length. These are not necessary for short cable lengths. If there are high ground potential differences between the charging station and the
RS-485 transmitter, it is recommended to use a ground cable.

Commands are sent in the format AT+ or AT+=. For each command received, the charging station sends a response.
