Overview

The charging station features a front panel with a display showing charging status symbols. It comes in various configurations for different output power and numbers of outlets. Refer to the top of the charging station for model information.

Status Symbols

The charging station uses various symbols to indicate its status:

• Solid Red: Alarm active, likely a fuse trip. Check the technical box and reset the fuse.
• Solid Red (flashing once): Outlet has a temporary fault (e.g., authentication time limit reached, PP-signal error, or cable lock issue).
• Solid Blue: Charging station connected to cloud backend (displayed during boot-up for 5 seconds).
• Flashing Blue: Charging station failed to connect to cloud backend during start-up.
• Solid Green (RFID): Waiting for RFID tag.
• Flashing Yellow: Authentication in progress.
• Flashing Green: RFID tag approved, charging will start.
• Flashing Red (once): RFID tag access denied.
• Solid Green (RFID/Open): Available and ready for charging.
• Flashing Green (RFID/Open): Waiting for cable connection or authentication.
• Solid Blue (RFID/Open): Vehicle connected but not charging.
• Flashing Blue (RFID/Open): Charging in progress.

If no symbols are active, the station may be inactive, restarting, or deactivated for maintenance.

Charging the Vehicle

The charging station supports two authentication modes:

• Open Access: Charging starts immediately upon vehicle connection.
• RFID Access: Charging requires authentication with an RFID tag. Some operators may offer additional authentication methods like mobile apps.

To connect to the vehicle: Connect the charging cable to the vehicle.

To start charging with open access: Connect the vehicle, and charging begins.

To start charging with RFID access: Connect the vehicle, present an RFID tag to the reader, and charging will commence after successful authentication.

Note: Ensure compatibility if using non-CTEK RFID tags (supported standard: ISO1443A/Mifare).

Installation

Installation must be performed by an accredited electrician, following all local safety regulations and the instructions in this document.

Safety Precautions:

• Read and obey all instructions before installation and operation.
• Do not use adaptors or conversion adapters.
• The charging station does not have ventilated charging.
• Ensure cables are securely connected.
• Installation is recommended for two persons.
• Use safety shoes during installation.

Tools Required:

• 4 mm drill bit
• RFID tag (if used)
• Computer/Laptop with USB driver (Linux, OSX, or Windows 10)
• Mini-USB cable

Optional Equipment:

• Pole mount kits for 60 mm poles or for two boxes.

To Check Before Installation:

• Avoid direct sunlight to prevent overheating and reduced visibility.
• Decide on indoor or outdoor installation. For outdoor use, route cables from below to prevent water ingress.
• Ensure the wall material can support the charging station's weight (up to 24 kg).
• For pole installation, refer to the pole mount kit manual.

To Install the Charging Station on a Wall:

1. Locate the four screw holes in the back cover.
2. Drill four holes in the wall aligned with the back cover holes.
3. Unlock and open the technical box with the key.
4. Remove the protection cover.
5. Install the charging station using rubber gaskets, washers, and M8 screws. Ensure rubber gaskets are used to prevent water leaks.
6. Ensure the station is firmly installed.
7. Cover any open holes with silicon or rubber gaskets for water protection.

To Install the Charging Station on a Pole:

Refer to the manual for the pole mount kit.

To Do the Cable Installation:

1. Ensure the power is off.
2. Dimension the cable installation (A) appropriately for the charging station.
3. Drill holes in the unit for power and network cables if installing from below or the back. Ensure no internal components are damaged.
4. Install cable glands to protect the unit from dust and water. Note the supported cable dimensions.
5. For top installation, use the larger hole (M25) for the power cable and the smaller hole (M12) for the network cable.
6. Ensure the protected ground wire is longer than other wires.
7. Strip wires to 18-20 mm. The cross-sectional area should not exceed 16 mm².
8. Connect supply wires to the terminal blocks, ensuring proper connection.

To Install the Power Cable:

1. Pull the power cable through the cable gland.
2. Ensure the protected ground wire is longer than other wires.
3. Strip wires to 18-20 mm. The cross-sectional area should not exceed 16 mm².
4. Connect the supply wires to the terminal blocks.

To Install the Network Cable and 3G-Modem (Optional):

• Enclose the network cable with insulation for electrical safety.
• For firewall configurations, open DNS (port 53) and https/wss (port 443), and FTP for remote firmware upgrades.
• Use Cat5 or better Ethernet cable, connecting to the RJ45 connector on the control board. The activity LED will activate upon connection.
• For 3G connection, install an activated SIM card with the PIN disabled and a minimum 2 GB/month subscription. Ensure the antenna cable is attached at both ends. Some operators may pre-install the SIM card.

To Finish the Installation:

1. Install the protection cover.
2. Close and lock the technical box with the key.
3. Place the cover on the key lock.
4. Turn on the power from the distribution panel. Allow 1-2 minutes for the charger to start.
5. Verify the green connector symbol on the front panel activates.
