6. Dip Switch
   The Dip Switch located on the PCB behind the front panel can be used to set a hard current limit on the charger. A switch in the up position is OFF, while a down position is ON.

CT CLAMP INSTALLATION

CT Clamps need to be installed on the grid side of the main switch board.

Critical Installation Note:
The CT Clamps have a direction requirement. The Clamps need to be installed so that the arrows are pointing towards the main switch board, i.e. Away from the grid.
Failure to correctly install the CT clamps will require a return to site.

SINGLE PHASE CT INSTALLATION

The arrow on the CT must be pointing towards the Main Board and away from the grid supply

THREE PHASE CT INSTALLATION

The arrow on the CT must be pointing towards the Main Board and away from the grid supply

CT CLAMP INSTALLATION AND WIRING
Run the CT clamp wires through the grey gland/hole located at the bottom of the charger. Wire into terminal block as indicated in the picture below.
For Single Phase, use the first two ports on the right.

INTERNET CONNECTION AND CHARGER INSTALLATION

1. Connect the charger to the internet
   The charger can be connected via ethernet or WIFI. Ethernet is recommended for stability.
   Connect the ethernet cable to the WAN port behind the front panel.

2. Reconnect the communication cable to the PCB on the front panel, tighten the screws to secure the front panel.

Tighten the screws with a torque of 0.2-0.5 Nm. Do not over-tighten.

WI-FI
Wi-Fi setup will be shown later in the next page. It is not recommended in commercial installations or apartments. Unstable/weak WI-FI connection may cause undesired operational issues.

WEB-INTERFACE ACCESS AND WIFI CONNECTION

1. Find the chargers’ local hotspot using laptop or smart device.
   Search for the charger’s hotspot like you would for any Wi-Fi network. This hotspot will have the following SSID: AP_IOC- **
   (if needed you can find the full SSID on the sticker side of the charger)
   The password for this Hotspot is: IOC12345

2. Navigate to the web-interface of the Ocular Charger.
   Open a web browser (Chrome, Safari, Edge) and search: 192.168.10.1:8900 The web interface will ask for Username and Password:

   • Username : install
   • Password : Evcharging123
     After entering the username and password, the Ocular web-interface will load.

3. (Optional): Set up WIFI configuration (not needed if ethernet is used)

   • Navigate to the Network tab (see picture on below).
   • Click the “Scan” button to start scanning for available WiFi network.
   • Use the dropdown list to select the required network, enter the password.
   • Click Submit then Reboot (top right-hand corner) to apply changes.
   • You will then need to log back in to the web-interface to continue configuration.

CHARGER CONFIGURATION – ACCESSING THE ADVANCED SETTINGS

Do not change settings other than outlined below as this may affect operations.

1. Log in to the web-interface of the charger. (Refer to page 13).
2. Click on the Balance tab, and then click on “Advanced Settings”.
3. A new page will open that shows the Balance and CT clamp settings.

CHARGER CONFIGURATION – CT CLAMP SET UP

1. Scroll down the page until you can see the settings boxes for HUB1 and Grid Current.
2. Ensure HUB1 is switched on (Blue indicator).
3. Configure HUB1 settings as in the pictures below. Note the differences between the Single Phase and 3 Phase setups.
   • A. Single Phase – Turn off the 3-Phase switch, set CT1 position to “Main”, ensure ratio is set to 2000:1 and set Phase to “L1”.
   • B. Three Phase – Turn on the 3-Phase switch, set CT1 position to “Main”, ensure ratio is set to 2000:1 and set Phase to “L1”.

CHARGER CONFIGURATION – GRID SUPPLY SET UP

1. Set the Rated Current and Safe Current.
   Rated Current: This is the maximum current that the main MCB can handle. Safe Current: This is the safe current reserved to prevent the circuit from overloading. The actual available current for the charger is:
   Actual available current = rated current – safe current – load current

2. In the top right hand corner of the screen, click “Submit” and then “Reboot”.

3. The charger will reboot and then can be used.

Example
A 80Amp Main Switch Board should have:
Rated Current – 800
