• Do not use or stop using the charger if it is defective, appears cracked, frayed, broken or otherwise damaged, or fails to operate.
• Do not attempt to open, disassemble, repair, tamper with, or modify the charger. The charger is not user serviceable. Contact iocharger or authorized service provider for any  repairs.
• Do not touch the charger sockets with sharp metallic objects, such as wire, tools or needles. Do not put fingers into the charger sockets.
• Do not use this charger if the EV charging cable is frayed, has broken insulation, or displays any other indication of damage.
• Do not use this charger if the enclosure or the EV charging connector is broken, cracked, open, or shows any other indication of damage.
• Ferrules must be used to ensure warranty is valid

CAUTIONS

• The charger should be installed only by a qualified approved technician.
• Make sure that the materials used and the installation procedures follow local building codes and safety standards.
• Incorrect installation and testing of the charger could potentially damage either the vehicle’s Battery and/or the charger itself. Any resulting damage is excluded from the warranty  for both the vehicle and the charger.
• Do not operate the charger in temperatures outside its operating range of -30°C to +50 °C.
• Ensure that the EV charging cable is positioned properly to the charging sockets. Do not use cleaning solvents to clean any of the charger’s components.

NOTES BEFORE INSTALLATION

BOX CONTENTS

WALL MOUNTING AND WIRING

1. Remove the backplate from the charger by sliding it down. Mount the backplate to the wall with the included screws.
2. Connect the cable through the bottom of the junction box. Ensure conduit is connected to the bottom of the power box.
3. Conduit can come out the bottom of the charger, or be passed through the wall to remain hidden.
   Connect the incoming supply to the terminals.
   In Australia only the TN network is used, as shown on the label on the back plate
   

Ferrule crimps must be used to ensure warranty is valid

INTERNET CONNECTION AND CHARGER MOUNTING

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 top port.

2. Install the charger to the backplate. Line up the mounting screws and then slide the charger down to lock the connection.

3. Fix the charger to the backplate at the bottom of the charger with the included screw.
   

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

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 & 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.

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
     

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 11).
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”.

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
• Safe Current – 80 (10% safety is recommended as a minimum. This can be higher if required. The charger will stop charging completely if it sees load above 720 which is 72 Amps.)
• Please note, the scale is 0.1A i.e. 1 Amp is a value of 10

INSTALLATION VERIFICATION

1. Verify all cabling is wired properly.

2.  Verify that the CT clamps are installed in the correct direction.

3.  Take a photo of the CT clamp installation at the main board as a record. This will help any future troubleshooting.

4. Turn on the charger and check for any errors on the screen.

5.  Verify that the charger is connected to the Ocular Server by checking Icons on charger screen.
   A. If the charger is showing (Server Error) then the charger will not function and this will likely require a return to site. If the screen is not showing , check the wifi/ethernet connection. If problem persists, contact ocular support on 1300 912 650.

6.  Show customer how to set up the IQ Solar App. (See next page)

7. Test charging with simulator or electric vehicle.

CONNECT CHARGER TO OCULAR SMART HOME APP

1.  Search “Ocular Smart Home” or Ocular Charging” on the google play or apple app store.
2.  Download, install, and launch the app.
3. Navigate to the Group page and click “Add Station”.
4. Enter the charger serial number. This can be found on a sticker on the side of the charger. It starts with AW and will look like AW1234567890.
5. Click “Add”. The charger should now show up in the group page.
6. Navigate to the “Energy” tab.
7. Enter the gateway serial number. This is the same as the charger serial number but with M_ in front of it. It will look like M_AW1234567890.
8. Click “Add” The energy tab should now show your solar and charger activity.
9.  The charger can now be used.

APPENDIX C – CT CLAMP SPECIFICATIONS

Prior to setting up the CT clamps, please ensure that you have the correct CT and CT Ratio setup.
Only use CT clamps provided by Ocular – The wrong CT clamps will cause a misreading and void warranty. If you must use your own CT please speak to Ocular and confirm suitability.
The Rate Transformation Ratio must be 2000:1 or the CT clamps will generate incorrect readings.
