Fix the charger and backplate with screw

INTERNET CONNECTION

Ethernet – Commercial, Apartment or Home installations
Please connect the ethernet cable to the WAN port this should connect automatically to the internet if there’s no IT restrictions,
( if static IP address is required please refer to the Ocular Configuration manual) (See Ocular or local supplier for manual)

Wi-Fi
(Not recommend in commercial installations or apartments.) Please note: unstable/weak WI-FI connection may cause undesired operational issues. Please call installer if Wi-fi signal is insufficient.

Wi-Fi Connection Guide

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

Step 1: Find the chargers’ local hotspot
This hot spot will have the following SSID: IOC – 2.4GHz – **
The password for this Hotspot is: IOC12345

Step 2: Navigate to the web-interface of the Ocular Charger
After being connected to the Hotspot, open Microsoft Edge or Google
Chrome and navigate to: 192.168.10.1:8900
The web interface will ask for Username and Password, the information is:
Username : install
Password : installer123

Step 3: Navigate to the Network and set up WIFI configuration
Ocular charger support connection via WiFi. Simply press the “Scan”
button to start scanning for available WiFi network

After this, press the down arrow in the drop list to see all the available WiFi networks

Choose the Wi-Fi SSID that you prefer, and then input the Wi-Fi Password

If Static IP address is required, simply disable DHCP under WiFi section and put in the Static IP Address for the device

Step 4: Submit then reboot the charger to apply changes

Residential/Home Wiring

Regarding the installation of the Ocular IQ Solar, each charger will need a power connection and an additional internet connection to allow smart charging with energy tracking , smart control and load management.

Power connection
Internet connection (required for smart functions)

Regarding the power connection of the chargers, each charger will have its own designated circuit from the distribution board as per required in Appendix P, AS 3000:2018 Australia Standard for EV charging stations. We recommend 40A type A RCBO for the IQ Solar to avoid nuisance tripping Regarding the Internet connection, we recommend running an Ethernet cable from the communication infrastructure comms cabinet to the charger for internet connection. Wi fi can be used when the signal is strong. Above 3 bars

CT CLAMP INSTALLATION & WIRING

Please run the CT clamp wires through the grey gland/hole located at the bottom of the charger.
Please connect internally following this diagram:
| CT1| CT2| CT3
---|---|---|---
RED| Pi| P2| P3
BLACK| N1| N2| N3

CT CLAMP SPEC REQUIREMENTS

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.

Step 2: Set the address to 254.
Step 3: Turn on the 3-Phase switch.
Step 4: Set the CT1 position to “Main.” Set the ratio to 2000:1 and set the phase to default to “L1.”

THREE-PHASE CT INSTALL

CT CLAMP CONFIGURATION

Grid Current (please note scale is 0.1A so 1 Amp is a value of 10)

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 charging station is calculated as follows: Actual available current = Rated current – Safe current – Load current.
Limit Total Charger Current: This is the actual available current in the circuit, which is equal to the rated current plus the solar power generation current. The default maximum value is usually 65535. This should not be changed.

For example, a 80Amp distribution board should have
Rated Current – 800
Safe Current –80 (10% safety is recommended as a minimum This can be higher is required. The charger will load manage and stop charging completely if it sees load above 720 which is 72 Amps.)

Data Reporting Interval
Idle：Interval for reporting status when idle (Default is 30 seconds)
Charging：Interval for reporting status when charging (Default is 30 seconds)

VERIFY THE INSTALLATION

Verify the power cables are wired properly
Close the upstream RCD to power on the charger unit, and you should see the LED lights sequentially illuminate blue.
If the LED red light illuminates or flashes, refer to the troubleshooting table.
Check on the screen display whether internet is available and the back office is connected, refer to page 17-19.
Verify the settings on the backend (specifically energy management server) match settings in image to right
Test the live charging process with simulator or electric vehicle if the installation is completely verified.

Provide these details to the charger owner to login to the back end of the charger
