RE-REQUISITES

For installation of the EO Mini Pro 3 you will require the following:

1. Preferably a fully charged mobile device.
2. Wi-Fi analyzer mobile app of your choice (refer to section 13.0).
3. Make sure the customer provides a suitable internet connection; either Wi-Fi or LAN.
4. Make sure the customer is available during the installation and provides their Wi-Fi SSID so the Wi-Fi integrity tests can be carried out.
5. Provide appropriate cable glands based on your cable sizing and if using Ethernet cable.
6. Utilize a suitably sized hole cutter where additional Ethernet cable entry is required.
7. Locate the “Installer Access Label”.

2.1 RESIDENTIAL WI-FI
To help in finding the best mounting location for the charger, we recommended that the integrity of the Wi-Fi signal is checked before fitting the device in its location.
Weak or unstable Wi-Fi signals may result in an unreliable or failed installation of the EO Miniport 3. To check that the Wi-Fi signal is suitable please complete the following steps:
Utilize a suitable Wi-Fi analyzer mobile device app to verify signal stability, strength, and interference levels are adequate. Apps are available for both Android and iOS devices.
Using a Wi-Fi analyzer app, stand at the intended charger installation location and measure the RSSI signal to the client’s Wi-Fi router. The ideal value should be no greater than -60dB. Where Wi-Fi integrity is not suitable, a few options exist:

1. Install a 2.4gHz Wi-Fi booster.
2. Use the hard-wired Ethernet option.
3. Re-locate the Wi-Fi router.

12. Attaching the fascia to the EO Mini Pro 3 should be carried out after all testing is complete.

CHARGER INITIALISATION STEPS

The charger will require setting up before handing over to the homeowner.
The steps to follow will be:

1. Powering up the charger.
2. Locate the installer “Access Label”.
3. Using a mobile device, connect to the charger hotspot.
4. Accessing the charger interface via your mobile device web browser.
5. Logging into the charger user interface using credentials printed on the “Access Label”.
6. Applying a few basic settings such as property supply current, circuit voltage, charger power output requirement including Load management if required and smart charging.

CHARGER SOFTWARE SETUP

1. Power up the charger.
2. A hot spot will be displayed [only active for 10 minutes]. Example eo-01234567891011
3. Use your Laptop or mobile device to, search for the Wi-Fi hotspot and join it [joining credentials are shown on the “Access Label”].
4. Once connected to the hotspot, open up your device’s web browser.
5. In the browser address bar type 10.10.10.1 [your browser may warn you with a security message. Accept and proceed].
6. You are now presented by the charge point “User Interface” [UI] login page.
7. Enter the UI credentials. The credentials can be found on the “Installer Access Label” in the packaging or stuck to the charger.

SMART CHARGING

Due to UK regulations chargers will, by default, be supplied with a smart charging profile enabled.

The default profile will be automatically overridden by the “EO Charging” app during the product registration process carried out by the homeowner.
If the charger is to be operated as a non-smart charger and not to be used with the “EO Charging” app, you will need to review this profile to suit the homeowner’s requirements.
This is important as the charge sessions will only operate outside of the charging periods set by the factory. Refer to the above image.
** You must consult with the homeowner on what setting they wish to have applied, or the charger may not operate as expected.
N o te: Smart charging settings will influence your final testing using EV-dedicated test equipment. You will have to disable the Smart Charging profile temporarily and re-enable it after your tests are completed. Follow the initial hotspot connection process as explained in section 6.0 to re- enable the profile.
6.1 RANDOMISED DELAY
This setting needs to be explained to the customer as this will have an impact on how their charging session operates.
To explain this feature further: the default setting is 600s which is equal to 10 minutes.
When a vehicle connects to the charger, the charger will randomly offer power to a vehicle anywhere between zero and 10 minutes based on the example shown.
If the figure is set to zero, the charger will always try and offer power to a connected vehicle immediately when plugged in.
If your customer complains of charging sessions being delayed when their vehicle is plugged in, it could well be due to this “Random Delay” setting.;
Important: The homeowner, using their dedicated access credentials, will have to access the charger UI and amend the value. Under no circumstances should you offer your “installer” access credentials to the homeowner.
** The homeowner is provided with their own access label which offers limited functions for safety purposes.

INSTALLER

Once logged in select the “Installer” section.

Here you will need to input the following:

1. Check and set the time according to your location.
2. Enter the charger current limit. By default, this is set at 32A however you may want to reduce this if site capacity is low.
3. Enter your name, company and email address.
4. Make sure the “Tilt/Bump Detection” is enabled, set the acceleration and tilt angle to 1 degree and click the save and calibrate button.
5. Check and amend the phase selection and connection where applicable.
6. If an external CT clamp has been fitted, enable the option and enter the CT rating and set the “Type” to “Site”
7. Making sure your CT clamp is connected at the incomer, click “Save + Calibrate”.5. Check and amend the phase selection and connection where applicable.
8. If an external CT clamp has been fitted, enable the option and enter the CT rating and set the “Type” to “Site”
9. Making sure your CT clamp is connected at the incomer, click “Save + Calibrate”.

CT TYPES EXPLAINED:
Source: An external source that is pushing energy into the site.
Site: Boundary point into a property which will contain the charger usage within it.
Load: An external load to the charger which will not contain the charger usage.

LOAD MANAGEMENT

If you have installed a CT clamp for load management, follow point 6 below or disconnect from the charger hotspot and reboot the device

1. For charger load management, select the “Load” page. Where a CT clamp is fitted you can set parameters for load management.

The setting is turned off by default, therefore, slide the toggle on which allows inputs to be made.

1. Set the site limit value. This is the incoming supply value to the property. e.g. 60 or 100 Amps.
2. Input a load balancing margin. This will be a safety value in amps, for example, you may wish to set a safety margin of 50A on a 60A incoming supply. We would recommend referring to your site load tests for more accurate inputs in these fields.
3. Select “Dynamic” from the load balancing mode section and save your settings.
4. Set load balancing minimum change to 1A.
5. Set the “Site limit” and “Safety margin” to the appropriate values, for example, 100A and 10A.
6. Save your settings.

GSM – EO SIM

Guidance for units which are GSM-enabled with an EO SIM.

1. Select the “Network” page from the left hand menu.

2. At the bottom of the page, you will find a “Modem” section showing SIM status details. These settings are not to be changed unless advised by EO Support.

PEN FAULT DETECTION

The EO Mini Pro 3 PME variant, EM301-DCL-PME, has inbuilt PEN fault detection. There are no configuration options required for this feature and it continually operates whilst the unit is powered on.
If the Mini Pro 3 is fitted with the PEN Fault Detection system (model designator -PME), then the Mini Pro 3 will detect errors in the incoming grid connection. If a PEN fault is detected then the vehicle will be fully isolated from the charging station and the LED shall illuminate solid RED. It shall not be possible to charge a vehicle in this condition. In order to restart charging:

• The vehicle must be unplugged from the charging station.
• The Mini Pro 3 must be power cycled or remotely reset.
•  If the LED remains RED then the grid connection is still not within the defined safety limits and an installer must be contacted to inspect the incoming supply. If the normal pulsing Blue LED is shown then the system is safe to use.

**** For PME variants, please make sure these are ordered at the point of purchase as cannot be retrofitted.

WI-FI INTEGRITY & STABILTY

**** Wi-Fi signal integrity: Wi-Fi signal strength depends on a variety of factors, such as how far you are from the router and even the materials of the walls around you. The closer you are to the router, the better. While 2.4ghz connections broadcast further, they might have interference issues. Thicker walls made of denser materials (like concrete) will block a Wi-Fi signal. A weaker signal, on the other hand, leads to, dropouts, unreliability and (in some cases) total disconnection. Measured in dBm [decibel milliwatts] More detailed explanation on testing the integrity of Wi-Fi is provided in our online Academy training modules.
