EO Mini Pro 3 Installation Guide

Before you start

1. Register with EO as an installer and complete the necessary induction modules.
   Failure to register with the EO academy may invalidate the customer’s warranty.

2. Ensure you have access to a mobile device that can connect to Wi-Fi, and appropriately sized cable glands, based on cable sizing.

3. Find the Installer Details label within the rear housing (see below) and take a clear photo where you can read the text clearly. You will need to refer to this later.

Charger installation

1. Remove all packaging.
In the box:
A) Fascia – this is the last component to fit
B) Centre section containing the charger socket and main electrical components
C) Rear housing containing the electronics, including the Wi-Fi and GSM modems, make sure you have a clear photo of the Installer Details label on the inside wall of the main housing (see image C) 2. Place the base of the EO Mini Pro 3 in the installation location and make sure the surface is flat and level.
3. Level the EO Mini Pro 3 base and mark the position of the four holes.
4. Take the EO Mini Pro 3 base away and drill the four holes in the mounting surface. 5. Attach the EO Mini Pro 3 base to the wall using the four screws provided. Make sure the charger is secure and flush against the wall. Use packing washers if necessary for a flush fit.
6. Strip and prepare the power cable and feed into the pre-made hole and stuffing gland, using an appropriately sized gland (25mm gland provided).

When connecting CT clamps for load management, there is a four-pin connector block in the lower right of the unit (see right). Ensure this is firmly seated before moving on.
IMPORTANT: If a separate CT wiring label is supplied with the charger, follow the instructions on this label. It is specific to the charger you are installing and supersedes this guide.

Wire designations for load management

Connector Number| CT Assignment| CT Wiring Colour| Function
---|---|---|---
1| CT1B| Red| ALM
2| CT1A| White| ALM

The CT clamps supplied have a red and white wire attached to them.
The CT for load management should be connected to CT1. Connect the white wire to position 2 and the red wire to position 1.
Make sure to orientate the CT clamps correctly when connecting them to the supply cable.
The clamps have an arrow which should be orientated with the current flow, which is the flow from the supply.
8. Take a photo of the Installer Details label if you haven’t already. You will need this information to configure the charger once the unit is assembled.
9. Before closing the charger case, check that the PCB tethering lead is plugged in and connects both front and rear PCB boards together, as shown on the next page.

Make sure the lead is connected to the right-hand male connector of the rear case, as below: 10. With all cables securely connected, close the Mini Pro 3 cases together, making sure no internal cabling is trapped, and secure the housings together with the four hex bolts and washers.
11. Do not attach the fascia to the EO Mini Pro 3 until all testing is done. Complete all testing before closing the unit.

Software setup

1. Power up the charger.
2. You will see a hotspot with the name eo-xxxxxxxxxxxxxx – it may take a couple of minutes to appear. The hotspot expires after 10 minutes if no connection is made. You must power the charger down and back up again to reactivate the hotspot.
3. Use a laptop or mobile device to search for the Wi-Fi hotspot and join it, using the credentials on the Installer Details label – you should be able to see these in the photo you took earlier of the label. NOTE: For Windows OS, you may be limited to entering eight characters into the password field. To enable more characters, click Connect using a security key instead.
4. Once connected to the hotspot, open your device’s web browser.
5. In the address bar, type 10.10.10.1 – your browser may warn you with a security message. Accept it and proceed.
6. You should now see the charge point User Interface [UI] login page.
7. Enter the UI credentials from the Installer Details label.
8. Confirm charger settings.

• Check and set the time in your location
• Enter your installer details
• Enter the charger current limit. This is set at 32A, but you may want to reduce this if site capacity is not adequate
• Check and amend the phase selection and connection where applicable
• Make sure Tilt/Bump Detection is enabled
• Make sure the Bump Acceleration is set to 2g and Tilt Angle to 10°
• Tap Save Tilt + Calibrate to confirm if you have changed any of these values
• A CT clamp is provided for load management. Select External Metering, set it to CT clamp and save your settings (see first image on the next page)
• If an external CT clamp has been fitted, enable the option, enter the CT rating and set the Type to Site
• Make sure your CT clamp is connected at the outgoing live cable, then click Save + Calibrate

CT Types
Source: An external source of energy.
Site: Boundary point into a property which will contain the charger usage within it.
Load: An external load to the charger that does not contain the charger usage.
Load Management
Where a CT clamp is fitted you can set parameters for load management on the Load Balancing page.

Load balancing is switched off by default so slide the toggle to allow inputs.

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 recommend referring to your site load tests for more accurate inputs in these fields.
3. Select Dynamic from the Load Balancing Mode menu and save your settings.
4. Set Load Balancing Minimum Change to 1A.
5. Set the Safety Margin to the appropriate values, for example, 100A and 10A.
6. Save your settings.

Smart Charging

In accordance with UK regulations, all chargers are supplied with a Smart Charging profile enabled. Customers can log in to the charging station using their EV user account to view their transaction history and modify their default charging schedules and Randomised Delay settings.

If the charger will be used with the Hive app:
Disable the toggle beneath Default Profile and set the Max Delay (beneath Randomised Delay) to 0. These will be overridden by the Hive app.
If the charger will be used as a non-smart charger, without the Hive app:
Set the Default Profile to suit the customer’s requirements. Otherwise, they will only be able to charge outside of the periods set by the factory.
Set Max Delay to 600s and check all settings with the customer.
Otherwise, the charger may not work as they expect.

NOTE: Any Smart Charging settings you configure for non-smart operation may impact testing or demonstration of the device to the user. After you have confirmed these settings in line with the end user’s requirements, you may need to temporarily disable the Smart Charging profile (using the toggle under Default Profile) to carry out any test or demonstration.
To re-enable it after your testing / demonstration is complete please follow the initial hotspot connection process and navigate back to the Default Profile section.

Randomised Delay

There is a risk of overloading the grid if lots of people start or stop charging their EV at the same time. To avoid this, all EV chargers now have a Randomised Delay feature. This means that there will be a random delay of up to 10 minutes when customers start or stop charging, which will help the grid stay balanced.
This setting is a legal requirement so it can’t be switched off, but it doesn’t apply to customers who have their own energy generation (such as wind or solar) and are using their own excess energy. EV chargers that provide Demand Side Response are also exempt.
The default setting is 600 seconds. This means that when the customer plugs their EV into the charger, it will start charging anywhere between immediately and 10 minutes later.
If it is set to zero, the charger will always try to start charging as soon as an EV is plugged in.

IMPORTANT: NEVER give a customer your installer access credentials as it could cause damage and be a health and safety risk. Customers can amend their settings with their own login details, which are provided on their own access label. The functions they can access are limited for safety reasons. They can find more details in their user guide.

PEN fault detection

Hive’s EO Mini Pro 3 models HIVE-EV-01 and HIVE-EV-02 have built-in Protective Multiple Earth (PEN) fault detection and no configuration is needed.

GSM – Hive SIM

For units that are GSM-enabled with a Hive 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. Do not change these settings .

3. Modem Status messages:
   • SIM Status: This shows the charger can see the SIM and communicate with it.
   • IP: Displays the IP address assigned by the network provider.
   • PING Test: Displays a successful communication ping to the back office.
   • RSSI: Signal strength.

4. Connection via GSM will not occur unless the Wi-Fi hotspot connection has timed out or closed so disconnect from the hotspot and reboot the charger.

Physical EO Mini Pro 3 installation is now complete. The customer can now log in to the Hive App to complete setup of the charger. If the customer has not received a charger PIN from Hive then please follow the customer registration steps which follow.
NOTE: If you are unable to connect the charger via GSM, please contact Hive Support on +44 (0)333 202 1054

Customer registration

The customer needs to be registered with Hive to receive the PIN that is required to add their EO Mini Pro 3 charger to the Hive App. You can complete this by:

• Going to hivehome.com/ev-charging-retail or scanning the QR code on the Installer Details label
• Entering their details on the registration form
• Adding their Charger PIN, which they’ll receive by email from Hive

NOTE: If you are installing this device in a new build property or somewhere else where you do not have the customer’s details, the registration process allows you to input information so Hive can onboard the customer later.
After completing the installation and configuration of the charger, it may update to the latest firmware. This may take a few minutes.
