Installation

1. Create a new account in the GARO Connect app.
2. Follow the instructions on the screen.
3. Log on to the GARO Connect app with the provided credentials.
4. Select Manage Locations.
5. Choose location.
   • NOTE It is recommended to change the name on the default location. Preferably, the name should specify the physical place of the unit, including address and coordinates.
   • In this example, the location is called the Main office. To change the name of a location, click the location and choose Edit location.
6. Select Invite Installer.
   • NOTE The installer can create and install charging stations once invited with the installation code from the owner.
7. Generate an installation code. An e-mail can be generated to the installer through the GARO Connect app. This is not mandatory, any communication channel is fine.
   • A message to the installer concerning the location or installation can be tied to the location, for example, the Wi-Fi credentials if a local Wi-Fi is to be used.

Charger settings

• The features available under Charger settings (owner) are not mandatory.

Charger settings

• The settings for each charging station can be changed. Click on the applicable charging station, then Charger Settings, and follow the instructions in the app.

Enable charging station

• Under Manage charging stations > Charging Settings, each charging station can be enabled/disabled by the owner. If the charging station is disabled, the charging station cannot be used.

Charging station access

• Each charging station can be set to free use (default). This enables access for everybody. If the EV driver identifies before connecting to the EV, the charging transaction is registered to the EV driver.
• At delivery, the free use is enabled by default. The charging station is at that time not set up for access control. Free use can be used, even if the charging station has defined EV drivers, those rights can be seen as “overridden” by the free use.

Invite drivers

• The owner can invite EV drivers from the app. Click Charger Settings, select Users, and follow the instructions in the GARO Connect app. EV drivers can be added individually or through an EV driver group.
• NOTE If the EV driver does not have a GARO Connect account, an invitation email will be sent to that EV driver.
• Create a charger group for the charging stations
• A charger group is used to manage access control of several charging stations, for example, “Northern parking”. Access control can be done both on an individual level and on a group level.
• It is not mandatory to create charger groups during the installation process. It is possible to create charger groups at a later time.

Cluster EV drivers

• EV drivers can be managed in clusters called EV driver groups, which makes access management easier. EV driver groups are related to the organization, which means they can be used in several locations within an organization.
• The organization is a good tool when administrating several locations.

Advanced owner tools

• Additional owners can be added and removed to a location and organization. However, an organization and location must always have at least 1 owner.
• A location can also be handed over to another owner (for example “sold to”).
• The owner is normally given default access to use the charging stations of the location.

INSTALLER

• The installer is a certified installer or acts on behalf of a certified installer. The installer is hired by the owner to perform the electrical steps of the installation of the charging station(s) that are connected to a location.
• To access a location for installation, the owner of the location creates/generates an installation code. The installation code is a 12-letter code that works like a key to the location.
• The code can be handed over to an installer by email, paper, or any other media.
• The installer must have the code to start an installation.
• If a new installation code is generated by the owner, the old one is invalid, like a key.
• The installation process of the installer is described in the illustration below. For a full instruction, refer to To prepare the installation (installer)
• NOTE When a new installation is started, the installer can act as a temporary owner and then hand over ownership of the product(s) to the owner.

1. Enter the installation code in the GARO Connect app. The installation code is related to a location.
2. Select the location that the owner has set up.
3. Create or choose a charging station.
4. Perform the physical installation. Refer to 4 Installation
5. Connect the selected, logical charging station to a physical installation bracket, by scanning the IB QR code.
6. Set up the internet connection for the charging station(s).
7. Perform necessary firmware updates.
   • NOTE Updating using a modem as internet access takes a long time.
8. Perform the configuration settings.
9. Create connection groups and install load interfaces (if needed).
10. Perform test charging to make sure that the charging station(s) operate correctly.
11. Declare the installation as complete in the GARO Connect app and hand over the installation to the owner. If the installer created the location, it should be transferred to the real owner.

To prepare the installation (installer)

• NOTE These instructions are for the installer. To see the whole process overview of the GARO Connect app, refer to 4.14.2 GARO Connect app process overview.
• To see the overview of the symbols and buttons in the GARO Connect app, refer to 4.14.3 GARO
• Connect app symbols overview.

1. Download the GARO Connect app.
2. Log on to the GARO Connect app with provided credentials. If it is the first time logging in, edit personal settings.
3. Choose the Installers menu.
4. Select either New installation for the new location or Change installation for the existing location.
5. Change installation for existing location: Select a location.
6. Enter the installation code provided by the owner.
   • NOTE To access a location for installation, the owner of the location creates/generates a 12-letter installation code that works like a key to the location.
   • The code can be handed over to an installer by email, paper, or any other media. The installer must have the code to start an installation.
   • If a new installation code is generated by the owner, the old code becomes invalid and cannot be used. A location is normally equal to an electrical mains system of a building/site/area.
   • The installation code is only required one time per location.
7. New installation for new location: Create a new installation for a new location. During the installation, which starts with the creation of the location, the installer acts as a temporary owner. After the installation, the location is transferred to the actual owner.

To install a unit (installer)

1. Select the location to install the unit(s) in.
2. Click Add new unit.
3. Enter a device name and select Garo Entity for charging stations or Garo Entity Balance for load interface units.
   • The Garo Connect app provides the applicable installation guide based on this choice, even though the installation for each unit type is almost the same.
4. Once the unit is added, connect the unit to a group.
   • Click the unit to connect it to a group.
   • NOTE In this example, CS 1 will act as an internet gateway, therefore the group structure is set up with this unit first.
   • NOTE All units, even a single charging station, must be tied to a group. The workflow of adding units must follow the connectivity and the DLM structural paths.
   • Always start with the unit that will act as the internet gateway followed by the closest units of the different levels.
   • If more units are installed and shall work together in a DLM system, all must belong to the same communication group structure.
   • Crown icon = DLM master (Manage group load balancing)
   • Internet icon = Internet gateway/group (Internet master, communication master (manage communication groups), acting master to a mesh Wi-Fi network, “first node” in a “Wi-Fi-mesh”).
   • NOTE To make a DLM work, all units in the DLM must be part of a structured communication group. In small installations, only 1 internet gateway/communication master is required.
5. Enter a group name and set the maximum current (Ampere) for the group.
   • This is also required for a single charging station installation. If a charging station is only installed to act as an internet gateway, that is create internet access and net access, then this group size can be set to the maximum current of the charging station.
   • In such an instance, the group is never used for any direct DLM function.
   • If the first created group is to be used as an active DLM group, then it is recommended that the actual DLM current limit is entered.
6. An installation guide opens and shows the required steps to install the unit. All steps must be completed to finalize the installation.
7. Configuration.
   • a. Install the charging station(s). Refer to 4 Installation.
   • b. Scan the QR code on the bracket.
   • If the QR cannot be scanned, manually enter the ID.
   • c. Attach the charging unit and turn the power/voltage on.
8. Internet setup.
   • a. To set the internet connection settings for the first unit, the internet gateway, a direct connection must be set up between the device (mobile with the GARO Connect app) and the charging station.
   • To set up a direct connection, use the charging unit ID label to enter the credentials to the GARO Connect app. The QR code is scanned via the GARO Connect app.
   • NOTE It is also possible to enter the Wi-Fi credentials as plain text in the GARO Connect app if the QR code can not be used.
   • b. Wait until the box lights up with a solid green light. This can take up to 5 minutes.
   • c. Select how to connect to the internet:
   • ethernet cable to a router
   • local Wi-Fi connection to existing Wi-Fi with internet router
   • modem
   • as a temporary solution, a hotspot from the mobile device
   • d. The internet media icon will turn green once connected to the internet.
   • e. Close the connection between the mobile device and the charging station.
   • Once the internet is connected to the unit, the mobile device will communicate with the unit over the internet, so the direct connection shall be closed.
   • NOTE Changing internet settings will force the charging station to restart.
9. Software update.
   • Software can always be updated but never downgraded as this is not allowed due to cyber security. It is highly recommended to enable automatic update of firmware (default setting).
   • NOTE A software update over a modem can sometimes be very time-consuming. It is possible to update at a later date.
10. Settings.
    • NOTE For information on the different parameters, click the “I” icon.
11. For test charging and the ground fault protection, refer to 6.4 To do an earth fault test, Test the charging station using an EV tester or an EV, refer to To do a final functionality test of the product Finalize the installation.
12. Declare installation as completed.
    • After final testing, the installation of the charging unit can be declared ready in the GARO Connect app by clicking Completed. The charging unit becomes available to use and visible to the owner.
    • NOTE After the installation is complete each charging station can be activated and deactivated. A deactivated charging station is indicated as red.
13. Remove the ID label from the charging unit.
14. Functional test
    • The Wi-Fi credentials on this label can be used to gain unauthorized access to the charging station. For this reason, the information should be considered sensitive. Place it in a safe space location, for example on the rear side of the charging unit.
    • Perform the necessary functionality tests such as testing the load management setup to ensure the current is limited at high load conditions, refer to 4.12.15 To do a final functionality test of the product.

To install additional charging stations and load interfaces into a DLM group

• If additional units are installed into a DLM system, each unit must be defined into a group structure. The GARO Connect app tool controls the workflow order, adding one unit at a time following the closest relationships.
• The example below shows how to add the ungrouped load interface main fuse unit into the DLM home group structure. The DLM home group unit has already been created for unit CS 1.

1. To connect a unit to a group, click the unit to connect and select a suitable group structure.
   • a. Add the unit to an existing group.
   • b. Create a new superior group.
   • c. Create a new subgroup.
   • d. Create a new stand-alone group.
2. To add a unit to an existing group, select a group and click Next.
   • NOTE To add a unit to an existing group as a subgroup, name the unit, group current (maximum current), and define the superior group.
   • When a new subgroup is defined, the default proposal is to also define a new subcommunication master.
   • This is usually a good thing to do to avoid reaching the limit of 32 units in a communication group. Another reason to create a subgroup is that if a Wi-Fi mesh group is to be “started”.
3. Choose a connection type.
   • The connection type defines how the interconnection to the communication master is done.
   • By selecting an ethernet cable or Wi-Fi mesh, the connection should be quite automated, without the additional need for connection configurations later during the installation process.
   • Use the same method as when adding the first internet gateway.
   • NOTE If the interconnection uses Wi-Fi to an external IT infrastructure, then the Wi-Fi credentials must be defined later in the installation flow, using the direct connection AP to the charging station.
4. In the preview of the connection group icons indicate that the unit is set as DLM and connection group masters.
   • NOTE The group is not fully created until the ID is set.
5. Click Next to continue the installation. Complete the remaining installation steps and declare the installation finished in the GARO Connect app.
6. The unit is added to the selected group.
7. View the hierarchy of the DLM groups and Internet groups under Connection groups.
8. Continue to install the remaining settings.
   • However, the internet connection should be automatic if an ethernet cable or a mesh Wi-Fi is used. If a Wi-Fi connection is used, follow the instructions in the GARO Connect app.

Transfer location

• If the installation is performed on behalf of the owner, transfer the location back to the owner.
• To do this, click Transfer location and follow the instructions in the GARO Connect app.
• NOTE If the owner is not a user of the GARO Connect app, an invitation will be sent out via email.
