What is the biggest problem when installing many chargers?
• Available power is limited (upgrade of installation is very expensive).
How do we solve the problem?
• Most eicient distribution of the available power – without extra cost / additional device.
Which factors did we take into account?
• A car stays longer than it charges – Wallbox will use that available power.
• Each installation has their own characteristics – Wallbox allows a most flexible installation.
• The installation is often not connected to the Internet – Wallbox does not require Internet-connection.
• When connecting many devices, easy troubleshooting is key – Wallbox gives full visibility over the status.
INSTALLATION GUIDE
Eiciency
Re-assignation of unused power, example:
• A car uses actually less than it has assigned from power sharing.
• A car is full and will not charge anymore.

• If a charger looses connection (due to bad cabling) it can charge with 6 A and Master will say “missing slaves”
• A newly powered on charger will be added to the system within 1 minute.
Flexibility
INSTALLATION GUIDE
• Connect between 1 and 24 chargers with the Master.
• Any kind of installation .
• Configuration of the system (power/chargers) can be easily changed.
• Up to 250 m distance of communication.
Possibility to install more chargers than can charge at the same time

2.1 Positioning in the System (T/NT-Chargers)
T NT NT NT T
When installing the Wallbox in Power Sharing, the location is important to take into account.
The Power Sharing system includes two Terminating (T) chargers and the rest of Non­Terminating (NT) chargers as shown in the image.
Each charger includes an electric element (resistor) that defines wether it is T or NT:
• Copper: The way to turn it from NT to T is to change the switch position it has inside.
• Commander or Pulsar: There’s an specific order for connecting Commander or Pulsar,
which is pointed in the proper charger as NT or T.
Once the location is clear, the charging station can be installed according to its delivered installation manual.

2.2 CAN Cabling (CAN-H/-L)
• The chargers communicate through a cabling system that connects the chargers to the ones next to it.
• The cabling consists of a CAN-low (CAN-L) and a CAN-high (CAN-H).
• We recommend to use the following cable-type: Ethernet Class 5E no shield, 1 pair.
• A total maximum length of 250 m can be installed.
2.2.1 Instalation: Cabling (Copper)
T TNT
INSTALLATION GUIDE
Copper has two slots for input and output cabling so the conjunction is done inside the char­ger.
Copper NT connectionCopper T connection
• CAN-H must be connected to CAN-H
• CAN-L must be connected to CAN-L

INSTALLATION GUIDE
2.4. Instalation: Cabling (Commander/ Pulsar)
Commander and Pulsar only have one slot so the conjunction is done with external terminals.

• CAN-H must be connected to CAN-H
• CAN-L must be connected to CAN-L

INSTALLATION GUIDE
3.2 Master Configuration
Once the system has been powered on, the charger will visualise the state “unconfigured master” by a red LED or the dashboard of the charger.
Commander
If you move further to the settings of the Master, the power sharing system can be configured:
Commander
* If the Master is a Copper, you need to have a myWallbox account and connect via Bluetooth and the App with the charger (see Copper User Guide). Once connected, select the settings->power sharing to configure the system.
In the Master 3 parameters need to be configured:
• Number of Chargers in the Power Sharing System (to assure that the master knows all chargers connected).
• This number must include the master charging station
Pulsar / Copper
Pulsar / Copper
• Maximum Current per Phase
• This value determines the maximum that your installation can carry. Typically this value can be drawn from the main MCB, that has been installed for this power supply.
• Minimum Current per Charger (6 A or 10 A)
• While the standards define a minimum current of 6 A (default value), some cars need to have a minimum current of 10 A.

4.1 Status Visualisation
In queue by power sharing: Not enough power available for this charger.
• If the power has already been reduced to the mínimum, the newly plugged cars will go into this state
• Once the system has enough power available (e.g. a car is full) it will start charging

5. TROUBLE SHOOTING

Power Sharing Smart

5.1 Troubleshooting
Upgrading from older Power Sharing Versions
As Power Sharing is a functionality that is working across our charging stations, and not only on a single one, all chargers must work the same. Therefore, when upgrading from an older version of Power Sharing, you need to update the Sof­tware of all of them. Our user guides explain you the update process. Once the update of all chargers of the system has been performed, follow the chapter 4 of this manual. After, you are good to go.
Please take into account that the setup of the system (Chapter 1 and 2 of this manual) is kept identical
INSTALLATION GUIDE
Charger(s) have a red LED/HALO/top screen
• After the start up, this is the default colour on a power sharing net. If it lasts more than around 30 seconds, then check that the net is configured properly. If not, set the net and wait from 5 to 30 seconds.
• Make sure that the nº of chargers includes the master.
• Make sure that the maximum current per phase is set properly and that is higher than the minimum to be assigned.
Charger(s) have a blinking green LED/HALO or on Commander appears the message “Slave not paired with the power sharing network on the Power Sharing menu”.
• Poor contact on the CAN cables. Check that all the CAN cables are properly connected on the chargers.
• Wrong resistor value between CAN lines. Power o all the charger and measure the Ohm resistor between CAN-H and CAN-L, it mut be around 60 Ohms.
Resistor’s value between CAN lines is dierent than 60 Ohms
• If it is higher is because there’s only one charger with the terminal resistors. If it is lowe is beacuse there are more than 2 charger with terminal resistors.
• Make sure that the two ends of the line have the “T” switch (if there’s the switch) selected or that the resistors are on the correspondant chargers.

5. Troubleshooting
Erratic Behaviour
• Poor contact on the CAN cables. Check that all the CAN cables are properly connected on the chargers.
• Wrong configuration on the master.
• Wrong resistor value between CAN lines. Power o all the charger and measure the Ohm resistor between CAN-H and CAN-L, it mut be around 60 Ohms.
Charger keeps waiting for current eventhough there’s no other car
• The current assignation may last up to 30 seconds.
• Make sure that there are no schedules programmed.
