Carefully read these instructions and the charging instructions in your vehicle
owner’s handbook before charging your electrical vehicle.
Take special note of all information marked with the following symbols:
IMPORTANT SAFETY INSTRUCTIONS
Caution: This symbol means be careful. You are capable of
doing something that might result in damage to equipment.
Warning: This symbol means danger. You are in a situation that
could cause bodily injury. Before you work on any electrical
equipment, be aware of the hazards involved with electrical
circuitry and standard practices for preventing accidents.
Note:This means pay particular attention. Notes contain helpful suggestions
Safety Guidelines
Use this Home Box to charge electric vehicles equipped with a conductive
charge port only. See the vehicle’s owner’s handbook to determine if the
vehicle is equipped with a conductive charge port.
Make certain the Home Box’s supply cable is positioned so it will not be
stepped on, tripped over, or otherwise subjected to damage or stress.
There are no user serviceable parts inside. Refer to the Customer Support
section in this manual for service information. Do not attempt to repair or
service the Home Box yourself.
Do not operate your Home Box if it or the supply cable or housing is visibly
damaged. Switch off the MCB in the electrical cabinet and contact your
Service Representative for service immediately. Refer to the Customer
Support section in the manual for information on the Service
Representative in your area.

SAFETY INFORMATION
Warning: When using electric products, basic precautions should
always be followed, including the following:
Read all the safety warnings and instructions before using the product.
Failure to follow the warnings and the instructions may result in electric
shock, fire and / or serious injury.
This device should be supervised when used around children.
Do not put fingers into the electric vehicle connector.
Do not use this product if the flexible power cord or EV cable are frayed,
have broken insulation, or any other signs of damage.
Do not use this product if the enclosure or the EV connector are broken,
cracked, open, or show any other indication of damage
Warning:If, at any time, you think the equipment is unsafe, switch off
the MCB in your electrical cabinet and immediately contact Customer
Support for service. Do not use your Home Box until the problem is
identified and corrected.
Caution: Children should not be allowed to use this Home Box. Do not
allow children to play in or around the Home Box. Close supervision of
children is necessary when the Home Box is used.
Caution: Do not open the enclosure.
Note: This Home Box is designed according the IEC61851 Mode 3standard.
Note: This product must be grounded/protective earthed. If it should
malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. This
product is equipped with a cord having an equipment grounding
conductor and a grounding plug.
Warning: Improper connection of the equipment-grounding conductor is
able to result in a risk of electric shock. Check with a qualified electrician
or serviceman if you are in doubt as to whether the product is properly
grounded.

INSTALLATION HOME BOX
1. The installation must be done by a qualified and licenced electrician
according the local legislation.
2. The electrical installation must be free of power during the entire
installation period.
3. Since this Charging Unit uses circuits that reference to ground, no
Megging must be done after connecting to power.

6. Use 4 wood screws M4,5x35mm to mount Charging Station on the wall.
The Charging Station should be installed between 0,80m and 1,20m from
bottom to the ground.
The Charging Station does not include the
MCB or RCD. These must be installed
separately in the electrical cabinet.

The HomeBox Smart is capable of dynamically adjusting the charging
current, depending on other loads that use the same mains connection.
We call this smart mode, and it will require the following extra items:
The Sensorbox should be placed where the Mains connection enters the
building. Usually just after the kWh meter, this way it will be able to measure
the total current per phase and send this information to the HomeBox
Smart.
In order to measure the current, Current transformers are used. Clip them
around the L1, L2 and L3 wires and plug the other end into the Sensorbox.
The data cable coming from the Sensorbox should be connected to
terminals A, B, +12V and GND.
Current Transformers (type SCT 013-000) one for each phase
(usually three are required)

The HomeBox Smart has a display, which shows the charging status and
the measured current per phase. It is possible to configure all settings
using the build in menu. Three buttons below the display are used for
navigation the menu.
Hold the center button for 2 seconds to enter the menu. You can now use
the left and right buttons to go to the different menu options.
Pressing the center button, selects the option, and allows you change the
value (for example change the charging current).
What is displayed depends on the options you have set.
If you enabled smart mode (MODE->SMART) then the MAINS and MIN
option will be shown.
If you selected the CONFIG->FIXED option, a fixed cable is to be used,
and therefore the cable LOCK option is removed. Instead a CABLE
current option is shown, to let you set the max current the charging cable
can handle.
The EXIT menu option stores the settings, if you don’t want to store the
settings, wait 2 minutes (or disconnect the mains) and the setup menu
will be exited without saving any settings.

It is possible to connect up to 4 HomeBox modules to each other and let them
share one mains supply.
Software configuration
Configure the HomeBox’s load balancing option (LOADBL) and set one
module to MASTER, the others to SLAVE 1,2,3.
Make sure there is only one Master, and the Slave numbers are unique.
Example: for a two unit Load Balancing setup, set the first module to Master
and the second to Slave 1.
On the Master configure the following:
MODE Set this Smart if a Sensorbox with CT’s is used to measure
the current draw on the mains supply. It will then dynamically
change the charge current for all connected EV’s. If you are
using a dedicated mains supply for the EV’s you can leave
this set to Normal.
MAINS Set this to the capacity of the mains supply. This will be the
maximum current all EV’s combined will use.
MAX Set the maximum charging current for the EV connected to
this HomeBox.
MIN Set to the lowest allowable charging current for all connected
EV’s
On the Slave’s configure the following:
MAX Set the maximum charging current for the EV connected to
this HomeBox
After setting the Slave’s load balancing option, there will be an error message
on the display: “ERROR NO SERIAL COM”
This indicates, that the Slave unit was not able to communicate to the Master.
This message will disappear after the modules are correctly wired up.
Hardware connections
Connect the A, B and GND connections from the Master to the Slave(s). So
A connects to A, B goes to B etc…
If you are using the Sensorbox, you should also connect the A, B and GND
wires to the same screw terminals of the HomeBox. Make sure that the +12V
wire coming from the Sensorbox is connected to only one HomeBox. This
wire will provide power to the Sensorbox.
LOAD BALANCING

If an error occurs, the HomeBox will stop charging and display one of the
following messages:
ERROR NO
SERIAL COM No signal from the Sensorbox or other HomeBox
(when load balancing is used) has been
received for 10 seconds. Please check the
wiring to the Sensorbox or other HomeBox.
ERROR NO
CURRENT There is not enough current available to start
charging, or charging was interrupted because
there was not enough current available to keep
charging. The HomeBox will try again in 60
seconds.
ERROR
HIGH TEMP The temperature inside the module has reached
65o Celsius. Charging is stopped. Once the
temperature has dropped to 55o Celsius
charging is started again.
