3. CLU® - Cloud Link Unit general description
The CLU is a DEFA control unit used to optimize charging of electric vehicles in locations
with limited power supply. The load management ensures that the available electrical
capacity is distributed evenly between up to 16 charge points, preventing a situation
where the rst user to connect also receives the most power. The system will never
consume more power than assigned. The CLU will, therefore, help to avoid peaks in power
consumption and thus associated costs.
The CLU can be used together with a single charge point as well as in larger charging
facilities. It has two primary functions:
• Distribute available power evenly between the charge points in use.
• Operate as the link between the charging facility and the internet (CloudCharge).
The unit can be retrotted into existing facilities and more charging stations can be
connected if required.
If internet access through LAN cable or GPRS/SIM is available, the CLU allows for the use of
CloudCharge®management system. Subscription fee for CloudCharge is not included in CLU.
Power distribution between the charging stations do not require internet access. A CLU
without online access can still do power sharing, but not access control.
Every CLU is congured by each country’s DEFA service department and tailored to t the
individual needs of each facility.
CLU is only compatible with charging stations from DEFA.
DISTRIBUTION OF POWER
In facilities with more than one charge point, the available power will be shared between
the charge points in use. When a vehicle is fully charged, or is disconnected, the available
power will be evenly distributed among the remaining vehicles still charging.
The CLU can control up to 16 charge points on a cabled RS485 bus connection. A 5V DC
low voltage power supply (LVPS) is included in the box. DEFA recommends the use of a
separate fuse for the CLU (for example a B-6A fuse (MCB) or equivalent RCBO).
1. Safety information
This installation manual describes the necessary steps to install a CLU. It contains
important instructions and warnings that must be followed. CLU must only be installed by
a licensed electrician in accordance with national and local regulations. For other products,
see the separate installation manuals included in each product. Good installation practice
must be followed.
A warning symbol indicates that extra care must be taken. If not followed, damage and/or
injury can occur. Read all warnings before installing this product.
The CLU is to be used exclusively for its intended purpose.
DEFA cannot be held liable for any damage or inadequate outcome caused by incorrect
conguration or use.

QUEUES
In a charging facility where more vehicles are connected than there is power available, a
situation arises where cars are queued pending available capacity. Some vehicles will not
wake up when taken out of the queue. All charging facilities should, therefore, be scaled to
ensure that all vehicles at any time receive at least 6A to prevent them from going dormant.
5. Product description
6. Before installation
To be assessed before installation:
• Distribution network: TN, IT or TT network
• Available power for EV charging without xed building loads (lighting, heating etc.)
• Single-phase or three-phase charging
• Number of charge points
• Number of CLUs
• Available charging current for each charge point
• Plan for a connection pattern
• Fill in the facility form underneath "My facility" in the installer portal at www.defa.com/facilityform/
4. System requirements/limitations
CLU is intended for charging equipment, supplied by:
• 230V AC and 400V AC TN-S, star topology three phase balanced system, hereafter
called TN network.
• 230V AC IT delta topology, with 120 degrees between each phase (Norway only),
hereafter called IT network.
One CLU should be provided per power source. That is, one subdivision with two secured
branches equals two CLUs. However, there are two exceptions:
1. All charge points can be connected to vehicles in any order without exceeding the
limit of the main fuse. For example: Several charge points, two branches (fuses that
supply the facility) and one CLU set to 63A, both branches must then each be sized
for a charging current of 63A.
2. When power sharing is not required, and CLU is only used as a link between the charge
point(s) and CloudCharge.

7. Margin of safety
MARGIN OF SAFETY FOR SITE MAIN FUSE
The power sharing system makes it possible to deviate from a strict principle in the
regulations, with concurrence factor of 1. Make sure the facility in planning and in practice
never exceeds its limitations.
For installations with power-sharing systems, DEFA recommends the use of conservative
safety margins. All values should be rounded down and have at least 5% margin of safety
on site and fuse size of the charging point.
Please note that the margin of safety must be calculated based on the fuse size without
the xed building loads (lighting, heating etc.) deducted.
NB! The signalling between the vehicle and the charging infrastructure will normally never be
more precise than ± 5%. DEFA therefore recommends a minimum of 5% margin of safety.
NUMBER OF CHARGE POINTS
The standardization for charging electric vehicles limits the number of vehicles that can
charge simultaneously. Because of this, every vehicle should at all times have at least 6A
available.
A facility is normally dened as overnight charging in shared car parks, such as home
cooperatives. The management principle requires a power allocation for charging with an
overload protection that does not supply other xed loads.

Allowing the system to create queues is an option if there are more charge points installed
than recommended in a facility with limited capacity. Queuing is supported by the CLU, but
since certain types of vehicles do not wake from hibernation when taken out of the queue,
the maximum number of charging vehicles should never exceed what is advised in the
tables below.

8. Phase connection pattern
DEFA recommends phase rotation in the distributed circuits, one step per charge point,
as shown in the example installation diagrams. By using a connection pattern with phase
rotation, the system ensures an even load distribution among the phases.
Phase rotation is important for single-phase charging, and for three-phase charging when
single-phase vehicles are connected. PE-wiring is intentionally not shown in the installation
diagrams.

9. Communication wiring
NETWORK TOPOLOGY
A daisy chain topology is easily implemented by using the connector inside each wallbox to
link the upstream and downstream charge points to the network. Select a colour code for
each terminal (A, B and M) and use the same colours throughout the network to minimize
the risk of incorrect wiring. All wallboxes have 12 terminals for connecting the bus, 6 for the
bus in and 6 for the bus out. The connector pinout is shown in the next chapter.
There are advantages by using a daisy chain topology (gure to the right) instead of a star
network (gure to the left):
• The bus is considerably shorter
• Fewer components
• Easier troubleshooting
• No extra hardware
• Fewer connection points

CHARGING
1. All charge points must be connected the
same way:
Brown = L1, Black = L2, Grey = L3, Blue = N
2. Create a xed phase rotation at the
output of the fuses, or terminal blocks,
one rotation-step per connected charge
point.
3. All phases may be distributed with a
regular "L1-L2-L3-N" bus bar suitable for
4-pole DIN block devices.
NB! All wallboxes must be connected to the same grounding point; otherwise the
communication may be lost, or CLU may be damaged.
!
When installing the wallbox, assess and select a connection pattern and phase
distribution. Then connect the power cables to the wallbox according to the chosen phase
connection pattern.

CONNECTING THE WALLBOXES TO THE CLU
Connect a communication cable between the CLU and the wallboxes. Use a communication
cable with at least two twisted pairs of a single bus system, and four twisted pairs for a
double bus system. The gures below show where a CAT5/CAT6 cable with solid copper
core wires may be connected to the wallbox.
WIRING
The bus requires at least 3 conductors: 2 signal wires (A and B) and 1 signal ground
reference (M). If a twisted pair cable with multiple pairs is used, one pair must be used for
A and B and one pair for M.
GROUNDING AND SHIELDED CABLES
A ground wire is required so that all nodes on the bus share a common ground reference.
The ground wire could be a separate wire or a pair of the twisted pair cable. If a shielded
twisted pair cable is used, the shield must be connected to ground at one end only as
shown in the gure below.

9.7 COMBINING 1ST AND 2ND GENERATION WALLBOXES IN THE SAME NETWORK
For retrotting of rst-generation wallboxes in a new facility, or new wallboxes in an existing
facility with rst generation wallboxes, the bus connection will become a combination of
RJ12 connectors and push insert clamps. Pin 3 and 4 from the RJ12 connector must be a
twisted pair as shown in the gure below.
eRange Generation 1/Salto
RJ12 16
1 6
The above gures show the location of the connector for bus communication in the single
wallbox. For double wallboxes, see chapter 9 ”Communication wiring”.

defa.com26 English 27Englishdefa.com
10. Charging station with two charge points
For three-phase IT network with single-phase charging, on a 3-pole fuse, be aware of the
total current in the common phase.
The gures below are examples. This also applies for other fuse sizes and charge
currents.
11. Conguring the charging station for CLU
Each device in the network must have a device address to identify the different controllers.
The address must be set on each controller at the time of installation. When connecting
an RFID reader to a wallbox, the RFID reader uses the same bus as the controller. No
separate wiring is therefore needed from CLU to the RFID reader.
• Open the charging station and connect the "USB-RS485 interface" (DEFA adjustment kit)
to the RJ12 connector.
NB! The adjustment kit is required to congure the devices in the network.

With DEFA Charge Point Congurator (DEFA CPC), set the maximum charging current.
(See separate manual for DEFA CPC)
• Set the unique address to each charge controller according to the chosen connection pattern.
Note: DEFA recommends that for single-phase charging with phase rotation, the following charge controllers is
connected to the same phase(s):
• Address 1, 4, 7, 10, 13 and 16
• Address 2, 5, 8, 11 and 14
• Address 3, 6, 9, 12 and 15
This connection and address pattern must be followed to ensure an even distribution of charge points among
the phases, even when there are fewer than sixteen charge points installed.
The CLU system can be updated by for example adding chargingpoints via the installer portal.
Address the charge points with ascending numbers to ensure easy expansion and a symmetrical number of
charge points per phase, as shown above. The number of charge points already installed + 1 is then the next
available address.

12. Labeling
Mark each chargingpoint/connector with the correct label (labels is included in the CLU package). The label
is set based on which CLU the chargingpoint is connected to and which adress the chargningpoint has.
Labeling is required the facility is connected to a backend system.
Example: A table with address and labeling of the chargingpoint

CLU COM
To install the CLU COM, rst complete the steps described in previous section “CLU Basic”.
• Mount the modem (3.5 modules) on to a DIN rail.
• Mount the 12V DC power supply (1 module) on to a DIN rail.
• Install the antenna in an appropriate place.
NB! The antenna requires reception of sufcient quality to function as intended. Check the
reception at the location before installing the CLU COM. The CLU operates with GPRS/2G-4G.
• Connect the cable between the modem (RJ12) and the 12V DC LVPS.
• Connect the USB - Mini USB cable between the CLU and the modem.
• Connect the antenna to the modem.
To complete the installation, go to section “CLU Basic and CLU COM”
CLU BASIC AND CLU COM
• Route the communication cables away from line-voltage elements. Do not route the CLU
cables in parallel with supply lines.
• Congure the charging station and connect the USB interface(s) to any of the USB ports
on the CLU.
NB! Do not connect/disconnect a USB interface from a powered CLU. This may lead to damage
of equipment.
• Power the CLU by connecting the 5V DC LVPS to 230V AC.
Warning! Check connections before powering!
If connected correctly, both red and green LED status indicator on the USB interface
connected to the CLU will ash rapidly after approximately 120 seconds. If none or only one
of the LED indicators are ashing, see the chapter for troubleshooting.

14. Online CLU
INSTALLING CLU IN A LOCAL AREA NETWORK (LAN)
The protocol between CLU and the charge points is proprietary. The charging stations are
therefore not assigned IP addresses. Only the CLU has an IP address in the data network.
The CLU requires a data network with DHCP, but reservation of an IP address in the network
can be used. The CLU normally has an OUI with the rst six characters being B827EB. All
data is initiated by the CLU via WebSocket on port 443, but data will both be sent to and
received from the CLU. The IP address of the server will vary.
NB! Please note that some networks may need an exception in the rewall to let the CLU
communicate to the backend as intended.
INTERNET FOR MORE THAN ONE CLU IN A FACILITY
Several CLU can be connected to the same internet connection. Either through a common
modem or a common ethernet switch. Keep in mind the loss of redundancy when using
one common network device. The two main network solutions are shown in the illustrations
below.
15. Download of conguration
NB! CLU device must be connected to network to download the conguration. (For more info
related to network connection, see chapter 14).
NB! The Facilityform for the facility need to lled in and veried before the conguration will be
available for download. Link: https://www.defa.com/facilityform/

2.
To download the conguration, click on the actual CLU
("Click to download"), then you will be asked to scan the
QR-code on the CLU device or type the serial number
manually.(step 3)
3.
Scan QR-code on the CLU device. If you are not able to
scan the QR-code, click on "ll in manually".
You will recive and email from the one who created the facility in the facility portal. If
you haven't recived the email or ordered the facility configuration, go to the following
link www.defa.com/facilityform/
1a.
Use your smartphone or tablet and click the link received in
the email. (NB! the one who created and lled in the facility
information will receive the email, so make sure to have
access to this email.)
1b.
Alternatively scan the QR-code on the CLU device to be
guided in to the installer portal. Be aware that, the one who
lled in the facility data normally has access to the facility in
the facility form.

4.
Scan one of the chargingpoints connected to the CLU.
Click on the "Scan" button
5.
You will now be guided to the CLU overview with updated status
for the CLU device and conguration.
16. CLU functionalities
MAXIMUM PHASE CURRENT DELTA
The CLU is assigned a maximum allowed delta current between the phases with the highest
and lowest load, respectively. The maximum phase current delta is considered in relation
to the size of the main inlet fuse size of the building. A charging facility with a maximum
charging current of 32A in a building with a main distribution board of 3000A is not likely
to have much impact on the delta current of the building and can thus be allowed to have a
higher maximum phase current delta than a building with a 250A main inlet.
DEFA recommends that the maximum phase delta current never exceeds 30% of the main
inlet fuse size. That is, for example, 45A for a 150A fuse.
PLUG & CHARGE
When «Plug & Charge» is enabled, RFID readers will be ignored and the CLU will accept every
transaction without authentication of users. In this mode no payment solution is provided.
FREE DURING LOST SERVER CONNECTION
When enabled, and the internet connection is broken, the CLU will be set to «Plug & Charge»
if it has not received any data from the server in 5 minutes. Vehicles connected during
the 5 minutes before timeout, must have a plug cycle to start charging. If this mode is not
enabled, charging will not be possible when the internet connection is missing.
PRIORITY FOR USERS WITH SPECIAL REQUIREMENTS FOR POWER
In housing cooperatives or businesses some users might need a fully charged vehicle every
day. By using the priority function the vehicle will, when charging on a prioritized charge point,
receive the charge points maximum charging current if available. All prioritized charge points
will have the same priority while all other charge points will share the remaining capacity.
NB! A prioritized charge point must be specied as a xed load when calculating distributed
power per charge point in a charging facility.
