Only qualified electricians may assemble and install the SMART CONNECT KNX e-charge II.
Specialist knowledge of KNX is a prerequisite.
Anyone may configure the SMART CONNECT KNX e-charge II. We recommend that configu-
ration is done by a system integrator with sound specialist knowledge of KNX and using the
ETS.

2 About SMART CONNECT KNX e-charge II
2.1 Proper use
Via the SMART CONNECT KNX e-charge II, up to five compatible charging points can be integrated into
the KNX system.
The SMART CONNECT KNX e-charge II is a KNX system device and complies with the KNX guidelines.
Installation: compatible charging points
The SMART CONNECT KNX e-charge II supports a wide range of models from many renowned manu-
facturers. Please see our product page for a list of compatible models.
Configuration: compatible ETS version
Simple integration into the KNX system (completely programmable via ETS):
• ETS from v5.7.4.
• Product database entry: Download the product database entry from our website www.ise.de or from
the ETS online catalogue free of charge.
KNX Secure
• The required KNX Secure certificate or the FDSK (Factory Default Setup Key) that it contains can be
found on a sticker on the side of the device and is also enclosed with the device.
• For maximum security, we recommend removing the sticker from the device.
• Keep the certificate in a safe place.
• You cannot restore the certificate yourself.
• Please contact our support team if you lose the certificate despite utmost care.
Important
ise Individuelle Software und Elektronik GmbH assumes no liability for damage caused by
improper use or use for purposes other than or contrary to the intended purpose.
The SMART CONNECT KNX e-charge II is KNX Secure.
The device is compatible with KNX Secure. KNX Secure offers protection against
manipulation in building automation and can be configured in the ETS project.

2.2 System
The SMART CONNECT KNX e-charge II is connected to the KNX installation via KNX/TP. Depending on
the model used, charging points are connected to the gateway either via IP or RS485 (Modbus). The
SMART CONNECT KNX e-charge II unites the required connections in one gateway. Thanks to the inte-
grated RS485 connection, no additional USB adapter is required.
Within the KNX installation, depending on the configuration, status information can be called up via a
visualisation, for example, or actions can be triggered via a push button.
Figure 1: System at home
2.3 Functions
Integration of charging points
The gateway enables the integration of compatible charging points in your KNX system. Configuration
is carried out entirely in the ETS. You do not require any additional software and have all data in one sys-
tem.
Grid-supporting control
The SMART CONNECT KNX e-charge II enables the grid operator to control the power consumption if
necessary by reducing the charging current or interrupting the charging process. Control or interruption
of vehicle charging may occur during high load periods in order to prevent a critical grid situation.
The installation and commissioning of charging stations may be subject to notifi-
cation or approval from the grid operator. Therefore, please observe national regu-
lations as well as the local regulations of the grid operator.
In Germany, a notification obligation exists pursuant to Section 19 of the Low Volt-
age Connection Ordinance (NAV).

Dynamic load management
The dynamic load management, or DLM for short, controls the current distribution without overloading
the mains connection. The DLM coordinates the available charging current depending on the general
charging current in the building. If consumption in the building decreases, more electricity is available
for charging the electric vehicles at the charging points. This way, the DLM ensures the effective utilisa-
tion of power from the available mains connection. Despite various high power-consuming devices in
the building, one or more electric vehicles can be charged at the same time. The DLM also offers the
option of prioritising a charging point.
The two main factors for the use of the DLM are the use of an intelligent measuring system, e.g. a smart
meter, and overcurrent protection device dimensioning.
Figure 2: System in commercial buildings
Depending on the on-site conditions, a smart meter is recommended as the intelligent measuring sys-
tem. If the installation already exists, an intelligent measuring system is implemented as follows:
• If an electromechanical meter is installed, a smart meter must also be connected.
• If an electronic household meter is installed, an interface with an optical head is used to read out and
send the values to the KNX bus.
Smart meter and optical head interface requirements
• Communication at adjustable intervals
• Transmission of actual values (consumption values) measured in current or power
• KNX capable

This documentation uses the term “smart meter” to refer to all types of intelligent measurement sys-
tems.
The DLM is an optional function that can be used depending on the use case.
► See Activating dynamic load management, page 39.
► See Disabling dynamic load management, page 41.
Prioritisation of one charging point
Through the use of dynamic load management, you can prioritise one charging point. The electric vehi-
cle at this charging point will be preferentially supplied with the largest possible charging current.
Charging points can only be prioritised via the ETS.
► See Activating dynamic load management, page 39.
Mixed operation
Up to five charging points from different manufacturers can be integrated in mixed operation. Mixed op-
eration implies that you can install charging points with IP connection and RS485 connection (Modbus)
together on one gateway.
Diverse statuses and actions
The SMART CONNECT KNX e-charge II offers various other functions, the implementation of which de-
pends on the charging point model. See the overview on the product page for the full range of functions.
More information on the individual functions
► See Group objects, page 43.
The SMART CONNECT KNX e-charge II does not imply the function of a smart
meter gateway.
IP connection
When integrating charging points with one IP connection, various models can be
combined.
RS485 connection (Modbus)
When integrating charging points with an RS485 connection, only one model type
can be used on the RS485 connection. In order to avoid communication problems,
the following is also recommended: Do not install any additional devices on the
RS485 bus line apart from the charging points that are to communicate with the
SMART CONNECT KNX e-charge II.
