CC613 charge controller

4.3 Connectivity

4.3.1 Master/slave connection

The charge controller serves as a data gateway. Master/slave operation requires the USB conguration

interface (micro USB 2.0, master) to be connected to the USB type A interface (slave) via a USB cable. The

master assumes the role of the OCPP backend for the slave. It connects each slave as an additional charging

point to the backend.

The master or slave role is assigned to a charge controller within the Manufacturer conguration interface.

A reboot can then be triggered and the devices can be connected via a micro USB cable (master: micro USB/

slave: USB type A). Usually, the devices connect automatically. Local access to the master/slave combination

is then only possible via the slave device. The IP address of the master must be assigned to each slave as

OCPP host name. Port 1600 must be used as an OCPP port to establish a connection with the master.

The additional IP address 192.168.125.124 is assigned to the master via the Operator tab (without assigning

a default gateway). The slave uses the IP address 192.168.125.125 to establish a connection with the master.

Master and slave conguration can be accessed via a selection page on the conguration website of the slave

(e.g. http://192.168.123.123).

4.3.2 Interfaces

USB conguration interface (CONFIG)

The USB conguration interface (CONFIG) on the front panel of the charge controller can be connected to a

conventional laptop, PC or tablet computer via a micro USB cable. This interface allows local conguration

of the charge controller. In addition, it enables software updates to be installed. The web interface can be

accessed via the IP address 192.168.123.123.

Ethernet interface (depending on the variant)

The charge controller can be connected to an existing Ethernet network via an Ethernet interface.

WiFi interface (via USB WiFi adaptor)

By using an USB WiFi adaptor, it is possible to set up a backend connection via WiFi network.

For further information on conguration descriptions and interfaces, see chapter "Conguration and testing".

4.3.3 Power contactor connection

Contactor connection

The charge controller controls the contactor, which in turn releases the current ow to the vehicle. The

contactor is controlled via a relay in the charge controller, the contacts of which are rated for 230 V/4 A (see

chapter "Wiring diagram").

Only for variants with OCPP (see ordering information)
