CC613 charge controller
4.3.1 Master/slave connection
The charge controller serves as a data gateway. Master/slave operation requires the USB configuration inter-
face (micro USB 2.0, master) to be connected to the USB type A interface (slave) via a USB cable. The master
becomes the OCPP backend for the slave. It connects each slave as an additional charging point to the back-
end.
The master or slave role is assigned to a charge controller within the
Manufacturer
configuration 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 OCPP port for establishing the connection with the master. Ethernet or
WLAN can be used for the connection between master and slave.
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 configuration can be accessed via a selection page on the configuration website of the slave
(e.g. http://192.168.123.123).
4.3.2 USB configuration interface (CONFIG)
The USB configuration interface (CONFIG) on the front panel of the charge controller is connected to a con-
ventional laptop, PC or tablet computer via a micro USB cable. This interface allows local configuration of the
charge controller. In addition, it enables the installation of software updates (for a configuration description,
refer to chapter "Configuration and testing"). The web interface can be accessed via the IP address
192.168.123.123.
4.3.3 Ethernet interface
The charge controller can be connected to an existing Ethernet network via an Ethernet interface. For further
information, refer to chapter "Configuration and testing".
4.3.4 STATUS LED
The "STATUS" LED on the front panel indicates the following system states:
Power on/system not ready for operation
System is starting
System started, not ready for operation yet
System ready for operation
System error
4.3.5 12 V power supply
The charge controller is supplied with power from a 12 V main voltage source at the +12V and 0V connec-
tions.
4.3.6 Contactor connection
The charge controller controls the contactor, which in turn controls the power flow toward the vehicle. The
contactor is controlled via a relay in the charge controller, the contacts of which are rated for 230 V/4 A.
