CC613-Hxx charge controller
4.3.8 PE monitoring
The PE monitoring checks whether there is a connection from the CC613 to PE. For this purpose, L1 must be
connected to WA. The cable length is limited by its capacitance per unit length.

test: WA is coupled to PE via a protective circuit and with approximately 140 kΩ.
Above 500 V, a
leakage current flows to PE. Test voltages above AC 1000 V/1 sec. are not permissible!
4.3.9 Control Pilot (CP) and Proximity Pilot connections (PP)
The Control Pilot (CP) and Proximity Pilot (PP) contacts connect the charge controller to the socket-outlet, en-
abling it to communicate with the vehicle and the cable plug. The PP contact detects the presence of the plug
and the CP contact exchanges control signals between the electric vehicle and the charging station (see IEC
61851).
i
PP is not required if the charging cable is permanently attached.
4.3.10 Emergency opener
The emergency opener is integrated as a circuit group in the charge controller. In the event of a power failure,
the plug of the charging cable is automatically unlocked so that it can be removed
4.3.11 Residual direct current monitoring module (RDC-M)
For residual current detection in an AC charging system, an integrated residual direct current monitoring
module (RDC-M) is used. This module uses an external magnetically shielded measuring current transformer.
This allows the use of a residual current device (RCD) type A instead of an RCD type B. The relay in the charge
controller is de-energised if, during the charging process, a fault current

4.3.12 Connectivity with Modbus meters (depending on the variant)
The use of a meter is not mandatory. It is necessary if measured values are required during normal operation.
The meter is connected to the Modbus meter interface (terminal B) of the charge controller. Various Modbus
meters are currently supported, including:
• ABB B23 series
• B-Control EM300-LR/EM300-LR (TCP)
• Carlo Gavazzi EM200/EM340
• Eastron SDM120/SDM220/ SDM630 series
• Finder
• Garo EM270/GNM1D/GNM3D/GNM3T/GM3T
• IME CE4DMID31
