Figure 3-2  Plug Present circuit 
The technology module assigns a current carrying capacity to the resistance value measured 
at the PP terminal (R
C
) according to the following table. 
Table 3- 4  Permitted current in the charging cable or charging connector 
Current carrying 
13 A  20 A  32 A  63 A 
Measured values for R
C 
outside of the values define here will result in an error. A charging 
operation cannot be started. 
 
Note 
If the SAE J1772 standard has been selected, the PP resistance is not evaluated!
 
Do not connect any potential PP conductor of the char
ging cable to the PP terminal! 
The maximum charging current is only limited here by the configuration of the module in TIA.  
Connector locking ACT0p/n and ACT1p/n 
The technology module enables you to use either electromotive or electromagnetic 
connector locking and to monitor it over the associated read-back input (DI) of the charging 
outlet.  
●  Locking: The connector of the charging cable is locked in the charging station after the 
vehicle has changed to STATE B (vehicle connected) and the Plug Present evaluation 
has determined a sufficient current carrying capacity of the cable. 
●  Unlocking: The locking mechanism is not unlocked until the charging cable is unplugged 
from the vehicle.
