The CPX communication box controls the charging process
fully automatically and performs the following functions:
 Detecting the current-carrying capacity of the charging
cable with resistance coding. Unsuitable charging cables
are rejected.
 Verification of the conditions for proper charging
 Communicating with the vehicle using the CP contact.
The charging current upper limit is communicated to the
vehicle with a PWM signal. The protective earth
connection to the vehicle is checked at the same time.
 Controlling the locking of the charging plug in the
charging socket (for devices with charging socket Type
2).
 Controlling the charging contactor.
