CP vehicle (simulation)
The CP rotary selector switch can be used to simulate the vehicle side. The vehicle side is
simulated by means of resistors between CP and the protective conductor. All specifications can
be taken from the following table.

CP signal output (+ protective earth)
The CP output terminal is connected to CP and the protective earth of the charging station. The
green terminal is directly connected to the protective earth. These terminals can be connected to
an oscilloscope to check the output signal. Pulse width modulation (PWM) is expected. The signal
should be designed according to IEC/EN 62851-1 and IEC/HD 60364-7-722.
8.5
CP error test key "E" (simulation)
The CP error test key simulates an error according to IEC/EN 6185-1. When this key is pressed,
the CP signal is applied to the PE conductor via a diode. As a result, the charging process should
be aborted.
8.6
PE error test key (simulation)
This key can be used to simulate a PE error. When pressing the key, the charging process should
therefore be aborted.
8.7
Signal lamp for phase connection
The signal lamps indicate that voltage is present at the corresponding phase.
Note:
If the neutral conductor is not connected, the signal lamp will not light up. The signal lamps
do not signal the connected phase rotation direction.
8.8
Schuko plug connection
L1, N and PE in the charging station are tapped by the Schuko plug connection. This connection
can be used to make power measurements, for example to check a current display.
Note:
This connection is protected by the built-in 10 A fuse.
