9.2 Emergency release of charging plug

If the unlocking function fails, the charging plug may be
mechanically locked in place in the socket panel by an
actuator.
The charging plug cannot be removed and must be
unlocked manually.

9.3 System monitoring

Fig. 22: System monitoring
The system monitor checks the three phases (L1, L2, L3)
and the neutral conductor (N) of the charging station's
power supply for correct phase sequence, phase failure or
undervoltage.
In single-phase charging stations (3.7 / 7.4 kW), the
system checks only for mains failure and undervoltage.
The operating status is indicated by three LEDs:
No. Description
A
All LEDs light up. All three phases are present,
clockwise rotating field is applied.
B
Phase failure / power failure (only for three-
phase units)
The corresponding LED is off.
C
Anti-clockwise rotating field (only for three-
phase units).
A flashing LED moves from L3 ... L1.
D
Undervoltage between two phases or between
phase and neutral conductor.
L - L = < 295 V
L - N = < 170 V
The corresponding LED flashes.
