The charging station is equipped with a 6mA detection
circuit per socket. The charging current is interrupted if a DC
leakage current of 6mA or more is detected. After 5
minutes, the charging current will be switched back on. If
the 6mA DC leakage current is detected again, the station
will interrupt the charging current again.
This protocol is repeated up to 3 times while the charging
transaction remains active, after which the transaction will
be permanently terminated. If the charging cable is
reconnected, the charging station will restart this cycle.
