NOTE
Authentication of the Wallbox eM4 Twin
Depending on the model version, the Wallbox eM4 Twin can be configured differently during
installation.
x Controller: A Controller can be operated as a stand-alone wallbox or with a backend.
x Controller with Extender: A Controller can be operated with one or more Extender wall-
boxes as a group in a backend or without a backend.
x Stand-alone Extender: An Extender configured for stand-alone operation is operated
without a backend.
If it is necessary to authenticate the charging operation via an RFID card, carry out the
following steps 5 to 7. If authentication is not required, go to step 8.
5 Check the status indicator of the wallbox
(display: 1 cycle).
x If the charging operation has to be
enabled using an RFID card, a blue
chase light is shown dynamically on
the status indicator.
x Anti-clockwise: right charge point
x Clockwise: left charge point
6 Hold a valid RFID card in front of the
status indicator.
7 Check the status indicator and acoustic
signals of the wallbox.
x If the RFID card has been read
successfully, the wallbox emits a short
sound signal and the wallbox checks
the authentication of the RFID card.
