Description
▌General Information
The external display ED-02 is detached from the DC meter to display the meter values independent from the meter’s physical position inside the system. It is connected to the meter via a secure data line. The meter will be checked for a correct connection cyclically at any time.
The display shows billing relevant data for a charging process as well as other information.
If the meter has been parameterised for use with an ED-02, it will not be possible to start the charging process if the ED-02 is not connected.
