Maintenance
Except for testing the integrated RCCB, the eM4 Single Wallbox is basically maintenance-free. However, we still
recommend the wallbox is cleaned and the charging socket checked regularly.
Use only a dry cloth for cleaning the wallbox. Do not use aggressive cleaning agents, waxes or solvents (such as
x
cleaning fluid or paint thinner) as they may dull the status indicator and surface of the wallbox.
The wallbox must under no circumstances be cleaned with a pressure cleaner or similar device.
x
Check the housing and the charging socket of the wallbox regularly for any damage.

Reading the energy meter
The energy meter on the side of the Wallbox eM4 Single shows various information about the charging operation via
three display lines. In contrast to the top line, the values displayed in lines 2 and 3 are switched cyclically:
Total electric energy consumed
A
The top line always shows the total electric power
consumed in kWh, and therefore the sum of all the
electrical charge obtained via this particular charge
point. This line is not switched.
Current or last electric energy consumed
B
In this state, the second line shows the electric
energy in kWh during the active (
(
) charging process.
C
Charge point allocation
After switching, the second line on the left-hand side
shows the identification that was assigned to the
charge point during installation.
Malfunction display
D
In this state, the third line shows the code for identi-
fying a malfunction (error, note, warning).
Duration of the charging operation
E
After switching, the second line in this state shows
the duration of the active charging operation in
hours, minutes and seconds.
Current electric power consumption
F
In this state, the third line shows the active power
that is currently being drawn by the vehicle: During
charging, the value varies dynamically; without a
vehicle connected, the value is 0.0 kW.
