Commissioning the wallbox
To commission the wallbox, the power supply cable must be connected to the electricity grid.
DANGER!
Dangerous electrical currents
The following working steps must be carried out with the utmost care: There is a risk of electric shock if conduc-
tive components are touched.
1 Switch on the MCB in the domestic power distribu-
tion box.
y As soon as the wallbox is connected to the elec-
tricity grid, the green LED will begin to pulsate, the
other LEDs will remain OFF.

WARNING!
Checking the RCCB and MCB
Should the LED not pulsate, check the RCCB and the MCB inside the Wallbox eMH2 and switch the pivot levers
to position I if necessary.
2 Measure the voltage at the RCCB terminals using the
voltage tester.
y In single phase installations, the voltage is meas-
ured between the phase and neutral conductors.
y In 3-phase systems, all phases are measured
against each other (400 V) and all phases are
measured against the neutral conductor (230 V).
WARNING!
Conducting all necessary checks
Now conduct all locally required checks and testing of the wallbox and its electrical installation. These include
the following tests:
Effectiveness of protective earth conductor connections
Insulation resistance
Loop impedance
Voltage drop
RCCB tripping current and tripping time
Rotating field testing
as well as additional tests according to local regulations.
