Connect the twisted wire strands of the entering
data cable with the left hand spring terminal of
the first Slave wallbox.

Connect the twisted wire strands of the exiting
data cable with the right hand spring terminal
in the Slave wallbox and route the cable to the
next Slave wallbox (if used).

For correct functioning of the group installa-
tion, the end of the data wiring chain must be
terminated using two terminating resistors
(120 Ohm).

Commissioning the wallbox
To commission the wallbox, the power supply cable must be connected to the electricity grid.
The following working steps must be carried out with the utmost care: There is a risk of electric shock if
conductive components are touched.
1
Switch on the MCB in the domestic power distri-
bution box.
y
As soon as the wallbox is connected to the
electricity grid, the green LED will begin to
pulsate, the other LEDs will remain OFF.
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.
y
In single phase installations, the voltage is
measured 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).
