| Installation – Commissioning the wallbox

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
(230V).
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.
3 Place the upper part of the housing onto the
housing base.
4 Fix the upper part of the housing to the housing
base using the screws removed in Step 9.
5 Switch on the RCCB in the wallbox and/or the
domestic power distribution.
6 Now lock the housing cover using the key.
The installation of the Wallbox eMH1 is now complete and the wallbox switches to normal operating mode.
