Installation – Electrical connection of the wallbox |
13
Proceed as follows to connect the power supply cable inside the wallbox:
1 Cut the supply cable to the required length with
the pliers.
y For wiring up group installations (see next
section), you must also cut the data cables to
the required length.
2 Insert the individual conductors of the power
supply cable into the respective terminals of the
RCCB and tighten them using the screwdriver
(torque: 2.5 to 3 Nm).
y End ferrules must be fitted on flexible
conductors.
y Operate the spring-loaded mechanism of the
PE terminal and attach the protective earth
conductor.
y Use the connection patterns listed below to
allocate the individual conductors.
Connection pattern for 3-phase TN system
Designation Conductor color Marks for
Phase 1 current-carrying conductor Brown
5 – L1
Phase 2 current-carrying conductor Black
3 – L2
Phase 3 current-carrying conductor Gray
1 – L3
Neutral Blue N
Protective earth Green-Yellow PE
Connection pattern for 1-phase TN system
Designation Conductor color Marks for
Phase 1 current-carrying conductor Brown
5 – L1
Neutral Blue N
Protective earth Green-Yellow PE
Please note that the colour-coding convention used above is not internationally standardised.
Please ensure that the conductors that are pre-fixed to the RCCB terminals remain attached correctly
after connecting the power supply cable.
If desired, the 3-phase Wallbox eMH2 model variant can also be connected and operated on a single
phase at terminal 5 – L1: However, in this case the rated output for the wallbox will not be achieved.
The electronic components of your wallbox will be damaged if a voltage above 250V is applied between
the 5 – L1 current-carrying conductor and the neutral conductor!
