3. Design recommendations for the installation
3.1. Recommended power connection
Enelion charging stations are adapted to five-wire
power supply from TN-S type and TT type grid. It is
possible to apply three-wire power supply from TN-S
type grid.
oWARNING
Connection possibilities have been described in
“User manual”, in the Device configuration sec-
tion.
Enelion charging terminal must be powered from the
electrical switchboard. The board must have the re-
quired protections in the form of an overcurrent circuit
breaker with B or C characteristics and rated current
of 32 A or lower, appropriate to the device version. To
be compliant with the PN-EN IEC 61851-1: 2019-10
standard, each charging point must also be protected
against type A or B residual current. This requirement
must be met by one of the below:
1. installation of a type B residual current device
(RCD B 30 mA/40 A) or RCD EV (30 mA/40 A) in
the switchboard,
2. installation of a type A residual current device
(RCD A 30 mA/40 A) in the switchboard with the
application of Enelion RCM B – type B Residual
Current Monitor, attached to the charging termi-
nal.
The final selection of the safety devices belongs to an
authorized designer or a qualified electrician.
HINT
The above requirements result in the neces-
sity to use independent cables for multi-socket
devices: Wallbox Duo Power and Wallbox
Adspace.
INFO
Wallbox Duo multi-socket device allows one to
power the charging sockets only in 1-phase
mode. Therefore, it should be powered with one
four-wire cable.
The cross-section of the power supply cables must be
selected by an authorized electrician, depending on the
distance from the switchboard and other conditions per-
tinent to the location. To obtain the maximum charging
power in wall-mounted devices, the use of cables with a
conductor cross-section not greater than 6 mm2is rec-
ommended. The maximum cross-section of the power
supply cable to be assembled in connection terminals
is 16 mm2. The diameter of the power supply cable
with insulation must not exceed 16 mm2.
Cables running underground must be installed in accor-
dance with the binding building regulations. For conve-
nient installation, flexible power cables, stranded type,
terminated with clamping sleeves are recommended
oWARNING
To supply the voltage to the installed and con-
nected charging station, first switch on the RCD
protection, and next the overcurrent switch.
For installation, about 50 cm of power cable re-
serve from the expected installation position is recom-
mended.
HINT
For Wallbox Adspace devices, a reserve of
about 110 cm of the cable supplying power to
the left socket is recommended.
3.2. Recommended communication net-
work
Enelion devices support the Enelion Chain communica-
tion interface. For its implementation, a wired connec-
tion between the devices is required using an Ethernet
CAT 5 or CAT 6 cable.
For installation, leave about 50 cm of communication
cables from the expected installation position.
The network works in a serial topology where:
• the number of Enelion charging points does not
exceed 100 devices,
• the total length of the communication cable con-
necting the devices does not exceed 500 m.
