Introduction
This document is designed to
complement the EO Academy
training and does not replace
any onboarding or online
academy certications.
It is still mandatory for installers
to have made contact with our
onboarding team as not do so
can aect product warranty and
help via the support desk.
The details of all EO Academy
training can be obtained by

Experience has shown that
often the most dicult part
of the installation is enabling
the communications between
the EO Hub and the EO Cloud
back oce portal. Therefore
it is recommended that the IT
settings (section 3.13, pg. 22)
are discussed with the customer
soon as possible.

The installer should select the
RCD and earthing conguration
in accordance with the IET
Code of Practice and local
regulations.
Note:Where the EO Genius
includes DC leakage protection
(DCL) a Type A RCD can be
tted at the supply. Otherwise
a Type B RCBO or equivalent
should be used. EO recommend
a dedicated 40A supply rated
circuit for each charging station.

EO Hub Connections
The EO Hub has the following
connections as shown in the
diagram below:
Install the EO Hub in a suitable
indoor location close to the
output of the electricity meter.
Physically mount it to the wall
using the mounting holes and
four appropriate screws (not
included).
An RJ45 connector cable is
provided to start your serial line
and should be connected to the
serial comms port of the EO
Hub.

Pin 3 – Unused but connected to GND
Pin 4 – Comms A – Blue
Pin 5 – Comms B – White with blue stripe

Use the short link, provided, to
make the initial connection from
the EO Hub to serial line RS485.
If not using the link provided we
recommend the use of a Wago
style connector for this purpose.
We recommend you us ethe
Belden 9841 as the serial line.
DO NOT use CAT 5 or 6 cable
as serial line type or you will nd
issues with data transfer.
DO t ferrules to ends of serial
wires if when using Wago
connectors.

Each Genius charge point
has a short length of cable
protruding from it. This needs
to be connected to the other
stations in a ‘Daisy Chain’ format
to eventually terminate at the
EO Hub.

Wago Connectors
Wiring connections
for EO Genius and
the serial bus.
To facilitate serial line connections
we recommend the use of Wago
style connectors as seen here
and also recommend using similar
enclosures as seen on the right
hand side.
Figure 6

With the data bus connection at
charge points it’s time to create
your RS485 connections ‘daisy
chain’ back to the EO Hub. We
recommend Belden 9841 600v as
it carries the best properties for
this application. DO NOT use Cat6
type cable for this application.
Remember to t ferrules where
serial wire has been stripped for
connections.

Main Serial Line (Belden 9841)
Wiring connections
for EO Genius and
the serial bus.
Figure 7

The serial connector on the hub
is an RJ45 socket i.e. a standard
Ethernet socket. The thickness of
the recommended Belden type
cable is too thick to be connected
into the RJ45 connector therefore
a short 30cm Ethernet cable can
be used as the EO Hub’s primary
connection.
Connecting the Serial cable to the
RJ45 connector on the EO Hub:
1. Use the enclosed RJ45 to serial line
adaptor.
2. Take a standard CAT 5 Ethernet
cable.
3. Cut a short length with the RJ45/
Ethernet plug on one end.
4. Strip and expose the bare wires for
pins 4&5 for Comms A&B and pin 1
for earth.
5. Connect the serial cable to the bare
wires using a 3 way level connector.

Resistors are used, in this
case, to increase eciency of
data transmission and reduce
any possibility of noise and
interference.
Considerations should be
observed when creating your
serial line topology.
Both examples opposite are
correct due to the placement of
both termination resistors.
In both examples, resistors are
placed at both ends of the serial
line.
Resistors should bridge both
comms A & B wires.
3.07
To ensure a reliable
communication on the RS485
serial cable, a 120 ohm 0.25W
terminating resistor must be
tted at each end of the serial
line, eectively bridging both
serial wires.
