Introduction
Product description
The Evnex R-Series charging stations are a cost effective smart charging
solution, available in both single phase 7kW, and three phase 22kW
configurations.
When connected to a compatible OCPP (Open Charge Point Protocol)
server, the Evnex R-Series charging stations become an excellent choice
for smart-grid managed charging or public charging, where energy
metering or access control is required.

Safety information
General information
•This unit should only be installed by those who are appropriately
qualified and skilled to do so.
•This unit has been designed and tested in accordance with IEC
61851-1:2017 and IEC 61851-21-2:2018, however the installer is
responsible for ensuring that all local regulations and standards
are complied with.
•Modifications to this product by anyone other than an authorised
service technician may void the warranty.
•There are no user serviceable parts inside the charging station. Do
not attempt to repair the charging station yourself.
•It is the user’s responsibility to ensure that the cable is stored
safely, and not left where it could become a tripping hazard, or
subject to stress or damage.
•This charging station should only be used to charge a vehicle with
a compatible J1772 socket, or IEC 61851 type 1 or type 2 socket.
Risk of electric shock
•Read all instructions before installing or using this product
•Do not use this product if it appears to be damaged in any way,
this includes fraying or broken insulation on the power cable or any
signs of cracking or separation on the connector or charging unit
•Do not attempt to replace components
•Do not use extension cords or any kind of adapter with this
product
•This product should not be used by children
•Avoid installing this product in locations that are prone to flooding

Site selection
•Consider pedestrians and other traffic, ensure that the charging
cable does not pose a tripping hazard.
•If possible, avoid installing the charging station in a place where it
can be damaged by falling objects, doors, vehicles or machinery
•Although this charger is designed for indoor and outdoor
installations, it is recommended that exposure to rain, snow, hail
and direct sunlight is minimized where reasonable to increase
lifespan
•Do not allow this charging station to be subject to water spray
such as water blasters or high-pressure hoses
•The attachment surface must be sufficiently strong to withstand
normal use, non-tethered versions are subject to extra forces when
plugging and unplugging
•Ensure that the attachment surface is flat - an uneven surface may
warp the enclosure and prevent installation of the front cover
•Consider signage locations for warnings such as “Trip Hazard” if
applicable

Mounting notes
All charging stations (or the storage means for the vehicle
connector in tethered lead models) should be mounted at a
height between 0.4m and 1.5m above ground level.
Sides of the unit are not vertical and should not be used to find
level. The template has flat sides suitable for placing a level
against before drilling. When screwing the unit to the wall, use
the top face of the unit to place a level against.
The mounting locations on the top left and right corners of the
unit are NOT TO BE DRILLED in standard installations. These
mounting points are for non-standard installations and require
additional sealing.

Fasteners
Locate the packet labelled INSTRUCTION MANUAL & FASTENERS
containing the following:
*No.2 square bit required
**Torx T20 security bit required

12
Evnex R-Series Installation Manual | V191002
Opening the unit
Remove the fasteners securing the front cover.
The cover has a tether to decrease
risk of wire strain. This tether can be
looped into the recess in the top right
corner of the enclosure to keep the
cover out of the way during
installation.

13
Evnex R-Series Installation Manual | V191002
Mounting unit
5 x 5mm holes must be drilled in the unit for the mounting screws.
Place the unit on a soft surface such as the box, to prevent marking the
unit while drilling the holes.
Drilling too deep into the unit may cause the chuck of the drill
to damage wires. Remove any plastic swarf from the unit as it
could prevent water-tight installation of the sealing plugs and
the front cover.
The mounting surface must be flat to ensure that the unit is not twisted as
it is fixed against the chosen wall.
A cardboard drilling template is provided to allow easy marking out of the
5 mounting holes.
For timber framed walls, 3mm pilot holes are recommended.
For concrete walls, a 7mm masonry bit is required to allow insertion of the
supplied wall plugs.
The location of the optional rear entry hole (M25 or M32) is also provided,
along with the optional M12 hole location. M12 and M32 holes need to be
drilled by the installer if required.

Evnex R-Series Installation Manual | V191002
Solid wall mounting example
The diagram below shows a cross section of one of the five mounting
holes in a solid wall such as concrete.
For timber framed walls, the screws should enter solid structural framing
inside of the wall. If this is not possible, proper anchoring hardware,
suitable for the wall material and thickness, should be used.
For concrete or other solid walls, use the supplied wall plugs.
Recommended hole depth is 40mm with a 7mm masonry bit.
For all types of installation ensure that the washers are installed on the
screws and that the sealing plugs are installed after the screws are firmly
tightened.

Wiring connection
Always ensure that the main supply is isolated before
beginning work on the charging station installation.
The installer must ensure that the charging station is
correctly earthed.
The R-Series are ‘mode 3’ charging stations. Due to their
high current consumption, they must be connected to a
dedicated feed from the main distribution board.
The R-Series of charging stations are not designed to
charge vehicles that require ventilation systems during
charging.

Upstream protection
The following recommendations are provided as a guide.
However, upstream protection should be installed in
accordance with local regulations.
Residual current protection and a suitably rated means
of overcurrent protection should always be installed
upstream of the charge point at the distribution board.
This could be an MCB installed alongside an RCD or an
RCBO.
To avoid the requirement for more expensive type B RCDs, all R-Series
charge points have a 6mA DC current detection device (Residual Current
Monitor) built in. This is to prevent the blinding of type A RCDs from
potential DC leakage currents. In the event of detecting a DC leakage
current, the charge point will immediately stop the charging session and
transition into a fault state, requiring a reboot to clear the state.
If local regulations require, a type B RCD can still be safely installed
upstream.
The RCD must comply with one of the following standards; IEC 61008-1,
IEC61009-1, IEC 60947-2 or IEC 62423
The Circuit breaker must comply with one of the following standards; IEC
60898-1, IEC 60947-2 or IEC 61009-1.
The RCBO must comply with IEC 61009-1.
