Locating the unit - To operate fully, the VEVA must have a Wi-Fi connection. Before in-
stalling, check the chosen location has good signal strength to the users Wi-Fi network.
• Check for a Wi-Fi signal at the installation location using a mobile phone.
• If the network cannot be found, a suitable Wi-Fi extender must be installed.
• The VEVA unit operates on 2.4GHz Wi-Fi networks only
1. Fit Cable Protector. When installing a tethered unit
against a rough wall, t the Cable Protector Plate. The
plate helps prevent chang of the charging cable
against the wall when stowing around the unit. The
plate may also be used to aid cable stowage when using
a mounting post. Screw the plate to the rear of the unit
using the screws provided.
2. Remove the front fascia. Loosen the two screws tted
along the bottom edge of the fascia (no need to remove)
and lift the cover away from the base . Remove cover by
pulling upwards and unhooking at the top edge .

7
5. Fix the unit to the wall.
• For wall mounting - use the top xing hole together with right and left lower holes.
For post mounting - use the top hole and two centre vertical holes (undrilled).
• To x, it is recommended that the top xing hole is marked, drilled and the unit
screwed loosely to the wall. Using the built-in spirit level, align the unit vertically
and mark the two remaining xing holes. Rotate the unit to the left and right around
the top xing point to allow the drilling of the xing holes.
 Alternatively, use the wall xing template provided.
When drilling, ensure dust is prevented from entering the unit.
• Ensure the base is not distorted after xing. If tting against an uneven wall, the unit
may be levelled using the round spacers (supplied). Reduce any gaps by tting
spacers over the xing lugs in the base as required.
• When screwing to the wall, always t the sealing washers (supplied) below the
screw head to maintain weatherproong integrity.
• Any unused xing holes must be sealed with bungs (supplied).
4. Install cable entry. Select one of the
six possible cable entry locations
shown opposite.
• When cable entry is from the back
of the unit, use the cable grommet
supplied (not the gland).
• Cut a 25mm hole to t either the
cable gland or grommet.
• Take care to ensure that the
weatherproof rating of the unit is
maintained during this step.
• Cable entry at any other location
than those shown is prohibited.

6. Wire the unit as per page 8, 9 and 10.
7. Ret Front Cover. Check the Main Seal is undisturbed and rmly in place, then ret
the front cover. Secure the cover with the captive screws ensuring each screw is still
tted with a seal. Take care not to distort the cover when retting, tighten each screw a
little, in turn. Do not use a power driver. Screws must not be tightened over 1 Nm.
8. Commission and test the unit as per the later sections. Replace the front fascia.

SUPPLY
The VEVA unit should be connected to a 230V nominal AC supply using a cable with a
conductor CSA suitable for the installation run, and selected according to the current
wiring regulations.
The supply should be run from a dedicated 32A*1 circuit breaker to provide isolation and
overcurrent protection. It is recommended that Curve C circuit breakers are used. An
RCBO with equivalent rating and characteristics may be used.
*1 The unit may alternatively be supplied from a 16A circuit breaker, however the unit
must be downrated to 16A maximum output using the Engineering function of the VEVA
app, see page 13.
The unit has inbuilt 6mA DC fault protection and a 30mA Type-A RCD *2.
*2 Although the unit has inbuilt RCD protection, to meet current wiring regulations the
tting of an additional external 30mA Type-A RCD is also required.
Further isolation of the supply to the VEVA unit may need to be provided. An isolator
switch is mandatory for new builds but can be installed at the customer’s request for
existing dwellings.
All installations must be compliant to BS7671:2018.
CONNECTION
Insert the supply cable through the installed cable
gland or grommet and ensure that the cable has
sufcient length to reach the terminal blocks.
All cables that are connected to the supply
terminals shall have their insulation stripped back
8 to 12mm.
When connecting the VEVA unit, the supply
terminal block is clearly labelled Live, Neutral and
earth. Connect as shown opposite. Recommended
tightening torque of supply terminals is 1.5 Nm.
It is recommended to use a combined power and
data cable designed for the connection of EV
chargers. Further information on the connection of
the measurement clamp is provided in the next
section.
WIRING THE UNIT

9
The VEVA unit features on-board safety monitoring to provide protection to the user
against electric shock in the event that the PEN conductor becomes damaged or
disconnected. The unit continuously monitors the incoming supply to detect problems
with the PEN conductor, and if so, automatically disconnects the supply to the output of
the charger. The vehicle becomes isolated from the charger meaning there is no risk of
electric shock.
EARTH RODS
The VEVA unit is compliant with regulation 722.411.4.1(v) of BS7671:2018-amd1: 2020
meaning when directly connected to a TN-C-S (PME) earthing system, an earth
electrode is not required.
Where certain conditions dictate that an earth electrode must be used e.g., the
installation is part of a TT earthed system, it shall be independent from the distributors
earth system. The earth connection shall be made via copper conductor earth wire of an
appropriate CSA for the installation. It is recommended that the distributors earth
system is terminated at the input to the charge point to provide further protection
against mechanical damage to the incoming supply cable. It remains the responsibility
of the installer to conduct a risk assessment of the immediate area to ensure no buried
objects pose risks to the earth electrode.
EARTHING ARRANGEMENTS

10
INSTALLING THE MEASUREMENT CLAMP
Warning: Do not t the clamp around supply cable before wiring to the terminal block.
High voltage can be generated across unterminated clamp conductors.
The measurement clamp must be tted if Charging by Solar or the dynamic Demand
Control functions are to be used.
The measurement clamp is a sensor used to monitor the current owing to, or from, the
grid. The clamp is installed around the live meter tail between the main electricity
meter and consumer unit.
1. Identify clamp tting position. The clamp must be tted on the live cable between the
main electricity meter and the consumer unit. If the live supply has been split with a
connector block, the clamp should be tted between the meter and block.
2. Wire the clamp to the VEVA unit. The measurement clamp is supplied with an 8m
cable with Grey and Black conductors. Depending on clamp version, a third shield wire
may also be provided. Install the cable then connect the conductors to the small
terminal block (Grey to G, Black to B), as shown. If provided, connect the shield wire to
the earth terminal.
If the cable needs to be extended, or if using
the data cable within a combined data and
power supply cable, shorten the clamp cable
and connect to the data cable using the
miniature junction box (supplied).
Note: To prevent interference, any
additional cable used must be either twisted
pair or shielded, twisted pair cable e.g., CAT
5 data cable. Failure to use a correct data
cable will cause distortion to measurements.
Where using a shielded data cable, the cable
shielding must be connected to the earth
terminal of the VEVA connector block. It is
good practice to protect the exposed copper
shield with a small length of sleeve.
3. Install clamp. Open the measurement clamp and position around the previously
identied supply cable, observing the correct orientation marked on the clamp. Close the
clamp around the cable and ensure that the latch is engaged.
The commissioning process will check that the clamp has been tted correctly. If the
clamp has the wrong orientation, this can be corrected automatically without needing to
change the installation using the Engineering function of the VEVA app, see page 13.

COMMISSIONING PROCESS
To commission the VEVA unit, you will need to download the VEVA app...
1. Search for VEVA in the App Store or on Google
Play and install the app onto your smartphone
There is no need to create an account.
2. Using the Engineers commissioning section of the App (see below), connect to a Wi-Fi
hotspot created by the VEVA unit, after pressing the pairing button
3. Congure the installation settings
4. Test and check the VEVA unit is operational and running correctly
5. Connect the VEVA unit to the homeowners Wi-Fi network (this can be skipped if the
home is a new-build or if the homeowner prefers to do this themselves)
The process is detailed in the following sections...
1. USING THE VEVA APP
When rst using the app, it may request you to accept Location
Services. Accept the request as this may help when connecting
the unit to the homeowners Wi-Fi later. Additionally, if using an
Apple smartphone, if possible, connect your device to the
homeowners Wi-Fi network. Again, this will help if connecting
the VEVA unit to Wi-Fi later. However, ensure the network is a
2.4GHz Wi-Fi network (the VEVA unit will only connect to
2.4GHz networks). If in doubt do not connect to the Wi-Fi.
To use the commissioning tool, go to the ‘Get Started’ page and
select the Engineers Section as shown highlighted, right.
• There is no need to create an account; a login name or
password is not required.
• The App will guide you through the process.
Move through the pages until you are asked ‘Connect to your charge point rst’, then
follow the next pages.
COMMISSIONING AND TESTING
Before commissioning, the installer must carry out sufcient checks to ensure the
installation is compliant with the requirements of BS7671: 2018.
Electric Vehicles (Smart Charge Points) Regulations - At the point of sale, the charge
point is set to charge only during off-peak hours. To commission the charger, settings
can be briey overridden whilst the charger is in installation mode, allowing sufcient
time to perform the required functionality tests described below.

12
2. CONNECTING TO THE VEVA UNIT
1. Push the Wi-Fi pair button.
With the front fascia removed, power up the unit.
Push down on the Wi-Fi pairing button and hold
for two seconds. The ring light will change
colour to yellow to indicate the unit has entered
installation mode.
2. Connect to the VEVA Hotspot.
The VEVA unit will create its own temporary Wi-Fi
hotspot named VEVA, plus the last 4 digits of the serial
number.
Go to the Wi-Fi Settings page of your smartphone and
select the VEVA hotspot from the list of networks found.
Your smartphone will connect to the unit’s Wi-Fi hotspot.
Return to the VEVA App.
3. Connected.
When returning to the VEVA App,
it will automatically connect to the
VEVA unit and conrm on the
screen.
If the App does not connect, return
to the home screen and retry the
process. Try turning off mobile
data or disable Wi-Fi assist.
Select ‘Go to charge point settings’
and continue to the next section.
Pairing
button
The commissioning process is carried out by connecting your mobile device to a Wi-Fi
hotspot created by the VEVA unit. Connection is simple as follows...

13
If the reading is unstable, too high or too low, this could be
the result of the wrong cable being used to extend the clamp cable, poor cable shielding
or not connecting a shield to earth at the VEVA unit.
Solar Systems - Ensure the direction of current ow is as expected. Try switching on a
high power device and checking ow direction, if possible charge an EV. Battery storage
systems attempt to zero current drawn from the grid and may cause reading confusion.
4. Check measurement clamp is reading correctly, if tted:
Using the Total Household Current value, ensure the
measurement clamp is tted in the correct orientation and
the reading is stable (-ve value means current is measured
as exporting to the grid). If required, the value can be
inverted using the Invert measurement clamp value
selection (saves retting the clamp).
3. Congure settings for the installed unit:
• Current measuring clamp tted – Select whether a
measurement clamp has been tted, yes/no.
• Demand Control Supply rating – Enter the properties
fuse rating (only applicable if a clamp is tted).
• Charge point maximum output current – Congure the
maximum output of the charge point (16 or 32A),
depending on the rating of the supply circuit.
• Earth rod tted – Select if an earth rod was required for
the installation, yes/no.
5. Check Supply Voltage.
Check the Supply Voltage value and ensure the value is within 230V AC ± 10%. If not, an
earth rod may be required (and congured as installed in the above settings) to allow the
voltage limits to be raised to 230V +12% / -10%. If the voltage is still outside of the limits,
the local Distribution Company (DNO) may be required to resolve the issue. Overvoltage
will cause nuisance fault tripping of the charge point.
For functional testing, pressing the Activate 30-min Boost button will enable charging:
• Conrm charge point operation with EVSE test adapter
• Conrm the operation of the RCDs is within stipulated timescales
• Verify charging operation with customers vehicle
• If connecting a car, check Charge point Current to ensure charging is at correct rate.
3. SET UP AND ELECTRICAL TESTING
4. FUNCTIONAL TESTING
Using the Charger Settings page, set up and test the following...

14
5. Wi-Fi SET UP
After all tests are completed, the VEVA unit may be connected to the homeowners Wi-Fi
network. From the Charger Settings page, select “Connect charge point to Wi-Fi” to con-
tinue with Wi-Fi set up or “Skip Wi-Fi setup” if you are unable to do so at this point.
To set up a Wi-Fi connection follow as below...
If a network is not suggested, type in the SSID of the
network to be used, together with password, see left.
1. Select the Wi-Fi network and add password, the VEVA unit
should connect to and operate on:
Android devices — See right, select the desired network from the
list of networks found. Enter the Wi-Fi password at the next page.
Press Join and the VEVA unit will attempt to join to the Wi-Fi
network selected.
2. Check that the VEVA unit has successfully joined the network.
The ring light will indicate whether the unit has successfully joined the network (the
right half of the ring indicates Wi-Fi connection, the left half indicates
connection to the VEVA cloud). Check the nal colour as follows:
All Green
The unit has successfully connected to the Wi-Fi network and can
communicate with the VEVA cloud. Installation is fully complete.
All Red
The unit has not connected. This could be :
• An incorrect password or SSID name was used (both halves Red);
• Insufcient Wi-Fi signal strength at the VEVA unit (both halves
Red), a Wi-Fi extender may be required in this case;
• No internet connection and the unit cannot communicate with the
VEVA cloud (initially right half of ring shown Green, before fully
turning Red). This indicates Wi-Fi has connected but no internet);
Check the internet connection and retry the Wi-Fi set up.
Apple iOS devices — Privacy rules prevent
a list of networks being shown. However,
if Location Services have been accepted
(when rst using the App) and the
smartphone is connected to the
homeowners Wi-Fi network, the App will
automatically suggest the Wi-Fi network
you were connected to and just require
the password.
