Overview and Intended use environment
The Smart PRO can be classied as a ‘smart’ electric vehicle charging solution because of
its communications infrastructure which allows charging to be remotely optimised by the
Indra App; where charging can take place when electricity is cheapest; or if immediate
charging is required, its ‘Boost’ functionality overrides any smart grid criteria and provides
instantaneous charging capability.
Charging using the Smart PRO can take place at up to 7.4kW, but due to modulation
capability (measured by the external CT clamp) this power output level can also be reduced.
The Smart PRO is intended for both indoor and outdoor installation, securely mounted to a
wall or appropriately design pedestal.

O-PEN Fault Detection
The Smart PRO has built in O-PEN protection in the form of Indra’s patented PESTs. This
oers multiple options to comply with the PEN fault regulations, including Line to Neutral
Voltage monitoring (PEST mode B) and CPC to true earth voltage monitoring (PEST mode A).
House Fuse Protection (Load Curtailment)
Is a function that allows an EV charger to be installed at a property that may not have
enough spare power capacity to accommodate the charger always operating at full capacity.
It works by monitoring the amount of power the installation is using via an external CT clamp
and comparing that to the rating of the main fuse supplying the installation. If the dierence
is greater than 32A then the charger will oer full charge. If the dierence is less than 32A
then the charger will only oer as much power as there is spare capacity.
Note: G100.2 denes how load curtailment is managed. If the charger is congured to use
load curtailment and it loses contact with the External CT clamp, then the charger will
de-rate its power output to 6A to protect the main cut-out, thus 6A is the gure that should
be considered when carrying out the maximum demand survey.
DC Leakage Protection
An RDC-DD is tted into the Smart PRO oering 6mA DC leakage protection. This means the
Smart PRO can be installed with a Type A or Type F RCD up stream.
Over-The-Air Updates
The Smart PRO can be updated remotely while connected to the internet . These updates
can oer improvements to the function of the charger, be pre-emptive xes for known
issues, or used to rectify faults if they occur.
Tari Intelligence
Indra Smart Chargers can optimise charging based on the customer’s tari, where they have
a time of use tari. We support any time of use tari including Octopus Agile. For more
information follow this link here.

8 Indra Smart PRO Installation Guide
Solar Mode
This mode can be selected in the Indra App and can enable the customer to use surplus solar
energy (or any other form of micro-generation) to charge their car.
The external CT monitors how much energy is being exported from the installation. If the
installation is exporting more than 1.4kW , then the charger will oer the car a charge.
(1.4kW is the minimum amount of power required for all in-car chargers to accept a charge).
Note: The external CT clamp can only measure what energy is being exported back to the
grid, therefore, if the micro-generation is generating 2kW, and the installation is using 1kW,
the charger will only detect the remaining 1KW being exported to the grid. This means the
charger will not oer a charge to the car because there isn’t enough power to trigger the
in-car charger (1.4kW). Export to the grid needs to be 1.4kW or greater before the car will be
oered charge.
Smart Scheduling
Smart scheduling enables the user to create a schedule window, this is when the charger will
start and stop charging, but also, how many miles to add, how many kWh to add or how much
money’s worth of energy to add to the car.
Charge Analytics
The Indra App allows the user to control the charger, use the boost function, set charging
schedules, etc., and provides detailed information on their charging behaviour and their
charging history, including how much money they have spent, and how many miles-worth of
charge have been added to the car.

PEN Fault, Earthing, Simultaneous Touch
(PESTs) ProtectionProtection
The Smart PRO PESTs solution can operate under four of the indents of BS 7671:2018
A1:2020+A2:2022; section 722.411.4.1, for the purposes of design/installation we have
two modes of operation which Indra call A & B. Mode A can be congured with or
without a reference electrode. The safest installation conguration is, mode A with
reference electrode.
• Mode A with reference electrode – Indent iii – PME (Protective Multiple Earthing) as
CPC with a reference electrode and the only method for compliant install on a 3-phase
installations. Using this method negates nuisance tripping from uctuating supply voltage.
• Mode B – Monitors the L-N voltage and will disconnect from the car if the voltage goes out
of range (253V-207V). PME is used as CPC and no earth rod or reference electrode is required
if there are no simultaneous contact or touch voltage risks present. Consideration should
be given to nuisance trips where the line to neutral voltage may regularly exceed 253v,
especially where local solar panel or other forms of micro-generation are present.
• Mode A without reference electrode – For installations that do not fall under the
requirements of 722.411.4. E.g.E.g., TT installations, indoor installations, installations where
PME is bonded to Earth in accordance with indent ii.
PESTs Mode A essentially works by comparing three voltage readings:
1. L - N (Disconnects above 257.6V and below 184V. 230v +/- 12%)
2. L - Ref Electrode (Disconnects above 257.6V and below 184V. 230v +/- 12%)
3. CPC (PME) – Ref Electrode (Disconnects above 30v RMS)
• Mode A without reference electrode – For installations that do not fall under the
requirements of 722.411.4. E.g., TT installations, indoor installations, installations where PME
is bonded to Earth in accordance with indent ii.
PESTs Mode A essentially works by comparing three voltage readings:
1. L - N (Disconnects above 257.6V and below 184V (230v +/- 12%)
2. L - Ref Electrode (Disconnects above 257.6V and below 184V (230v +/- 12%)
3. CPC (PME) – Ref Electrode (Disconnects above 30v RMS)

Pre-Installation Survey
Before installing an Indra Smart PRO, we recommend surveying the installation to ensure
that an install can go ahead and that the Smart PRO is appropriate for the requirements.
Therefore, you should:
• Identify the earthing arrangement of the property and the required PEST mode that
will be required.
o If a reference electrode will be required, identify a suitable location for it.
• Establish the maximum demand of the existing installation and compare this with
the rating of the main cut out supplying the property. If there is less than 32A
capacity remaining, then the Load Curtailment (House fuse protection) feature on the
Smart PRO will be required.
o If Load Curtailment or Solar Mode is required by the customer, establish where
the external CT would be placed.
• Identify which connectivity method would be most appropriate.
Installation Procedure
The Smart PRO is supplied with the screws and wall xings that are required to permanently
x it in position. However, it remains the responsibility of the installer to evaluate the
suitability of the installation surface and use the appropriate xings for each install.
• All parts of the existing installation that will comprise part of the EVSE charging
circuit, MUST be inspected for damage, suitably rated and compliant with the
appropriate regulations.
• Ensure the installation earthing conductors are tested and compliant with BS
7671:2018 A1:2020+A2:2022
WARNING: ANY DAMAGED OR UNSUITABLE CABLES OR EQUIPTMENT MUST BE REPLACED
• Inspect the Smart PRO to ensure the charger has not been damaged in transit and is
safe to connect.
14 Indra Smart PRO Installation Guide

15
Switchgear
The Indra Smart PRO does not have in-built RCD protection, which means it must be tted
upstream. Indra recommends installing the following to minimise potential nuisance
tripping and to ensure compliance with BS7671:2018 A1:2020+A2:2022 section 722. (These
requirements can be met in whatever conguration suits your design.)
a) Type A 30maA Double Pole RCD protection
b) C Curve 40A Overcurrent protection
In accordance with BS 7671:2018 A1:2020+A2:2022 Regulation 443.4.1, a surge protection
device will need to be installed to protect the charger unless the customer has signed a
waiver acknowledging they accept the risk of any potential damage caused.
Choosing the charger Location
• Select an installation location that ensures future servicing of the Smart PRO, where
the back plate can be mounted ush to a at wall and screws can be used to
permanently secure the charger in position.
• Make sure the install location will not allow any ammable material to come within
100 mm of the unit.
• The control panel of the unit should be installed between 0.75-1.20m from the ground.
• The charger should be placed such that the potential risk of tripping over trailing
charging leads is minimised as far as reasonably practicable.

Wall Mounting
Note: The xing holes in the bracket are spaced to meet standard brick sizes so they can all
fall within a brick centre.
• Oer the mounting bracket against the surface you intend to x to and level using a
spirit level
• Mark and drill four holes with a 6 mm drill bit (Masonry/+.5mm Plasterboard)
• Fit the supplied wall plugs into the holes and secure the bracket with the four screws
supplied.
Hanging the charger
• Hold the top of the charger just above the wall bracket tilted upwards away from the
wall
• Lower the charger onto the two prongs at the top then hinge the charger back ush
with the bracket
• Secure the charger to the bracket by tting 2 x 4x8mm button head, T20 Torx screws
into the bottom of the charger with a T20 screwdriver. Torque setting 2.0-2.5 N/m.
• Carefully remove the front of the charger and hinge it to the side to allow access, the
front body Is secured to the main body to protect the ribbon cable to the front panel.

Cable Entry
The Smart PRO is designed with four cable entry points, two in the bottom edge and two in
the rear (Identied in blue on Fig 01).
• Cable entry point 1 is designed for a 25mm hole
• Cable entry point 2 is designed for a 20mm hole
• The rear entry points are designed for a 25mm hole
• Install the appropriately sized IP68 rated gland for the cable used, or, for rear entry,
enter using a method that will ensure the IP rating of the enclosure.
All swarf and shavings should be removed from the charger and the hole deburred.

Connect Mains Cables
• Remove the outer insulation of the cable, leaving 10mm showing at the gland
• Cut the cables to approximately the following lengths:
o Live – 200mm
o Neutral – 200mm
o CPC – 240mm
o Data Cable (For CT only) -180mm
o Data Cable (For Internet) – 400mm
• Route the wires as per Fig: 02
• Insert wires into the lever type connectors labelled L (Live), N (Neutral) and CPC
(Circuit Protective Conductor)
Note: Indra recommends the use of bootlace ferrules on class 5 & 6 cables ONLY
Note: Indra recommends using EV Ultra Cable from Doncaster Cables as is contains
power and data in the same cable.

Installing a Reference Electrode
When operating under PEST mode A, a reference to true earth may be required to protect
against O-PEN faults in the distribution network. This reference allows for voltage to be
measured between the installation earth (CPC) and true earth, so that if CPC becomes live
because of a broken PEN this will be detected and the charger will disconnect Live, Neutral
and CPC from the car.
The reference electrode is NOT serving as a fault path, thus does not need to comply with
the requirement for a TT earth electrode.
The reference electrode should be a copper plated 3/8” electrode with a lug terminal clamp.
• If installing straight into soil or equivalent soft terrain, then the electrode can be cut
down, to reduce the necessary length driven into the ground (as short at 300mm). For
hard aggregate, the full four-foot length may have to be maintained.
Before driving the electrode into the ground, ensure there are no buried services in the area.
• Using a lump hammer, or similar, drive the electrode straight into the ground. Leaving
enough length at its tip to secure the clamping terminal.
• Attach the lug clamp terminal and run a length of cable (clipping against walls where
necessary) back to the Smart PRO unit; terminate in the lever type connector labelled
“REF”
Note: Indra recommend the use of Solar PV cable (EN5061) with double insulation
• Using a Multi-Function Tester or electrode tester, measure the resistance of the newly
installed reference electrode and ensure it is less than 600Ω.
