Safety information

Warning: The supplied BG SyncEV charger
is manufactured to be safe without risk
provide they are installed correctly, used, and
maintained in accordance with the manufacturers
recommendations and installed by a competent
electrical installer in accordance with national
and local regulations and legislation applicable
at the time of installation, e.g. BS7671:2018
amendment 2.

The EV Charger is suitable for use with a single
phase (for up-to 7.4kW charging) 220-240V
Nominal AC supply.
The supply should run from a dedicated 40A
circuit breaker. We recommend the use of a Type
B curve circuit breakers. The EV charger features
an integral 30mA type-A RCD with 6mA DC
leakage detection and therefore an external RCD
is not usually required:

1. For cables without earthed metallic covering

installed in walls or partitions at a depth of
less than 50mm and also within walls and
partitions with metal parts, and not protected
by steel conduit or similar then RCD
protection is required.

2. If the cable is clipped directly to the surface

of a wall and does not pass through a wall or
partition to the EV charger then a standard
B type 40A MCB may be installed into the
Consumer unit, however RCD protection
may be required for other reasons such as
if it forms part of a TT system and the earth

Return to Contents

fault loop impedance values cannot be met.
This will be in compliance with the current
BS7671 Amendment 2 Wiring Regulations.
To conform with BS 7671, on occasions a two
pole MCB/RCD or other means of isolation
may be required.

Important note: A DC Leakage fault in the
vehicle may “blind” a type “AC” RCD and render
it ineffective, never feed any EVSE From an
upstream Type “AC” RCD.

Earthing requirements

The supplied EV charger features an on-board
safety monitoring system to detect low or high
voltage supplies and potential earth-neutral faults,
this in accordance with regulation 722.411.4.1
(iv) of BS7671 2018. If such a condition is
encountered the charge cycle is ended or
prevented and the EV charger indicator flashes
red and effectively becomes a double insulated
(class II) device. The vehicle becomes isolated
in accordance with Regulation 543.3.3.101(ii)
from incoming supply and poses no risk to
touch. This feature removes the requirement for
an earth electrode where it may be ineffective or
introduce further risk.

The EV charger may be connected directly
to a TN-C-S (PME) earthing system without
any special arrangements. It remains the
responsibility of the installer to conduct a risk
assessment of the immediate area to a range
of 10 meters (equipotential zone) to ensure no
other conductive metal fixings pose risks (mixture

Return to Contents

of TT/TN-S and TN-C-S), this is important where
cable length may enable charging inside or
outside of a building/garage where the vehicle is
within touch distance.

Where certain conditions dictate an earth
electrode must be used it shall be independent
from the distributors earth system with no direct
interconnection (the incoming supply SWA
protective earth should be isolated from the
housing and/ or earth electrode). The electrical
installer shall install a suitable electrode complete
with termination housing and covers where
appropriate, warning labels should be visible
and close to the unconnected SWA protective
earth, e.g. inside the charger.

The earth connection shall be made from the
electrode to the charger via copper conductor
earth wire of an appropriate CSA for the
installation. The earth wire shall be installed
in conduit where there is a risk of mechanical
damage or UV exposure. Recommended Earth
electrode impedance to be <100 ohms.

Return to Contents

Surge protection

Guidance on requirements for surge protection
devices given In BS7671: section 443.

The EV charger is protected against transient
over voltages (+/-2kV Line-Earth and +/-1kV Line­Line as a requirement of EN 61000-6-1), a direct
lightning strike carries a current of 30~ 200kA
the EV charger’s internal protection would
provide little or no protection in such an event,
likewise nor would an SPD rated less than 30kA.
If life support equipment or business operations
could be affected by a lightning strike central
SPD protection is advised if it does not already
exist.

The guidance on risk calculation in section 443.5
of BS7671 in most cases is not possible due
to unknown location of any SPD already fitted,
length of cables to calculate LP etc, it is therefore
recommended a common sense approach is
used on choice of SPD (or if required).

Return to Contents

Isolation and switching for safety
and maintenance

To ensure the EV charger can be “turned off”
to enhance security and enable maintenance
activities, a two pole isolator (or DP RCD or
RCBO) suitably rated must be installed within the
customer’s property.

An isolator switch is a mandatory requirement for
“new builds”, but optional for existing dwellings
(at customer’s request), the switch should be
mounted between 500mm and 1500mm above
finished floor level to comply with regulations.
The switch should be rated at 45 Amps.

All installations must comply to BS7671: 2018.

Return to Contents

Installation requirements

The EV charger is suitable for installation inside
and outside on a solid wall or structure.
The installer should consult with the building
owner to establish their preferred installation
location. This should take into consideration
the length of charging cable and risk of vehicle
impact etc.

It is recommended the charger is installed at
a height of 500mm-1500mm as per building
regulations BS8300:2018.

If no suitable permanent structure is available,
the EV charger can be mounted to a stand.
We recommend of the BG SyncEV stand,
EVASTAND12S (single) or EVASTAND12T (twin).

Ensure suitable fixings are used depending on
the mounting surface. To avoid unnecessary
dust inside the enclosure, it is recommended to
use the included fixing hole template drill the
surface, before fitting the enclosure.

Ensure installation wall has been checked for
electric cabling or pipework with a suitable
detector.

NOTE: if any groundworks are required e.g.
cable trenching or earth electrode fitment, it is
advisable to check if underground services could
be present before commencement. Plans may be
available at: www.linesearchbeforeudig.co.uk
(free to domestic users).

Return to Contents

The EV charger is suitable for bottom or rear
cable entry, if using rear cable entry ensure
the included 25mm rubber grommet is used to
maintain the IP rating.

If using SWA cable the included 25mm
compression gland is NOT suitable, an
alternative gland will be required.
When using SWA please supply the charger
from the bottom left cable entry point.
A maximum hole size of 32mm is acceptable
at this location. Its advisable to earth the SWA
armouring at the supply end of the cable.

Do not drill alternative cable entries into the
charger housing, except marked cable entry
location for rear or bottom entry.

We recommend using BG SyncEV Power &
Data Combined cable on installs that require
a CT clamp to use the chargers dynamic load
management capabilities.

All of the cables that are to be connected in to
the supply connector should have their insulation
striped back 18-20mm. Connectors supplied are
suitable for cables of 4-10mm².

Return to Contents

Load balancing

If load balancing is required, a CT clamp should
be used for correct balancing. One BG SyncEV
CT clamps, EVA120CT1, is supplied in the box
with this charger. This should be fitted around
the incoming power to the main fuse and the
correct max load (A) to be entered during setup
and installation steps.

Locate the main incoming power cable

1

into the property. The CT Clamp needs to
be fitted before any of the tails are split
for correct measurement.

Open the CT Clamp and fit around the

2

incoming Live power cable, this is typically
marked brown for most installations.

Ensure the Arrow is pointing into the
property from the incoming fuse.
K towards Source, L towards Load.

External Mid Metering - RS485

If using an external Mid Meter connected via a
RS485 connection the Dip switches need to be
set. Dip 2 Up/On is required for external Mid
Meter use.

Final Electrical testing

To meet the BS7671:2018 (18th edition)
requirements for testing of an electrical
installation, the following tests and checks shall
be performed by a competent electrical installer
before during and after a BG SyncEV charger is
installed:

• A visual inspection of the installation

including the existing electrical installation.

• Verification of the characteristics of the

electrical supply at the origin of the
installation to confirm the supply is suitable
for the additional load.

• A test to confirm the continuity of the circuit

protective conductors.

• A test to confirm the integrity of the circuit

insulation resistance.

• A test to confirm the polarity of the

installation is correct.

• Where applicable a test to confirm the earth

electrode resistance is within acceptable
tolerances.
(or)

• An earth loop impedance test.

Return to Contents

• A test of the mechanical operation of

residual current devices (RCD’s).

• A test to confirm the operation of residual

current devices (RCD’s) is within stipulated
time scales (at the rated current and at five
times the rated current operating current).

• A test or calculated measurement of the

prospective fault current.

• A verification of the functional operation of

the EV charger.

• An electrical installation certificate must be

completed.

Ensure electrical testing is done before EV
charger commissioning and network setup is
performed.

For this testing, the Charger can be set to “Plug
