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 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 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.

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 Line-Line 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).

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.

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).

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.

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 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 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.
• An earth loop impedance test.
• 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 and Charge” Mode in the installation App.
