INTRODUCTION

This guide is intended for use by competent electrical installers to explain basic requirements and options to be considered when installed a BG SyncEV charger. The unit is designed for installations inside or outside, the advanced safety technology we have built into the unit ensures its safe usage. This guide provides information to assist when installing the EVT7 charger and should not be used with other EV chargers.

Installation Requirements

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 single phase EV charger should be connected to a 230V/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. This can be achieved by using the BG IP65 EV protection enclosure (CFEV1A) when mounted next to the existing consumer unit as it includes a double pole 40A 30mA Type A RCD device to protect the circuit. This can be used if the cable has no mechanical protection where it passes through walls and partitions and if the cable is buried within the ground before reaching the EV charger. This will be in compliance with the current BS7671 Amendment 2 Wiring Regulations.
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 double 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.
The EV Charger is pre-wired with 7.5M of cable, this should not be extended with the use of adapters and only used with the cable provided.

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 (Compliant on single phase supplies only). If such a condition is encountered the charge cycle is ended or prevented and the EV charger indicator goes red and effectively becomes a double insulated (class II) device. The vehicle becomes isolated 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. Additional note: BG SyncEV recommend 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 double 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

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 blanking plug supplied is fitted to the open bottom cable entry hole. If using SWA cable the included 25mm compression gland is NOT suitable, and an alternative gland will be required. Do not drill alternative cable entries into the charger housing, except marked cable entry location for rear entry.

BG SyncEV recommends using EV-Ultra™ – Power & Data Combined cable on installs that require a CT clamp to use the chargers dynamic load management capabilities. Please see: www.doncastercables.com/uploads/EV- Ultra_Datasheet.pdf

All of the cables that are to be connected into the supply connector should have their insulation striped back 18-20mm. Connectors supplied are suitable for cables of 4-6mm² and suitable for solid and stranded cores.

LOAD BALANCING

If Load Balancing is required, we suggest of the BG SyncEV CT clamp, EVA120CT1. 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.

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.

• 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.

Network Setup / Commissioning Stage (1 of 2)

INSTALLER APP – Download the ‘BG EV Charging’ app here:Apple Version or Google / Android Version. Also available from the Installer Portal on the syncev.co.uk website, or using the QR codes opposite.

Upon powering the charger, the status indicator light will show Yellow. This indicates that the charger is ready for network setup but is not yet connected to the internet.
For Wi-Fi connection we recommend that the router is set to only 2.4GHz band to reduce the risk of possible conflicts. Once setup the router can be restored to both 2.4GHz & 5GHz bands.

1. Wifi SSID (network Name) – Drop down to scan for available networks and password
2. Lan DHCP – Enable for Lan/ethernet connections
3. Adjustable Max output current – 6-32A configurable
4. Enable for Dynamic load management, when using an external CT Clamp.
Set to CT sampling method and enter maximum current rating of the supply circuit
5. APP – smart charging with app control
RFID – RFID enabled chargers only
Plug And Charge – Non Smart charging use
6. App Type – Home
