INTRODUCTION

This guide is intended for use by competent electrical installers to explain basic requirements and options to be considered when installed a SYNC EV BG 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 EVS7 charger and should not be used with other EV chargers.

IDENTIFICATION LABEL
……………………………………………………….

SAFETY INFORMATION

Warning: The supplied 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, eg: BS7671:2018 amendment 2.
The single phase SYNC EV BG BG 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 SYNC EV BG BG 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 IP65 Electric Vehicle charger enclosure when mounted next to the existing consumer unit as it has a 2 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 Charging point 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.

EARTHING REQUIREMENTS
The supplied charger features an on-board safety monitoring system to detect low or high voltage supplies and potential earth-neutral faults, this in accordance with  egulation 722.411.4.1 (iv) of BS7671 2018 (Compliant on single phase supplies only). If such a condition is encountered the charge cycle isended or prevented and the 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 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,  arning labels should be visible and close to the unconnected SWA protective earth eg inside the charger. The earth connection shall be made from the electrode to the charge
via copper conductor earth wire of an appropriate CSA for theinstallation. The earth wire shall be installed in conduit where there
is a risk of mechanical damage or UV exposure. Additional note:
SYNC EV recommend Earth electrode impedance to be <100 ohms.

ISOLATION AND SWITCHING FOR SAFETY AND MAINTENANCE

To ensure that the charger can be “turned off” to enhance security and enable maintenance activities, a double pole isolator (or 2 pole 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 at a height of 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 regulations

INSTALLATION

The 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.
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 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.
SYNC EV BG 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
If Load Balancing is required, we suggest use of EVA120CT1 as a compatible CT clamp. This should be fitted around the incoming power to the main fuse and the correct max load (A) to be entered during set up and installation steps.
All of the cables that are to be connected into the supply connector should have their insulation stripped back 18-20mm. Connectors supplied are suitable for cables of 4-6mm² and suitable for solid and stranded cores.

FINAL ELECTRICAL TESTING

To meet the BS7671 (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 SYNC EV BG unit 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 timescales (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 Charger.

An electrical installation certificate must be completed. Ensure Electrical testing is done before charger commissioning and network set up is performed

WI-FI CONNECTION GUIDE

This is the installers responsibility and must be done to complete the installation.
We recommend the WiFi router is set to only 2.4GHz band during set up to reduce the risk of possible issues during set up. Once set up the router can then be restored to both 2.4GHz and 5GHz bands.
Upon powering the Sync EV unit, the status indicator light will show Yellow. This indicates that the health of the charging unit is good but there is no connection to the Sync EV Network.
The BG EV Charging installer app can be downloaded via the installer portal on www.syncev.co.uk

1. Connect to the charger through the BG EV installer application. The app will scan for available Bluetooth devices and select the one matching the ChargerID Code on the charger identification label.
2. The charger will then request the password, The default password is also on the identification label. We recommend this is changed during set up and noted on the identification label.
3. Once this is entered the app will then show the full configuration page.
   Scan and select the required WifI SSD, and enter the correct password. This screen will also allow the configuration of charge mode and if Load balancing (Power distribution) is required.

For Charge Mode, the default is APP which requires a confirmation within the SYNC EV app to start charging, this can be changed to a Plug and Charge function which will charge without secondary confirmation.
For Load balancing, if a CT clamp is fitted this should be enabled and set to the correct home current limit. This should be the same or less than the main fuse rating. With this setting, the Charger will reduce its charging rate to limit the total home load to be under the limit. If the available current is under the minimum of 6 Amps the charger will pause the charging session.
When all the correct functions are entered, select Set to upload settings. The charger will beep to confirm.
After 15 seconds, the Yellow Indicator should turn Blue to confirm connection to network and app server. If the charger continues to show yellow, the charger should be power cycled and reconnected via the app to check correct settings.
GSM and RFID enabled charging points
