64A (3 phase supply)| 1 x 22 kW| 2 x 22kW
32A (3 phase supply)| 1 x 22 kW| 2 x 11kW
32A (3 phase supply)| 1 x 7kW| 2 x 7kW
32A (1 phase supply L1)| 1 x 7kW| 2 x 3.S kW

Please Note:
The TwentyTwo Dual is designed to handle a total output capacity of 44kW at 64A on an incoming 3 phase supply. The denoted output settings above are achieved and optimised by limiting the incoming power supply, and then configuring the charge point max output current via the password protected touch screen LCD menu. For all configurations lower than 2 x 22kW the output current must be reduced to 32A from 64A to ensure correct connector power balancing is implemented. *Can be limited to 2x 7kW via dedicated FW update if required.

For more detailed specifications please see the VCHRGD TwentyTwo Dual Datasheet. You can also access all documents pertaining to EVSCP Compliance as an approved installer, either by request, through www.VCHRGD.com or they will have been sent to you on purchase of the VCHRGD TwentyTwo Dual. End users can access the Statement of Compliance and Technical File via the VCHRGD Home app main menu.

Packaging

VCHRGD TwentyTwo Dual Packaging is 100% recyclable. After your installation is complete, please retain all relevant printed collateral and documentation and recycle the remaining packaging responsibility, and in accordance with your local recycling guidelines and practices.

Install kit:

The following are provided with every purchase:

• 1x Drilling template
• 5x Insulated ferrules
• 4x 8mm ⌀ expansion wall plugs 45 to 60mm
• 4x 5mm ⌀ 45mm screws
• 1x Security Key

1. This electrical device should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by the manufacturer for any consequences arising out of the use of this device. A qualified person is one who has skills and knowledge related to the construction, installation and operation of electrical device and who has received safety training to recognise and avoid the hazards involved.
2. All applicable local, regional, and national regulations must be respected when installing, repairing, and maintaining this device.

An additional small flat head screwdriver will be required for loosening and tightening the incoming power line terminals. The charger is secured to the mounting bracket using 2x Torx+ Security Screws, the drill bit for which is provided in the fixings pack with every TwentyTwo Dual purchase.

Protection

Safety precautions for installation: The charger has integral RCD protection rated at (AC 30mA & DC 6mA). 6mA DC fault current disconnection device was verified to IEC 62955 standard by TUV SUD. It is necessary to install a 40A or 80A RCBO and RCD Type A in line before the charger, for multi-level safety protection RCD Type A should be tested in accordance with BS 7671 Since 27TH SEPTEMBER 2022, THE NEW 18TH EDITION AMENDMENT 2 OF THE WIRING REGULATIONS CAME INTO EFFECT. WITH THESE NEW REGULATIONS, ALL NEW ELECTRICAL CIRCUITS MUST HAVE SURGE PROTECTION DEVICES (SPDS) FITTED. SOME INSTALLERS MAY CHOOSE TO ENTER INTO AN OPT OUT AGREEMENT WITH THE CUSTOMER, HOWEVER THIS IS THE SOLE RESPONSIBILITY OF THE INSTALLER TO AGREE WITH THE END USER PRIOR TO INSTALLATION.

Bracket Mounting

1. Identify mounting point at a height of 0.5m to 1.5m above the ground, hold bracket flush to surface, and level. Mark wall at fixing points highlighted below.
2. Drill holes accordingly M5*45mm screws provided with unit using a torque setting of 1Nm fix back plate.
3. Slot the charging case downwards into the back plate, ensuring a secure fit and tighten with Torx+ Screws provided until secure. NOTE: As the power line is fed into the charger from the bottom of the case, please leave sufficient clearance from the mounting point to the desired termination point for the cable run. The hinged front cover allows for easy access to the internal wiring terminals, allowing for simple termination post bracket mounting.

Wiring:

Incoming Power Line
Case internals are labelled accordingly

• L1 – Live Phase 1
• L1 – Live Phase 1
• L1 – Live Phase 1
• N – Neutral
• PE – Protective Earth

Energy Management Line
From left to right the following apply. With the top input being the positive input and bottom input being the corresponding negative

Top Row
Solar +, CTA+, CTB+, CTC+, RS485B.

Bottom Row
Solar -, CTA -, CTB -, CTC – RS485A.

NOTE
If extending the CT clamp for dynamic load management and solar functions, please use a twisted pair connection such as CAT5E or a suitable EV cable. Match the polarity of the CT accordingly, ensuring that the coloured and white connections of the twisted pair correspond to the positive and negative inputs of the charge point side connections. A reversal of polarity will lead to inaccurate or inverse current readings.

Dynamic Load Management
Load balancing requires the use of the specified CTs (ensure CTs are specified as required at time of order). 3 phase load balancing requires 3 x CTs per charger.

Note CT clamps are directionally sensitive, please ensure polarity matches per previous section.

The maximum site/property current can be set at the installation stage via the LCD configuration menu in the DYNAMIC LOAD section. On commencing a charging session, the charger will commence at 6A and increase until the monitored current reaches its maximum set value less 2A. Should the monitored mains current change during a charging session the charger will adjust (increase or decrease) its own current to ensure the household current remains at 2A less than the maximum threshold.

Example Dynamic load threshold set to 60A >> Monitored Load = 40A Charging commences at 6A and incrementally increases to 18A (total load 58A) Monitored load at site decreases to 50A due to decreased mains utilisation Outlet current increases to 26A (total load 58A) maintaining threshold buffer of 2A.

Metering Interface
The charger has two-meter interfaces (MID meters) with RS485 communication and baud rate of 9600. The designated value of connector A is 1 and the designated value of connector B is 2. To check the digit select “NONE” The first MID meter communication is used for internal power measurement. The second MID meter is used for external current monitoring and can be used for dynamic load balancing in place of the CT connections.

Connect

The VCHRGD TwentyTwo Dual is designed to be a flexible and configurable enabler for multiple back-end providers and management services to connect with via OCPP 1.6J. Using the 4.3 inch LCD touch screen the installer can commission and connect the charger to the desired backend service via OCPP URL, connect to WiFi or 4G services, configure dynamic load management services and much more. This section offers a complete guide to commissioning, connecting and configuring your new VCHRGD TwentyTwo Dual, the final step on the road to world class fast charging.
