Mounting notes

• All charging stations (or the storage means for the vehicle connector in tethered lead models) should be mounted at least 800mm above ground level. The lowest point of the vehicle connector when stored shall be at a height between 0.5m and 1.5m above ground level.
• The sides of the unit are not vertical and should not be used to find the level. The template has flat sides suitable for placing a level against it before drilling. When screwing the unit to the wall, use the top face of the unit to place a level against it. The unit must be mounted vertically as per illustrations. Horizontal installation is not allowed.
• Mounting holes must only be drilled in the 5 locations specified. It is the installer’s responsibility to ensure proper sealing of any drilled holes, including the installation of provided sealing plugs. See the arrows showing the 5 drilling locations.
• Galvanised steel and bare aluminium mounting surfaces must not be bolted directly to the brass mounting inserts on the back of the charger. Galvanic corrosion will occur between these dissimilar metals. Nylon or other non-metallic insulating washers are recommended.

Fasteners
Locate the packet labelled INSTALLATION MANUAL & FASTENERS containing the following:

Opening the unit
Remove the fasteners securing the front cover.
The cover has a tether to decrease risk of wire strain. This tether can be looped into the recess in the top right corner of the enclosure to keep the cover out of the way during installation.

Mounting the unit

• 5 x 5mm holes must be drilled in the unit for the mounting screws.
• Place the unit on a soft surface to prevent marking the unit while drilling the holes.
• Drilling too deep into the unit may cause the chuck of the drill to damage wires. Remove any plastic swarf from the unit as it could prevent water-tight installation of the sealing plugs and the front cover.
• The mounting surface must be flat to ensure that the unit is not twisted as it is fixed against the chosen wall.
• A cardboard drilling template is provided to allow easy marking out of the 5 mounting holes.
• For timber framed walls, 3mm pilot holes are recommended.
• For concrete walls, a 7mm masonry bit is required to allow the insertion of the supplied wall plugs.
• The location of the optional rear entry hole (M25 or M32) is also provided, along with the optional M12 hole location. M12 and M32 holes need to be drilled by the installer if required.
• Galvanised steel and bare aluminium mounting surfaces must not be bolted directly to the brass mounting inserts on the back of the charger. Galvanic corrosion will occur between these dissimilar metals. Nylon or other non-metallic insulating washers are recommended.

Timber framed wall mounting example

Solid wall mounting example

• The diagram below shows a cross-section of one of the five mounting holes in a solid wall such as concrete.
• For timber framed walls, the screws should enter solid structural framing inside of the wall. If this is not possible, proper anchoring hardware, suitable for the wall material and thickness, should be used.
• For concrete or other solid walls, use the supplied wall plugs. The recommended hole depth is 40mm with a 7mm masonry bit.
• For all types of installation ensure that the washers are installed on the screws and that the sealing plugs are installed after the screws are firmly tightened.

Wiring connection

• Always ensure that the main supply is isolated before beginning work on the charging station installation.
• The installer must ensure that the charging station is correctly earthed.
• The E & X Series are ‘mode 3’ charging stations. Due to their high current consumption, they must be connected to a dedicated feed from the main distribution board.
• The E & X Series of charging stations are not designed to charge vehicles that require ventilation systems during charging.
• A charging station is not to be powered on while the front cover is open

Single phase wiring example

Three-phase wiring example

Extra care is required with 3-phase wiring to ensure that the input wires do not interfere with the front cover or charging socket when the unit is closed. Excess wire may cause interference and prevent the unit from being properly closed

Upstream protection

• The following recommendations are provided as a guide. However, upstream protection should be installed per local regulations.
• Residual current protection and a suitably rated means of overcurrent protection should always be installed upstream of the charge point at the distribution board. This could be an MCB installed alongside an RCD or an RCBO.
• The maximum current draw of the product is determined by the DIP switch setting shown in page 23 of the installation manual.
• The tables below are advisory and based on the common availability of protection devices.

Short Circuit Protection: Circuit breaker
Single-phase

• For ≤ 16A: 1 x 20A, 1P, Energy Limiting Class 3, type C
• For 16A to 24A: 1 x 25A, 1P, Energy Limiting Class 3, type C
• For ≥ 24A: 1 x 32A, 2P, Energy Limiting Class 3, type C

Three-phase

• For ≤ 16A: 1 x 20A, 3P, Energy Limiting Classes 3, type C
• For 16A to 24A: 1 x 25A, 3P, Energy Limiting Classes 3, type C
• For ≥ 24A: 1 x 32A, 3P, Energy Limiting Classes 3, type C

Notes

• The MCB or RCBO should not be installed side by side with other high-load circuit protective devices to prevent thermal degradation when considering the grouping factor of devices.
• The maximum rated short-circuit capacity (Icn) is 6000 A.
• The circuit breaker must comply with one of the following standards: IEC 60898-1, IEC 60947-2, or IEC 61009-1.

Residual Current Protection: RCD
Single-phase

• For ≤ 16A: 1 x ≥ 20A, 2P, Rated Residual Current 30mA, type A or B
• For 16A to 24A: 1 x ≥ 25A, 2P, Rated Residual Current 30mA, type A or B
• For ≥ 24A: 1 x ≥ 32A, 2P, Rated Residual Current 30mA, type A or B

Three-phase

• For ≤ 16A: 1 x ≥ 20A, 4P, Rated Residual Current 30mA, type A or B
• For 16A to 24A: 1 x ≥ 25A, 4P, Rated Residual Current 30mA, type A or B
• For ≥ 24A: 1 x ≥ 32A, 4P, Rated Residual Current 30mA, type A or B

Notes

• The RCD must comply with one of the following standards: IEC 61008-1, IEC61009-1, IEC 60947-2, or IEC 62423
• The RCBO can be used instead of RCD and Circuit breaker. It must meet all RCD and Circuit breaker requirements as shown above.
• To avoid the requirement for more expensive type B RCDs, all E & X Series charge points have a 6mA DC detection device (Residual Current Monitor) built in. This is to prevent the blinding of type A RCDs from potential DC leakage currents. In the event of detecting a DC leakage current, the charge point will immediately stop the charging session and transition into a fault state, requiring a reboot to clear the state.

Power sensor terminal block

This terminal block is reserved for the installation of the Evnex Power Sensor. Refer to the Power Sensor Installation Manual.

Earthing the unit

For the minimum cross-sectional area of the protective conductor please refer to Table B1 of the current version of ASNZS3000.

Setting the maximum charge current
All E & X Series charging stations are set to 32A charge current as default. This maximum charge current is set via DIP switches on the PCB.
Depending on the capacity of your upstream supply, the maximum charging current can be set lower than 32A via the DIP switches during installation.

The DIP switches set the maximum allowable current that the charging station will draw.

Closing the unit

Checklist
Follow the checklist below before reinstalling the front cover:

1. Ensure all 5 mounting screws are installed with their sealing plugs and the unit is fixed securely against the wall.
2. Install M25 blanking plugs wherever there are unused 25mm holes. Ensure there are no other water ingress paths.
3. Check that the enclosure seal is properly pushed into the groove all the way around and that nothing is preventing the cover from closing or sealing properly.
4. Ensure that the input wires from the main supply are arranged in the enclosure with minimal excess length – too much extra wire can interfere with the front cover or charging socket and prevent the cover from closing or sealing properly.
5. Install the cover, tightening the ten cover fasteners to 2.5 N-m using a T20 Torx security bit.

Installing the front cover

Operation

Status display

Initialisation
When first connected, or when rebooting, the blue (NETWORK) light will begin to flash slowly. This indicates that the unit is attempting to connect to the cellular network. When the NETWORK light flashes quickly (10 per second), this indicates that the unit has connected to the cellular network, and is attempting to establish a connection with an OCPP server. When the NETWORK light begins to fade in and out slowly, the charging station has successfully established a connection with the server.

Charging process

Cables on non-tethered units are locked during charging. Excessive force must not be applied to remove the charge cable. If the cable is unexpectedly locked
The product is not to be operated when there is debris in the charging connector.

• For non-tethered models, connect the type 2 end of the cable to the charging station, and the other end (depending on the make and model of your vehicle) to the charging socket of your vehicle.
• For tethered models, simply connect the attached cable to your vehicle’s charging socket.
• Under normal circumstances, your vehicle should request a charge immediately.
• During the charge, the CHARGE light on the unit will glow green.

After charging, the tethered cable should be stored safely by wrapping it around the unit. Non-tethered cables may be removed or wrapped around unit.
