The charger is pre-configured in PEST Mode B, ensuring compliance with BS 7671:2018 Amendment 3, Regulation 722.411.4.1, Indent (iv).

How it works:

In this mode the charger will monitor the for deviation outside of the acceptable range (253V – 207V).

  • If the supply voltage goes outside this range, the charger automatically stops charging.
  • Charging will resume once the voltage returns to the acceptable range.

This configuration is suitable for the majority of installations.

Need a different configuration?

Setting the charger to PEST mode A is a way of telling the charger that O-PEN faults are being managed elsewhere. E.g. the installation is on TT, or the car and charger can only be inside when charging.
PEST mode A exists for when the other options are not suitable and is designed around compliance with regulation 722.411.4.1 indent (iii) BS7671 AMD 3.

This method removes the need to measure supply voltage to identify O-PEN faults, thus mitigating issues with variable supply voltages.

It uses a voltage reference in the ground and compares its voltage to that of the CPC of the installation. If the voltage between the two goes over 30V the charger disconnects from the car and will not offer again until the voltage drops back within range.

Reference Electrode:
A reference is a voltage reference only, it is NOT a fault return path and is a TT electrode cut down to 300mm and should achieve a resistance of <600Ω. This enables the reference to be stable when the ground dries out in the summer.

The reference should be connected to the “RefE” connection in the charger.

• Voltage Reference ONLY
• 300mm long
• Minimal risk of striking buried services
• <600Ω
• Solar PV Cable

If the charger needs to use Load Curtailment or Solar Mode features, an external CT (Current Transformer) must be installed. A CT is included in the box. This allows the charger to monitor the total electrical demand of the installation and the total export from any micro-generation system.

1. Position the CT:

The CT should be clipped onto the incoming live supply cable before any junctions. With the arrows facing the grid (see photo).

2. Connect the CT Clamp wires:

Use the provided jelly crimps to join the CT clamp wire to the Blue/Blue White pair of your data cable.

Blue & whiteWhite

3. Terminate the data cable:

Using an IDC punch-down tool, terminate the Blue/Blue White wires into the CT connector.

Note: other data cable colours may be used but must terminate into the BE, BE/WE connection inside the charger.
