RCD (Residual Current Device)
An RCD is a safety device used to ensure that the charger stops supplying electricity in the event that there is an electrical fault to earth. !
The Hypervolt has built-in 6mA DC protection but no built-in AC protection, it must therefore be connected to an individual “A” Type Double Pole RCD
or RCBO not exceeding 30mA; complying with IEC61008-1 /IEC61009-1 / IEC60947-2 / IEC62423.
CT (Current Transformer) often called Current Clamp or CT Clamp
The single CT clamp supplied must be fitted to measure the main load on the property and discover solar export.!
The CT clamp provided should go around the main incoming Live (Brown or Red) meter tail with the arrow pointing in the normal direction of current
flow (Please refer to page 10 for further installation instructions). It is equally important that the wires from the CT clamp go the correct way round
inside the Hypervolt unit, the White Wire should go in the LEFT and the Black Wire should go in the RIGHT of the green connection plug (8). If you
extend the wires remember to follow these connections through. Details of how to test the CT clamp are on page 15.!
The CT Clamp should be positioned where it will measure the total load on the property. If you wish to position it in a different location due to
practicality permission should be sort from Hypervolt first. Be aware that positioning other than at the origin of the supply will limit the functionality of
the Hypervolt.!
Note: The CT clamp wiring can be extended up to 40m using Cat5e cable or 80m using HyperConnect cable.
PEN Fault Protection
Hypervolt chargers have built-in PEN fault protection which means they can be connected to a PME (TN-C-S) incoming service which shares Neutral &
Earth in the same conductor. There is no requirement to install an additional earth rod. In the event that the Protective Earth and Neutral (PEN)
conductor becomes damaged/disconnected our PEN Fault system will isolate all conductors to protect the user from potential danger a PEN fault
presents.
Overheating Sensing
Hypervolt chargers have built-in temperature sensors; in the event where it recognises there is too much heat being generated it will reduce the current
being delivered to the EV, this will ensure the charger is not damaged as a result of overheating.
