Hypervolt ALM/CT – Setup Guide


The Hypervolt ALM has been designed with ease of installation in mind. Its lightning-fast reaction time to overload currents coupled with the fact that Hypervolt records the power and energy from the CT means you will improve on the safety of your installation while gaining insights into the energy usage of the property.

How it works

The Hypervolt works using a wired CT sensor which the installer must clip over the main incoming power feed into the property. The Hypervolt CT is bidirectional meaning that the Hypervolt is able to differentiate between export and import powers respectively.

Your property will have a maximum allowed total power consumption that can be configured inside your Hypervolt. Once installed and configured, the charger monitors this consumption in real-time. In the event that charging would cause you to exceed the pre-set limit, we will then reduce the EV charging rate in order to protect your electrical wiring and avoid blowing the fuse in your meter whilst continuing to charge your vehicle.

Wiring and setting up

CAUTION: make sure the Hypervolt is switched off and isolated from the mains before proceeding.

Connect the CT to the internal 2-pole signal connector provided inside the Hypervolt.

You must ensure the polarity of the CT is correct. The CT should be wired with the white lead into the left-hand side terminal of the connector. The arrow on the CT should point in the direction of the load.

If you need to put the CT on the Neutral instead of the Live, the arrow on the CT should now point opposite the load.

Use the same Cat5 Cable for ALM/CT and RJ45 (ethernet) port inside the unit:

Use Orange/Orange-White and Green/Green-White for the RJ45 that goes into Ethernet and then use either one of the left pairs for the CT core.

Locate the rotary switch. It is situated adjacent to the CT connector you have plugged the CT into.

Use the following table to select the switch position which matches your requirements for the installation. Note: Each installation is different; hence the settings will differ from site to site.

*** use this setting only to indicate that a CT is installed but when ALM is not required. When this setting is selected, the Hypervolt will know a CT is connected and record the CT power and energy measurements for the CT.
