3.2 Intended use

HarvyLR is used for wireless acquisition of AC and DC currents via LoRaWAN and it is self-powered, i.e. it does not

require an external power supply or battery. It is particularly suitable for the acquisition of RMS currents using the

deZem clamp-on current transformers as well as industrial 4–20 mA output signals. The intelligent event filter inte-

grated in the sensor provides metering t series (inrush currents, etc.) accurate to the second at a defined maximum

rate.

Any application other than described above, as well as modifications to the product, are considered improper use

and may impair the protective effect.
