5 Installation
5.1 First time charging of HarvyLR
Prerequisite: HarvyLR is set up on a LoRaWAN server (e.g. deZem IoT platform, i.e. deZem.io).
1.
For initial charging, we recommend connecting the HarvyLR to the computer via the optional USB adapter cable.
As soon as values are transmitted from the sensor to the LoRaWAN server, the HarvyLR is sufficiently charged.
The charging time is max. 6 min. when using the USB adapter cable.
2.
Disconnect the HarvyLR from the computer and remove the USB adapter cable.
Alternatively, the sensor can also be connected directly without charging beforehand, as described in the next sec-
tion. In this case, approx. 2 mAh are required for charging. Depending on the primary current, it may take a different
amount of time until the HarvyLR transmits values for the first time.
5.2 Connecting the sensor
1.
Connect the HarvyLR to the appropriate deZem clamp-on current transformer for an RMS current measurement
or to the adapter cable (for 4–20 mA signals). The sensor housing can be operated freely suspended or fixed
with cable ties.
