Physical installation
When the sensors have been digitally configured it is time to physically activate and install
them. The OY1410 is dedicated to use together with BMeters’ IWM-PL3 or IWM-PL4 units.
First install and configure the IWM-PL3 or IWM-PL4 unit according to BMeters’ instruction.
It is important to configure it according to the table below:

Oy1410 is configured with the same setting. The table below shows the settings for different
