This installation covers the Phoenix Contact EEM-MB371 Powermeter specifically.
Before installing the power meter, it is a good idea to install the gateway.
The power meter is connected via ethernet to the same network that the gateway is in (for example, via a switch).
For information on connecting current transformers and the voltage measurement, please check the EEM-B370/371 manuals from Phoenix contact.
Once installed according to Phoenix Contact and the image below you can setup the powermeter.
