THE ENERGY METER

The energy meter needs to be configured on mains voltage, I will describe the procedure now, even though it was performed later after the safety inspection. The configuration was carried out as follows:
  1. The language was set to German.
  2. Network settings were adjusted, including assigning a static IP address and setting the subnet mask.
  3. The network type was set to: 3PH-4W-3CT, indicating a 3-phase network with four conductors and three current transformers.
  4. The current transformers were configured, specifying a ratio of 50 A primary current to 5 A secondary current.
  5. Finally, the configuration was verified and approved. The meter has a "0100" pin for saving changes.

The current transformers are mounted on a DIN rail inside of the controll cabinet. For that purpose we printed holders with 3D printers as shown in picture 2 and 3.
