Configuring the Utility Meter from the display
Setting MODBUS Address (PRG 200 = 1)
Setting Baud rate RS485 (PRG 202 = 2)
Setting Mode (PRG 203 = 0)
Setting Current converter primary (PRG 000)
Setting Current converter secondary (PRG 001)
Setting Voltage converter primary (PRG 002)
Setting Voltage converter secondary (PRG 003)
Refer to the accompanying manual of the device for the UMG 104 configuration procedure.
Note!
•
Perform an inverter detection
See the installation manual, Chapter "Performing inverter detections."
•
Configure the Utility-Meter under
ing Operating mode
Check
•
Does the Utility Meter display a positive value for inverters feeding power, the current output
(kW)?
If this is not the case, the current measurements are incorrectly connected.
If necessary, switch the polarity of measuring inputs.

The measurement voltage must in effect be at least 10V or an exact measurement is not
possible.
