Janitza UMG 104 / UMG 604 / UMG 604-PRO (Utility Meter)
Cable connection via RS485:
1. Connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector
Solar-Log 50
Utility meter terminal strip
Terminal
PIN
►
1
1 or 5
22
►
4
4 or 6
23
2. Insert the terminal block connector into the Solar-Log™ RS485 socket.
•
The RS485 bus must be terminated.
Install a 120 Ohm, 0.25 W resistor between pin 22 and 23 of the Utility Meter to terminate.
•
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 / UMG 604 / UMG 604-PRO configuration
procedure.
Note
The parameter settings need to be adjusted before device detection.
If the parameters differ, the Utility Meter will not be detected by the Solar-Log™.
•
Perform an inverter detection
See the installation manual, Chapter „Performing inverter detections.“
•
Configure the Utility-Meter under
Configuration | Devices | Configuration
, select the corresponding
Opera-
ting mode
and click on
Save
.
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.
Note
When replacing the polarity, the cable must not be energized, since the converter can be de-
stroyed otherwise.
