UMG 604
Current measurement connection
options
The UMG604 recognises two connection
options for the current measurement.
Connection option 0
• Measurement via 3 current transformers
in three-phase-4-conductor systems.
• Measurement via 2 current transformers
in systems with the same load.
• Measurement in one-phase-3-conductor
systems.
Connection option 1
• Measurement via 2 current transformers
(Aron circuit) in three-phase 3-conductor
systems.
Address Connection option
110 0 = Three current transformers.
(Default factory setting)
1 = Two current transformers
(Aron circuit)
Fig. 49.1 Section of the parameter list for the
current transformer connection options.
For the inputs L4 and I4 are no con-
nection schemes required.
