Configuration
Voltage measurement connection
options
The UMG604 recognises two connection
options for the voltage measurement.
Connection option 0
Direct measurement of the voltage in •
3-phase 4-conductor systems.
Measurement via 3 voltage transformers •
in 3-phase 4-conductor systems.
Connection option 1
Direct measurement of the voltage in •
three-phase 3-conductor systems.
Measurement via 2 voltage transformers •
(Aron circuit) in three-phase 3-conductor
systems.
Address Connection option
111 0 = Three-phase 4-conductor
systems (default factory
setting)
1 = three-phase 3-conductor
systems
