UMG 508
Voltage Measurement Inputs
The UMG508 has 4 voltage measurement in-
puts (V1, V2, V3, V4).
Measurement category
The voltage measurement inputs are suitable for
measurements in networks in which overvolta-
ges in the measurement category 600V CATIII
can occur.
Frequency
The UMG508 requires the rated frequency for
measuring and calculating measurement values.
The UMG508 is suitable for measurements in
networks with a rated frequency in the range of
40Hz to 70Hz.
Illu. Connection example for voltage measure-
ment.
A connection diagram does not have
to be configured for the measurement
inputs V4 and I4.
