Voltage Measurement Inputs
The EM-PQ2500 has 4 voltage measurement
inputs (V1, V2, V3, V4).
Overvoltage
The voltage measurement inputs are suitable for
measurements in networks in which overvolta-
ges in the overvoltage category 600V CATIII can
occur.
Frequency
The EM-PQ2500 requires the rated frequency
for measuring and calculating measurement va-
lues.
The EM-PQ2500 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.
