13.4 Phase sequence
Verify the direction of the rotating field voltage in
the measured value display of the device.
·Normally a “right” rotation field exists.
UL1-UL2-UL3 = right rotation field
UL1-UL3-UL2 = left rotation field

13.5 Frequency
The device requires the rated or power frequency
to measure and calculate measured values,
which can either be specified by the user or
automatically determined by the device.
NOTE
The UMG 96-PA
MID
only supports automatic
frequency calculation (45 -65 Hz)!
·To determine power frequency, a voltage
greater than 20 V
eff
(4-conductor measurement)
or a voltage L1-L2 greater than 34 V
eff
(3-conductor measurement) must be present at
voltage measurement input V1.
·The power frequency must be within the range
of 45 to 65 Hz.
·If the applied voltage is not sufficiently high, the
device will be unable to determine the power
frequency and thus will also not be able to
conduct a measurement.
More information can be found in chap. „12.3.1
Rated frequency“ on page 35
