UMG 511
Apply the measurement voltage
• Voltage measurements in networks with nomi-
nal voltages above 500VAC against earth must
be connected using voltage converters.
• After connection of the measurement volta-
ges, the measurement values displayed by
the UMG511 for the voltages L-N and L-L
must match those at the voltage measurement
input.
• If a voltage converter factor is programmed,
this must considered in the comparison.
Initialization
Applying the supply voltage
• The level of supply voltage for the UMG511
can be taken from the label.
• After applying the supply voltage, a startup
screen appears on the display. Around 15
seconds later, the UMG511 changes to the
first measurement value display.
• If no display appears, you must check whe-
ther the supply voltage is within the nominal
voltage range.
Warning!
Supply voltages that do not corre-
spond with the details on the type
label can lead to malfunctions and
damage to the device.
c
Warning!
The UMG511 is only suitable for
measurement in networks in which
overvoltages of the overvoltage ca-
tegory 600V CATIII occur.
c
Warning!
The UMG511 is not suitable for
measuring DC voltages.

Prior to commissioning potential
production dependant contents of
the energy counter, min/max values
and records have to be deleted.
