UMG 512
Connecting the measured voltage
• Measurement of voltages in networks with over
500VAC to earth must be connected via voltage
transformers.
• After connecting the measured voltages,
the measured values displayed by the UMG 512
for the L-N and L-L voltages must correspond
to those at the voltage measurement input.
• If a voltage transformer factor is programmed,
it must be taken into consideration for
the comparison.
Commissioning the unit
Connecting the supply voltage
• The supply voltage level for the UMG 512
is specified on the rating plate.
• After connecting the supply voltage, a display
appears. Approximately 15 seconds later, the UMG
512 switches to the first measured value display.
• If no display appears, check whether the power
supply voltage is within the rated voltage range.
Please note!
If the supply voltage does not correspond
to the voltage indicated on the rating
plate, this may lead to malfunctions
and severe damage to the device.
c
Please note!
The UMG 512 is only suitable for
use in networks where overvoltages
of overvoltage category 600V CATIII can
occur.
c
Please note!
The UMG 512 is not suitable for
measuring DC voltages.

Prior to commissioning potential pro-
duction dependant contents of the ener-
gy counter, min/max values and records
have to be deleted.
