UMG 605US
Putting into Service
Applying the power supply voltage
The power supply voltage level for the
UMG605US is given on the rating plate.
Supply voltages which do not correspond to
those given on the rating plate can result in
malfunctions and destruction of the device.
After applying the power supply voltage the
text “Start up” appears in the display. Around
two seconds later the UMG605US switches
to the first measured value display.
If no display appears, check whether the
power supply voltage is within the rated
voltage range.
Frequency measurement
For automatic ascertainment (wide range) of
the frequency, an L1-N voltage larger than
10Veff must be applied to the voltage mea-
surement input V1.
Only detected frequencies within the range
45 Hz to 65 Hz are used for measurement at
the current and voltage measurement inputs.
Power supply voltage
(see rating plate)
Prior to commissioning potential pro-
duction dependant contents of the
energy counter, min/max values and
records have to be deleted.
