UMG 96RM-PN
Commissioning
Connecting the supply voltage
• The supply voltage level for the UMG 96RM-PN is
specified on the rating plate.
• After applying the supply voltage, the UMG 96RM
switches to the first measured value screen.
• If no display appears, check whether the power supply
voltage is within the rated voltage range.
Connecting the measured voltage
• Measurement of voltages in networks with over
300VAC to earth must be connected via voltage
transformers.
• After connecting the measured voltages, the measured
values displayed by the UMG 96RM-PN for the L-N
and L-L voltages must correspond to those at
the voltage measurement input.

Attention!
Voltages and currents that are outside
the permissible measurement range
can cause personal injury and lead to
the destruction of the device.
m
Attention!
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.
m
Attention!
The UMG 96RM is not suitable for
measuring DC voltages.
Applying the measuring-circuit voltage
The UMG 96RM-PN is designed for the connection of ..
/1A and .. /5A current transformers.
Only AC currents can be measured via the current
measurement inputs - DC currents cannot.
Short circuit all current transformer outputs except for
one. Compare the currents displayed by the UMG 96RM
with the applied current.
Bearing in mind the current transformer conversion
ratio, the current displayed by the UMG 96RM-PN must
correspond with the input current.
The UMG 96RM-PN must display approx. zero amperes
in the short circuited current measurement inputs.
The current transformer ratio is factory-set to 5/5A and
must be adapted to the current transformer used if
necessary.
