UMG 96RM
Commissioning
Applying the supply voltage
• The level of supply voltage for the UMG 96RM can be
found on the nameplate.
• After applying the supply voltage, the UMG 96RM
switches to the first measured value display.
• If no display appears, the supply voltage must
be checked to determine whether it is in the rated
voltage range.
Applying the measured voltage
• Voltage measurements in networks with rated voltages
above 300V AC to ground must be connected to a
voltage transformer.
• After the measured voltages are connected, the
measured values for the L-N and L-L voltages
displayed by the UMG 96RM must match those at
the voltage measurement input.

Attention!
Supply voltages that do not correspond
to the nameplate information can lead
to device malfunction or destruction.
m
Attention!
The UMG 96RM is not suitable for the
measurement of DC voltages.
Applying the measured current
The UMG 96RM is designed for connecting ../1 A
and ../5 A current transformers.
Only AC currents and not DC currents can be measured
via the current measurement inputs.
Short circuit all current transformer outputs except for
one. Compare the currents displayed on the UMG 96RM
with the applied current.
The current displayed by the UMG 96RM must match
the input current, taking the current transformer ratio into
consideration.
In the short circuit current measurement inputs, the UMG
96RM must show approx. zero amperes.
The factory-set current transformer ratio is 5/5 A and may
need to be adapted to the current transformer used.

Attention!
Voltages and currents outside the permis-
sible metering range can result in personal
injury and damage to the device.
