Inspection on receipt
The prerequisites of faultless, safe operation of this de-
vice are proper transport and proper storage, set-up and
assembly, as well as careful operation and maintenance.
If it can be assumed that risk-free operation is no longer
possible, the unit must be immediately put out of opera-
tion and secured against being put back into operation
again.
The packing and unpacking must be carried out with
the customary care without the use of force and only
using suitable tools. The devices should be visually che-
cked for flawless mechanical condition.
It can be assumed that risk-free operation is no longer
possible if the device, for example,
• has visible damage
• no longer works despite the mains power supply
being intact
• has been exposed to long-term adverse conditions
(e.g. storage outside the permissible climate limits wi-
thout being adapted to the room climate, condensa-
tion etc.) or rough handling during transportation (e.g.
fall from a height, even if there is no visible external
damage etc.)
• Please check the delivered items for completeness
before you start installing the device.
CAll screw-type terminals included in
delivery are attached to the device.

Product description
Intended use
The UMG 96RM-EL is provided for the measurement
and calculation of electrical parameters such as voltage,
current, power, energy, harmonics, etc. for building
installations, to distributors, circuit breakers and busbar
trunking systems.
The UMG 96RM-EL is suitable for installation in
permanent, weatherproof switchboards. Conducting
switchboards must be earthed. It can be mounted in any
position.
Measurement voltages and measurement currents must
originate from the same grid.
The measurement results can be displayed and can
be read and processed over the Ethernet interface.
The voltage measurement inputs are designed
for measuring in low voltage grids in which nominal
voltages up to 300V phase can occur in countercurrent
with ground and overvoltages of overvoltage category
III.
The UMG 96RM-EL current measurement inputs are
connected via external ../1A or ../5A current transformers.
Measurements in medium and high voltage systems
generally use current and voltage transformers.
The UMG 96RM-EL can be used in residential and
industrial areas.

UMG 96RM-EL
Measuring method
The UMG 96RM-EL measures uninterrupted and
calculates all root mean squares over a 10/12-period
interval (200ms). The UMG 96RM-EL measures the true
root mean square (TRMS) of the voltages and currents
applied to the measuring inputs.
Operating concept
There are several ways to program the UMG 96RM-EL
and retrieve measured values.
• Directly on the device using two buttons.
• Via the programming software of the GridVis.
These operating instructions only describe the operation
of the UMG 96RM-EL using the 2 buttons.
The programming software of the GridVis has its own
“online help”.
GridVis network analysis software
The UMG 96RM-EL can be programmed and read with
the GridVis network analysis software which is part of the
scope of delivery. For this a PC must be connected to
the UMG 96RM-EL via Ethernet.
Characteristics of GridVis
• Programming the UMG 96RM-EL
• Graphic representation of measured values

When connecting the voltage measurement, the following
must be observed:
• A suitable separator must be provided in order
to switch off the power to the UMG 96RM-EL.
• The separator must be placed near the UMG 96RM-
EL, marked for the user and easily accessible.
• Use a fuse protected, UL/IEC approved 10A circuit
breaker (type C) as an overcurrent protection device
and separator.
• The overcurrent protection device must have
a nominal value that is designed for the short circuit
current on the connection point.
• Measurement voltages and measurement currents
must originate from the same grid
cAttention!
Voltages that exceed the permitted
ratedmains voltages must be connected
via voltage transformers.
cAttention!
The UMG 96RM-EL is not suitable for
the measurement of DC voltages.
