Instructions for use
Please read the operating manual at hand as well as all
other publications that must be drawn from for working
with this product (in particular for the installation, opera-
tion or maintenance).
Follow all safety regulations and warning information.
If you do not follow the information, it can result in bodily
injury and/or damage to the product.
Any unauthorized changes or use of this device, which
transcend the mechanical, electrical or otherwise stated
operating limitations, can result in bodily injury or/and
damage to the product.
Any of such unauthorized changes constitute „misuse“
and/or „negligence“ in terms of the warranty for the pro-
duct and therefore eliminates the warranty for covering
any potential damage resulting from this.
This device is to be operated and maintained exclusively
by specialized personnel.
cIf the device is not operated according to
the operating manual, protection is no lon-
ger ensured and danger can come from
the device.
mConductors made from single wires must
be fitted with wire-end ferrules.
mOnly pluggable screw terminals with
the same number of poles and the
same type of construction are permitted
to be connected together.
Specialized personnel are persons, that based on their
respective training and experience, are qualified to re-
cognize risks and prevent potential dangers that can be
caused by the operation or maintenance of the device.
Additional legal and safety regulations required for
the respective application are to be following during the
use of the device.

UMG 96RM-EL
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.
Concerning these operating instructions
These operating instructions are a part of the product.
• Read the operating instructions before using the de-
vice.
• Keep the operating instructions throughout the enti-
re service life of the product and have them readily
available for reference.
• Pass the operating instructions on to each subse-
quent owner or user of the product.

UMG 96RM-EL
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.

• Frequency range: 45-65 Hz
Device functions
• 3 voltage measurements, 300 V
• 3 current measurements
(via current transformer)
• Ethernet interface

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.

• Programming the UMG 96RM-EL
• Graphic representation of measured values
