Product description
Proper use
The UMG 96RM is intended for the measurement and
calculation of electrical parameters such as voltage,
current, power, energy, harmonics etc. in building
installations, on distribution units, circuit breakers and
busbar trunking systems.
The UMG 96RM is suitable for integration into fixed and
weatherproof switch panels. Conductive switch panels
must be earthed. Can be installed in any attitude.
Measured voltage and measured current must derive
from the same network.
The measurement results can be displayed and can be
read out and further processed via the interfaces.
The voltage measurement inputs are designed for
measurements in low voltage networks, in which rated
voltages of up to 300V relative to earth and surges in
overvoltage category III can occur.
The current measurement inputs of the UMG 96RM are
connected via external ../1A or ../5A current transformers.
The measurement in medium and high voltage networks
is implemented in principle via current and voltage
transformers. The UMG 96RM can be employed both
domestically and in industry.

Measuring process
The UMG 96RM measures continuously and calculates all
effective values over a 9 period interval. The UMG 96RM
measures the real effective value (TRMS) of the voltage
and current connected to the measurement inputs.
Parameterising
You can parameterise the UMG via buttons 1 and 2 or
via the RS485 or USB interface.
You can only parameterise a small portion of the functions
directly on the device via the buttons. The list of functions
can be found in table 1 of the installation instructions for
the basic device.
All functions can be parameterised via the serial
interfaces and with the GridVis programming software.
Only the RS485 interface is available on
the basic device.
C
Additional components that are not
included in the scope of deliverables will
be required for parameterisation via the
RS485 interface.

LED status bar
The different statuses of the inputs and outputs are
displayed via the LED status bar on the rear of the device.
Digital inputs
The LED associated with the respective input illuminates
green if there is a signal of at least 1mA flowing through
the interface.
Digital outputs
The LED associated with the respective output
illuminates green if the output is active - independent of
whether there is a connection on the interface.
Profibus (only UMG 96RM-P variant)
The LED associated with the Profibus provides
comprehensive information by means of a red or green
illumination and a flashing frequency, in accordance with
table 5.1.

Current transformer input I4
The 4th current transformer input is intended for
the connection of current transformers with secondary
currents of ../1A and ../5A. The factory default for
the current transformer ratio is 5/5A and must be adapted
to the current transformer employed if necessary.
Direct measurement without a current transformer is not
possible with the UMG 96RM-P/-CBM.
Only AC currents can be measured - DC currents cannot.
In doing so, with a voltage only an apparent current
measurement is possible due to the multiplier being
missing. Power measurements with the help of this
input are thus not possible.
cImportant!
The current measurement inputs are
dangerous to touch.
mImportant!
The UMG 96RM is not suitable for
measuring DC voltages.
cEarthing of current transformers!
If a connection is provided for the earthing
of secondary windings then this must be
connected to the earth.

CIt is not necessary to configure a connec-
tion schematic for the I4 measurement
input.

17
UMG 96RM-P/-CBM
cCurrent transformer connections!
The secondary connection of the current
transformer must be short-circuited on this
before the current feed to the UMG 96RM
is disconnected!
If a test switch, which automatically short-
circuits the secondary wires of the current
transformer, is available then it is sufficient
to set this to the "Test" position insofar
as the short-circuiting device has been
checked beforehand.
cOpen-circuit current transformers!
High voltage spikes that are dangerous to
touch can occur on current transformers
that are driven with open-circuit secondary
windings! With "safe open-circuit current
transformers" the winding insulation is
rated such that the current transformer
can be driven open. However, even these
current transformers are dangerous to
touch when they are driven open-circuit.
mMounting, installation, operation, configu-
ration and commissioning of the device
should be carried out in accordance with
the enclosed instructions "UMG 96RM
basic device".
Follow all safety regulations and warning
information.
mDirect measurement
Direct measurement of the nominal
current without a current transformer is
not possible with the UMG 96RM

UMG 96RM-P/-CBM
USB interface
The Universal Serial Bus (USB) enables a rapid and
uncomplicated connection between the device and
a computer. After the installation of the USB driver
the device data can be read out via the GridVis software
and firmware updates can be installed.
The USB2.0 connection cable with A/B connectors
included in the scope of deliverables is required for
the USB connection of the device to the USB interface
of the computer.
