Product description
Intended use
The UMG 96RM-M 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-M is suitable for installation in
permanent, weatherproof switchboards. Conducting
switchboards must be earthed.
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 M-Bus 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-M 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-M can be used in residential and
industrial areas.

UMG 96RM-M
Measuring method
The UMG 96RM-M measures uninterrupted and
calculates all root mean squares over a 10/12-period
interval. The UMG 96RM-M measures the true root mean
square (TRMS) of the voltages and currents applied to
the measuring inputs.
Operating concept
The UMG 96RM-M can be programmed directly on the
device via the 2 buttons. In addition, measurement values can be called up via the M-Bus interface - e.g. with
the GridVis read-out software.
The programming software of the GridVis has its own
“online help”.
10
UMG 96RM-M
Netzanalysesoftware GridVis
The UMG 96RM-M 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 via a
serial interface (RS232 / USB) for example via an M-Bus
Master (level converter) to the M-Bus interface of the
UMG 96RM-M.
The configuration of the UMG96RM-M is implemented
exclusively via the two buttons on the device - the GridVis software does not support this function!
It is not possible to read out M-Bus devices provided by
other manufacturers using the GridVis software!

UMG 96RM-M
Current measurement
The UMG 96RM-M is designed for connecting current transformers with secondary currents of ../1A and
../5A. The factory set current transformer ratio is 5/5 A
and may need to be adapted to the current transformers.
It is not possible to perform a direct measurement without a current transformer with the UMG 96RM-M.
Only AC currents (and not DC currents) can be measured.

Current transformer terminals!
The secondary terminals of the current
transformer must be short-circuited to this
before the power supply lines to the UMG
96RM-M are disconnected!
If a test switch which automatically shortcircuits the current transformer secondary
leads is available, it is sufficient to put this
into the “test” position provided the shortcircuiters have been checked beforehand.
c
Open current transformer!
High voltage peaks that are dangerous to
touch can occur on current transformers
that are operated in an open state at
the secondary terminals.
In “open-safe current transformers”, the
winding insulation is measured so that the
current transformers can operate in an open
state. However, these current transformers
are also dangerous to touch if they are
operated in an open state.

M-Bus interface
The M-Bus interface is designed with the UMG 96RM-M
as a 2-pole plug contact and communicates via the MBus protocol.
The UMG 96RM-M loads the M-Bus with an M-Bus device load of 1.5 mA.

M-Bus interface,

) via twin ferrules
Cable connections
Twisted screened cable should be used for connections
via the M-Bus interface.
• Cable paths should be designed to be as short as
possible.
• Maintain as much distance as possible to power cables and to consumers (e.g. electrical motors, neon
tubes, transformers).
• In order to prevent cross currents in the bus, there
should be no ground coupling, or a maximum of one
instance of ground coupling.
• Gather the cables mechanically above the earthing
clamp in order to avoid damage due to cable movements.
• Use suitable cable glands to feed the cables into the
cabinet - for example armoured conduit couplings.
29
UMG 96RM-M
Cable type
The cable used must be suitable for an ambient
temperature of at least 80 °C.
Use 2-core, twisted, screened cable wherever possible
for optimum data transmission.
Recommended cable types:
Unitronic LIYCY 4x0.75

Bus structure
• All devices are connected in a star, line or tree structure, whereby each device has its own address within
the bus (see also Parameter programming).
• A subdivision of the network structure into individual
segments is implemented via repeaters (line amplifiers).
• Up to 250 subscribers can be connected together in
a single segment. However, the characteristics of the
Master device are the defining factors here.
• If the master is replaced, the bus is out of service.
• Devices can be replaced without the bus being unstable.
Star structure
• Each measurement device is linked directly to the
M-Bus Master. Faults in the bus system are localised
faster by switching the individual devices on and off.
Line structure
• The connection of the measurement devices is sequential, in a line. With this possible faults in the bus
system may arise due to the voltage drop. Faults
within the system are harder to localise in this cheaper
structure.
