injuries or damage to property can occur if they
are not handled properly:
• Before connecting connections, earth the
device at the ground wire connection if
present.
• Hazardous voltages may be present in all
switching parts that are connected to the
power supply.
3
• Hazardous voltages may also be present
in the device even after disconnecting the
supply voltage (capacitor storage).
• Do not operate equipment with current
transformer circuits while open.
• Do not exceed the threshold values specified
in the user manual and on the rating plate.
Also adhere to this when inspecting and
commissioning.
• Observe the safety and warning instructions in
the documents that belong to the device!

The tree structure combines the star and line structure:
• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus
segments are usually affected in the event of a fault.
• Connect M-Bus devices in star (1),
line (2) or tree structures (3).
• Each M-Bus device has its own address
within the bus structure.
• Divide (expand) bus structures into individual
bus segments with repeaters (line amplifiers).
• Up to 250 subscribers can be connected
together in a single bus segment (depending
on the M-Bus master).
• The bus structures ensure that the system
remains stable when M-Bus devices are
exchanged.
• The bus structure is out of operation during
a replacement of the M-Bus master.

The tree structure combines the star and line structure:
• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus
segments are usually affected in the event of a fault.
• Connect M-Bus devices in star (1),
line (2) or tree structures (3).
• Each M-Bus device has its own address
within the bus structure.
• Divide (expand) bus structures into individual
bus segments with repeaters (line amplifiers).
• Up to 250 subscribers can be connected
together in a single bus segment (depending
on the M-Bus master).
• The bus structures ensure that the system
remains stable when M-Bus devices are
exchanged.
• The bus structure is out of operation during
a replacement of the M-Bus master.

conditions or by exceeding the permissible
voltage range.
Before connecting the device to the supply
voltage, please check:
•
Voltage and frequency correspond to the
details on the ratings plate! Threshold
values stipulated in the user manual have
been complied with!
•
In building installations, the supply
voltage must be protected with a UL/IEC
approved circuit breaker / a fuse!
•
The circuit breaker
-
must be easily accessible for the user
and be installed close to the device.
-
must be labelled for the relevant device.
•
Do not connect the supply voltage to the
voltage transformers.
•
Provide a fuse for the neutral conductor
if the source's neutral conductor
connection is not earthed.
The supply voltage level for your device is
specified on the rating plate.
After connecting the supply voltage, an indication
is shown on the display. If no indication appears,
check whether the supply voltage is within the
rated voltage range.

Current measurement I1, I2, I3
The UMG 96 RM-M
• enables current measurements via current
transformer only.
• enables the connection of current transformers
with secondary currents of ../1 A and ../5 A.
• has the current transformer ratio 5/5 A set as
standard.
• measures AC currents, does not measure DC
currents!
c
WARNING!
Risk of injury due
to electric voltage!
Serious bodily injury or death can result from:
• Contact with bare or stripped live wires.
• Current measurement inputs that are
dangerous to touch on the device and on the
current transformers.
De-energise your device before starting
work! Check that it is de-energised.
Earth your system! Use the earth connection
points with earthing symbols for this!
Earth the secondary windings of current
transformers and all of the metal parts of the
transformer that could be touched!
c
WARNING!
Risk of injury due to
large currents and high
electric voltages!
Current transformers operating with an open
secondary circuit (high voltage peaks) can result
in serious or even fatal injuries.
Avoid open operation of the current transformers -
short-circuit unloaded transformers!

The tree structure combines the star and line structure:
• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus
segments are usually affected in the event of a fault.
• Connect M-Bus devices in star (1),
line (2) or tree structures (3).
• Each M-Bus device has its own address
within the bus structure.
• Divide (expand) bus structures into individual
bus segments with repeaters (line amplifiers).
• Up to 250 subscribers can be connected
together in a single bus segment (depending
on the M-Bus master).
• The bus structures ensure that the system
remains stable when M-Bus devices are
exchanged.
• The bus structure is out of operation during
a replacement of the M-Bus master.

Voltage measurement connection variants
Current measurement I1, I2, I3
The UMG 96 RM-M
• enables current measurements via current
transformer only.
• enables the connection of current transformers
with secondary currents of ../1 A and ../5 A.
• has the current transformer ratio 5/5 A set as
standard.
• measures AC currents, does not measure DC
currents!
c
WARNING!
Risk of injury due
to electric voltage!
Serious bodily injury or death can result from:
• Contact with bare or stripped live wires.
• Current measurement inputs that are
dangerous to touch on the device and on the
current transformers.
De-energise your device before starting
work! Check that it is de-energised.
Earth your system! Use the earth connection
points with earthing symbols for this!
Earth the secondary windings of current
transformers and all of the metal parts of the
transformer that could be touched!
c
WARNING!
Risk of injury due to
large currents and high
electric voltages!
Current transformers operating with an open
secondary circuit (high voltage peaks) can result
in serious or even fatal injuries.
Avoid open operation of the current transformers -
short-circuit unloaded transformers!

List of the data points
Measuring the signal level
The data transfer in the M-Bus network takes place
through a modulation of the supply voltage.
The voltage is
• 36 V for a high signal
• 24 V for a low signal
The slave device responds to the master via
the modulation of its current consumption.
The modulation of the current consumption is
• 1.5 mA for a high signal
• 11-20 mA for a low signal

The tree structure combines the star and line structure:
• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus
segments are usually affected in the event of a fault.
• Connect M-Bus devices in star (1),
line (2) or tree structures (3).
• Each M-Bus device has its own address
within the bus structure.
• Divide (expand) bus structures into individual
bus segments with repeaters (line amplifiers).
• Up to 250 subscribers can be connected
together in a single bus segment (depending
on the M-Bus master).
• The bus structures ensure that the system
remains stable when M-Bus devices are
exchanged.
• The bus structure is out of operation during
a replacement of the M-Bus master.

Each M-Bus device is linked to the M-Bus
Master. By switching individual devices on and
off, it is easier to locate the fault.
2. Line structure
The M-Bus devices are connected (in series)
with the M-Bus Master:
• Economical bus structure.
• Observe possible faults due to a voltage
drop in the bus structure!
• Faults are difficult to locate.
