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 val-
ues 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”.

Connection options
Connection of a UMG 96RM-M to a PC via a M-Bus
signal converter (RS232):
Netzanalysesoftware GridVis
The UMG 96RM-M can be programmed and read with
the GridVis network analysis software (Download: www.
janitza.com). For this a PC must be connected via a serial
interface (RS232 / USB) for example via an M-Bus Mas-
ter (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 Grid-
Vis software does not support this function!
It is not possible to read out M-Bus devices provided by
other manufacturers using the GridVis software!
