Incoming goods inspection
The proper and safe operation of this device
requires appropriate transport, proper storage,
installation and assembly as well as careful operation
and aintenance. When it is assumed that safe operation
is no longer possible, the device must immediately be
taken out of operation and secured against accidental
start-up.
Unpacking and packing must be carried out with
the usual care, without the use of force and only with
the use of suitable tools. The devices must be visually
inspected for proper mechanical condition.
It can be assumed that safe operation is no longer
possible if the device, e.g.
• shows visible damage,
• does not work despite intact power supply,
• and was exposed to unfavourable conditions
(e.g. storage outside of the permissible climatic
limits without adaptation to the ambient climate,
condensation, etc.) or transport stresses (e.g. falling
from a great height even without exterior visible
damage, etc.) for prolonged periods.
• Please check that the delivery is complete before you
begin with installation of the device.
CAll supplied screw terminals are
attached to the device.
About these operating instructions
These operating instructions are part of the product.
• Read the operating instructions prior to using
the device.
• Keep the operating instructions at hand throughout
the entire service life of the product and keep ready
for referencing.
• Hand over the operating instructions to each
subsequent owner or user of the product.

UMG 96RM-M
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”.
