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

UMG 96RM-P/-CBM
Product description
Proper use
The UMG 96RM-P/-CBM 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-P/-CBM 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-P/
-CBM 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-P/-CBM can be
employed both domestically and in industry.

UMG 96RM-P/-CBM
Measuring method
The UMG 96RM-P/-CBM measures uninterrupted and
calculates all root mean squares over a 10/12-period
interval. The UMG 96RM-P/-CBM measures the true
root mean square (TRMS) of the voltages and currents
applied to the measuring inputs.
Operating concept
There are several ways to program the UMG 96RM-P/
-CBM and retrieve measured values.
• Directly on the device using two buttons
• Via the programming software of the GridVis
• Through the device‘s homepage
• Via the RS485 interface with the Modbus protocol.
Data can be changed and retrieved with the help of the
Modbus address list (stored on the accompanying
data carrier).
These operating instructions only describe the operation
of the 96RM-P/-CBM using the 2 buttons.
The programming software of the GridVis has its own
“online help”. Additional components that are not
included in the scope of deliverables will be
required for parameterisation via the RS485
interface.

Installation location
The UMG 96RM-P/-CBM is suitable for installation in
permanent, weatherproof switchboards. Conducting
switchboards must be earthed.

The UMG 96RM-P/-CBM must be installed vertically
in order to achieve sufficient ventilation. The clearance
to the top and bottom must be at least 50 mm
and 20 mm at the sides.

UMG 96RM-P/-CBM
Mounting
The UMG 96RM-P/-CBM is fixed using the mounting
clips found on the side of the switch panel. Before in-
serting the device, they should be moved out of the way
in a horizontal lever using a screwdriver, for example.
Fig. side view

with mounting clips.
Loosening the clips is
done using a screw-
driver and a horizontal
lever effect.
The fastening is then done when the device is pushed
in an the clamps lock in place when the screws are ti-
ghtened.
• Please tight the fixing screws until they contact the
mounting plate easily.
• Tighten with two further turns, the clamping screws
(are the screws tightened too much, the mounting
bracket will be destroyed)

Supply voltage
A supply voltage is required to operate the UMG 96RM-
P/-CBM. The voltage supply is connected via plug-in
terminals on the back of the device.
Before applying the supply voltage, ensure that
the voltage and frequency correspond with the details
on the nameplate!
The supply voltage must be connected via a UL/IEC
approved fuse (6 A, type C).

m• In building installations, the supply
voltage must be provided with a
disconnect switch or circuit breaker.
• The disconnect switch must be attached
near the device and must be easily
accessible by the user.
• The switch must be labelled as a
separator for this device.
