UMG 96RM
Product description
Intended use
The UMG 96RM 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 is suitable for installation in permanent,
weatherproof switchboards. Conducting switchboards
must be earthed. It can be mounted in any position.
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 RS485 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 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 can be used in residential and industrial
areas.

UMG 96RM
Measuring method
The UMG 96RM measures uninterrupted and calculates
all root mean squares over a 9-period interval. The UMG
96RM 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
and retrieve measured values.
• Directly on the device using two buttons.
• Via the programming software of the GridVis.
• 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 UMG 96RM using the 2 buttons.
The programming software of the GridVis has its own
"online help".
