UMG 96RM-E
Product description
Proper use
The UMG 96RM-E 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-E is suitable for integration into fixed
and weatherproof switch panels. Conductive switch
panels must be earthed.
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 RS485
interface.
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 I1–I4 of the UMG 96RM-
E are connected via external ../1A or ../5A current
transformers.
By continuously monitoring the residual currents
(RCM) of an electrical system via the inputs I5 and I6,
warning pulses can be triggered if a response threshold
is exceeded. Using these, the system operator can
be alarmed before a protective equipment reacts.
The UMG 96RM-E does not provide protection against
and electric shock!
The residual current measuring is done via the current
measurement inputs I5 and I6 via an external residual
current transformer with a rated current of 30 mA.
Measurements in medium and high-voltage networks
is always done via current and voltage transformers.
mThe residual current measuring monitors
residual currents via external current
transformers and can trigger a warning
impule when a response threshold
is exceeded. Thus, the device is NOT
an independent protective device!

UMG 96RM-E
Measuring process
The UMG 96RM-E measures continuously
and calculates all effective values over a 10/12 period
interval. The UMG 96RM-E measures the real effective
value (TRMS) of the voltage and current connected
to the measurement inputs.
Operating concept
You can program and call up the measured values via
many routes using the UMG 96RM-E.
• Directly on the device via 2 buttons.
• Using the GridVis programming software.
• Through the device's home page.
• Using the Modbus protocol.
You can modify and call up the data using
the Modbus address list. The list can be called
up via the device's home page and can be found
on the enclosed CD.
This manual only describes how to operate
the UMG 96RM-E using the two buttons.
The GridVis programming software has its own online
help system.
