UMG 96RM-P/-CBM
Incoming inspection
The prerequisites of faultless, safe operation of this
device are proper transport and proper storage,
setup and assembly, as well as careful operation and
maintenance. If it can be assumed that risk-free operation
is no longer possible, the unit must be immediately put
out of operation and secured against being put back into
operation again.
The packing and unpacking must be carried out with
the customary care without the use of force and only
using suitable tools. The devices should be visually
checked for flawless mechanical condition.
It can be assumed that risk-free operation is no longer
possible if the device, for example,
• has visible damage
• no longer works despite the mains power supply
being intact
• has been exposed to long-term adverse conditions (e.g.
storage outside the permissible climate limits without
being adapted to the room climate, condensation etc.)
or rough handling during transportation (e.g. fall from a
height, even if there is no visible external damage etc.)
• Please check the scope of deliverables for
completeness before you start with the installation of
the device.

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

UMG 96RM-P/-CBM
Measuring process
The UMG 96RM measures continuously and calculates all
effective values over a 9 period interval. The UMG 96RM
measures the real effective value (TRMS) of the voltage
and current connected to the measurement inputs.
Parameterising
You can parameterise the UMG via buttons 1 and 2 or
via the RS485 or USB interface.
You can only parameterise a small portion of the functions
directly on the device via the buttons. The list of functions
can be found in table 1 of the installation instructions for
the basic device.
All functions can be parameterised via the serial
interfaces and with the GridVis programming software.
Only the RS485 interface is available on
the basic device.
C
Additional components that are not
included in the scope of deliverables will
be required for parameterisation via the
RS485 interface.
