UMG 512
Product description
Proper use
The UMG 512 is intended for the measurement
of voltage quality according to EN61000-4-30 in building
installations, on distribution units, circuit breakers
and busbar trunking systems.
Measured voltages and measured currents must derive
from the same network.
The UMG 512 is suitable for integration into fixed and
weatherproof switch panels in indoor areas. Conductive
switch panels must be earthed.
The UMG 512 can be used in 2, 3 and 4-conductor
networks and in TN and TT networks.
The current measurement inputs 1–4 of the UMG 512
are connected via external ../1A or ../5A current
transformers.
Measurements in medium and high-voltage networks are
always performed via current and voltage transformers.
The measurement results can be displayed and read
out and further processed via the interfaces (Ethernet,
Modbus, Profibus).
The UMG 512 can be used in industrial and domestic
settings.
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 512 does not provide protection against
electric shock!
The residual current monitoring is performed via
the current measurement inputs I5 and I6 via an
external residual current transformer with a rated current
of 30 mA.
mResidual current monitoring monitors
residual currents via external current
transformers and can trigger a warning
impulse when a response threshold
is exceeded. The device is thus not an
independent protective device!

UMG 512
Measuring process
The UMG 512 measures continuously and calculates
all effective values over a 200 ms interval. The device
measures the real effective value (TRMS) of the voltages
and currents connected to the measurement inputs.
Operating concept
You can program and call up the measured values via
many routes using the UMG 512.
• Directly on the device via 6 buttons and the display
• Using the GridVis programming software.
• Using the device homepage
• 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 operation manual only describes how to operate the
UMG 512 using the six buttons.
The GridVis programming software has its own "online
help" system.
GridVis network analysis software
The UMG 512 can be programmed and read out
using the GridVis network analysis software included
in the scope of the delivery. For this, a PC must be
connected to the UMG 512 via a serial interface (RS485/
Ethernet).

Ethernet
The Ethernet connection of the UMG 512 is on the bottom
of the housing.
Depending on the bending radius of the Ethernet cable
and connector type, you must install a connection area
below the UMG 512.
The connection area below the UMG 512 should not
be smaller than 50 mm.
Mounting
The UMG 512 is mounted in the switchboard with two
mounting clips that are installed at the top and bottom
of the device.

Installation
Ground wire connection
Use a ring cable lug for connecting the protective
conductor to the UMG 512.
Supply voltage
The UMG 512 needs supply voltage to operate. The type
and amount of the supply voltage required is specified
on the rating plate. The supply voltage is connected
on the rear side of the device via terminal blocks.
Before connecting the supply voltage, ensure that
the voltage and frequency correspond to the details
on the rating plate!
The supply voltage must be connected through a UL/IEC
approved fuse.
cCaution: Risk to life!
The ground wire connection on the device
must be connected with the system
earthing. Fig. connection example of the supply voltage

m• If installed in a building, a disconnector
or circuit breaker must be provided for
the supply voltage.
• The disconnector must be installed
near the device and easily accessible
to the user.
• The switch must be marked as the circuit
breaker for this device.
• Voltages which are over the permitted
voltage range can destroy the device.
cPlease note!
The inputs for the supply voltage are
hazardous if touched!
cPlease note!
Make sure to observe the specifications
for the supply voltage that are provided
on the rating plate of the UMG 512.

UMG 512
Voltage measurement
Three-phase 4-conductor systems
The UMG 512 can be used in three-phase 4-conductor
systems (TN, TT networks) with an earthed neutral
conductor. The bodies of the electrical system are
earthed.
The voltage measurement in the UMG 512 is designed
for the overvoltage category 600V CAT III (measurement
voltage surge 6kV).
Three-phase 3-conductor systems
The UMG 512 is only suitable to a limited extent for use
in IT networks, since the measured voltage relative to the
housing potential is measured and the input impedance
of the device creates residual current against the earth.
The residual current can trigger the insulation monitoring
in IT networks.
The connection variants with voltage transformers are
suitable for unlimited use in IT networks.

UMG 512
Voltage measurement inputs
The UMG 512 has four voltage measurement inputs (V1,
V2, V3, V4).
Voltage swell
The voltage measurement inputs are suitable for
measurements in networks where overvoltages
of overvoltage category 600V CATIII can occur.
For measurement with the supporting
measurement (V4), a voltage must be
connected to the baseline measurement
for frequency determination.
m
If the baseline measurement (inputs
V1-V3) is connected to a three-phase
3-conductor network, the supporting
measurement (input V4) can no longer be
used as a measurement input.
