Hints for maintenance
Before delivery the device is tested in various
safety checks and marked with a seal. If the
device is opened, these checks must be re-
peated.
There is no guarantee for devices, which are
opened out of the manufacturing works.
Repairing and calibration
Maintenance and calibration can only be carried
out at manufacturer's end.
Face plate
The cleaning of the front foil must be done with
a soft cloth using a common cleansing agent.
Acid or acidic agents may not be used for clean-
ing.
Battery
On the additional PCB 1 (option), there is a
Lithium battery. The life expectance of the bat-
tery at storage temperature +45°C is a minimum
of 5 years. The typical life expectance is
between 8 and 10 years.
If the battery voltage is too low after net return,
the display shows the warning "Err 320".
For safety reasons, the battery should be ex-
changed in the manufacturing works only!
Waste management
The UMG96S can be disposed and recycled as
electronical waste according to the legal regula-
tions. Please note, that the input Lithium battery
must be disposed separately.

Product description
Intended use
The UMG96S has been designed for a fixed in-
stallation in panels, measuring voltage, current,
power etc. in low voltage switchgear. The meas-
urement is laid out for three phase systems with
neutral conductor (TN and TT networks).
The UMG96S gets its operating voltage from the
measuring voltage and can be delivered for
operating voltage of 150V and 300V. The 300V
standard version, measurement and operation
voltage (50Hz/60Hz) up to 300VAC against
ground and 520VAC phase to phase can be
connected directly. The 150V special version,
measurement and operating voltage (50Hz/
60Hz) up to 150VAC against ground and
240VAC phase to phase can be connected di-
rectly.
The measurement and operational voltage must
be connected to the UMG96S via a separation
(circuit breaker or power switch) and a fuse (2-
10A) within the installation. The separation
(circuit breaker or power switch) must be near
to the instrument and easy to reach.
The connection of the measurement and oper-
ating voltage is carried out on the backside of
the UMG96S via touch proof spring terminal. To
the current inputs, either .../5A or .../1A trans-
formers can be connected.
Attention!
Measurement in systems with pulse load
is not possible, because no continuous
scanning of the measuring signals is car-
ried out.
m
Attention!
The inputs, outputs and serial interfaces
must be shielded.
m
Attention!
The connection of the neutral conductor
N is absolutely neccessary.

Functional description
The three phase electronic measuring system
detects and digitizes the true rms values of al-
ternating voltage and current in 50/60Hz net-
works.
The operating voltage of the UMG96S is taken
from the measuring voltage L1-N, L2-N and L3-
N. Devices for the measurement in 230V/400V
networks, at least one phase must be within the
rated range. Instruments for measurement in
58V/100V or 63V/110V networks, at least two
phases must be within the rated voltage range.
Either .../5A or .../1A transformers can be con-
nected to the current inputs. In networks with
150VAC against ground, currents up to 5A can
be connected directly to the UMG96S.
Each second, one sample measurement is car-
ried out at all current and voltage inputs. Volt-
age interruptions longer than one second are
safely recognized. For each sample, 6 periods
are scanned. From these values, the inserted
microprocessor calculates the electrical quanti-
ties. The measured values can be indicated in
the measured value displays. The energy and
minimum and maximum values as well as the
programming data are stored every 5 minutes
in a none volatile memory (EEPROM).
The scanning frequency for all measuring inputs
is calculated from the net frequency of phase
L1. For a net frequency of 50Hz, the scanning
frequency is 2.5kHz and for a net frequency of
60Hz, the scanning frequency is 3.0kHz. If
voltage in L1 is smaller than 50V, the UMG96S
uses the last measured net frequency for the
calculation of the scanning frequency.

as operating voltage and can be delivered in the
versions 150V and 300V. The delivered version
is indicated on the type plate of UMG96S.
Please ensure, that the local net conditions
match the numbers on type plate before con-
nection.
300V standard version
In 300V standard version, the UMG96S can
measure voltage up to 300VAC against ground.
At leats one phase (L) of the UMG96S and the
neutral N must be connected and the connected
voltage must be within the measurement and
operation voltage range.

150V special version
In 150V special version, the UMG96S can
measure voltage up to 300VAC against ground.
At least 2 phases (L) of the UMG96S must be
connected, and the connected voltage must be
within the measurement and operation voltage
range.
Measuring range L-N : 25 .. 140V AC

Installation
Mounting
The UMG96S is designed for a fix installation in
low and medium voltage systems. The mount-
ing position is random.
Measurement and operation
voltage
The UMG96S gets its operating voltage from the
measuring voltage. The measurement is
designed for three phase systems with neutral
conductor (TN and TT networks). The measure-
ment and operational voltage must be con-
nected to the UMG96S via a separation (circuit
breaker or power switch) and a fuse (2-10A)
within the installation. The connection of the
measurement and operating voltage is carried
out on the backside of the UMG96S via touch
proof spring terminal.
300V standard version
At least one phase (L) of the UMG96S and the
neutral N must be connected and the connected
voltage must be within the measurement and
operation voltage range.
The measurement and operation voltage
range of devices without additional PCB and for
devices with additional PCB 1 (analogue output)
are:
L-N 85 .. 300V
L-L 148 .. 520V
The measurement and operating voltage
range for devices with additional PCB 2
(Profibus) are:
L-N 140 .. 300V
L-L 242 .. 520V
150V special version
At least 2 phases (L) of the UMG96S must be
connected, and the connected voltage must be
within the measurement and operation voltage
range.
The measurement and operating voltage
range is:
L-N 50 .. 150V
L-L 85 .. 260V Attention!
Before connecting voltage, the device
should be deposited in the preposed in-
stallation room for at least 2 hours, in
order to create a temperature equaliza-
tion and avoid humidity or dew within the
instrument.

Attention!
The limits, mentioned under "technical
data" may not be exceeded, even not
during checking or putting into service of
UMG96S.
m
- The used cables must be suitable for a rated
voltage of 300VAC against ground.
- The measurement and operating voltage must
be protected by a fuse. The fuse must be in the
range of 2A to 10A.
- Please provide a circuit breaker or power
switch for the operating voltage.
- The switch must be near the UMG96S and
easy to reach.
- The switch must be marked as a separation for
this instrument.

Sum current measurement
If the current measurement is carried out via two
current transformers and a sum current trans-
former, the total transformer ratio must be
programmed at UMG96S.
Example: Sum current transformer
A current measurement is carried out via one ct
with a ratio of 1000/5A and one ct with a ratio of
1000/5A. The current measurement is carried
out via a sum current transformer 5+5/5A.
The UMG96S must be programmed as follows:
Primary current: 1000A + 1000A = 2000A
Secondary current: 5A

Current measurement
The current measurement is carried out via cur-
rent transformers of either ../5A or ../1A. If the
current must be measured by an Amperemeter
additionally, it must be connected in series to the
UMG96S.
In networks with voltage up to 150VAC against
ground, currents up to 5A can be connected di-
rectly to the UMG96S.

Attention!
The secondary connections of the current
transformer must be short-circuited, be-
fore the wires that lead to the device are
interrupted!
If a testing switch is available, which short-
circuits the secondaries of the cts auto-
matically, it is sufficient to set it into posi-
tion "check", provided that the short-
circuiters have been checked before.

Serial interfaces
Depending on the version the UMG96S may
have up to three serial interfaces. The serial in-
terfaces are not separated galvanically.
The RS232 and RS485 cannot be operated at
the same time!
If both interfaces are connected, the device rec-
ognizes by the signal level, if an instrument is
connected to the RS232. The data transmission
is carried out via RS232 only.
If no device is recognized at RS232, data trans-
mission is active on RS485 interface.
m
Inputs and outputs
The UMG96S offers the possibility of assigning
different functions to the outputs of the different
versions (options).
Terminal 12, for example, can have the function
"pulse output" and terminal 13 can have the
function "digital input". Please note, that both
circuits have a common supply +24VDC, termi-
nal 11.
Only one function can be assigned to each ter-
minal 12 and 13.
