Inspection on Receipt
Fault free and safe use of this device requires
appropriate transport, proper storage, erection
and assembly as well as careful operation and
maintenance. If it can be assumed that safe
operation is no longer possible, the device must
be immediately taken out of service and se-
cured against being accidentally started up.
The device must be unpacked and packed with
the usual care, without the use of force and
only using suitable tools. The devices must be
visually inspected for perfect mechanical
condition.
It can be assumed that safe operation is no
longer possible if the device, e.g.
• has visible damage,
 despite intact mains power supply no longer
works,
 has been exposed to unfavourable conditions
(e.g. storage outside the permissible climatic
limits without adjustment to the ambient cli-
mate, condensation, or similar) for a lengthy
period or was exposed to unfavourable effects
or loads during transport (e.g. fall from a large
height even if there is no visible external dam-
age, or similar).
Please check the scope of supply for complete-
ness before you start installing the device.

Maintenance Instructions
The device is subjected to various safety
checks before delivery and marked with a seal.
If a device is opened, the safety checks must
be repeated.
We cannot provide any warranty for devices not
opened in the manufacturer’s factory.
Repair and calibration
Maintenance and calibration work can only be
carried out in the manufacturer’s factory.
Front film
The front film can be cleaned with a soft cloth
and standard household cleaning agent. Do not
use acids and products containing acid for
cleaning.
Battery
There is a lithium battery on the additional
printed circuit board 1 (option). The life expect-
ancy of the battery is at least 5 years, at a stor-
age temperature of +45°C. The typical life ex-
pectancy of the battery is 8 to 10 years.
For safety reasons, the battery can only be re-
placed in the manufacturer’s factory!
Disposal
The UMG96S can be reused or recycled as
electronic scrap in accordance with the legal
provisions. Please note that the lithium battery
installed on the additional circuit board 1 (op-
tion) must be disposed of separately.

Product Description
Intended use
The UMG96S is intended for fixed, permanent
and weather protected use in switchboards and
for the measurement of voltage, current, power,
etc. in low voltage switchgear. The measure-
ment is designed for 3-phase systems with
neutral conductor (TN and TT systems).
The UMG96S is available in 150V and 300V
measuring-circuit versions. In the standard
300V version, measuring-circuit voltages
(50Hz/60Hz) up to 300VAC can be directly con-
nected to earth and 520VAC phase-to-phase
and in the 150V special version measuring-
circuit voltages (50Hz/60Hz) up to 150VAC can
be connected to earth and 240VAC phase-to-
phase.
The measuring and auxiliary voltages must be
connected to the UMG96S via a disconnecting
device (switch or power circuit breaker) and an
overcurrent protective device (2-10A) in the
building installation. The disconnecting device
(switch or power circuit breaker) must be lo-
cated close to the UMG96S and be easily ac-
cessible.
The measuring-circuit voltages and auxiliary
voltage are connected on the rear of the
UMG96S via shockproof spring-loaded termi-
nals.
../5A and ../1A current transformers can be op-
tionally connected to the current measurement
inputs.
Important!
Measurement of systems with packet
controls is only conditionally possible,
as there is no continuous scanning of
the measurement signals.
m
Important!
The inputs and outputs and the serial in-
terfaces must be shielded.
m
Important!
The neutral conductor N must always
be connected.

Functional principle
The three-phase electronic measuring system
records and digitises the effective values of al-
ternating voltages and alternating currents in
50Hz/60Hz systems.
../5A or ../1A current transformers can be op-
tionally connected to the current measurement
inputs. In systems with voltages up to 150VAC
to earth, currents up to 5A can also be directly
connected to the UMG96S.
Each second, one sample measurement each
is taken at all current and voltage measurement
inputs. Measurement signal interruptions last-
ing more than one second are reliably detected.
6 periods are scanned for each sample. The in-
stalled microprocessor calculates the electric
variables from the scanned values. The meas-
ured values can be displayed in the measured
value displays. The work and minimum and
maximum valves are stored every 5 minutes in
a non-volatile memory (EEPROM) and the pro-
gramming data is stored there immediately.
The scanning frequency for all measurement
inputs is calculated from the phase L1 system
frequency. For a system frequency of 50Hz the
scanning frequency is 2.5kHz and for a system
frequency of 60Hz the scanning frequency is
3.0kHz. If the voltage in phase L1 is smaller
than 50V, the UMG96S uses the last measured
system frequency to calculate the scanning fre-
quency.

Installation Instructions
I n s t a l l e d p o s i t i o n
The UMG96S is intended for permanent instal-
lation in low and medium voltage switchgear. It
can be installed in any position.
Auxiliary voltage
The auxiliary voltage must be connected to the
UMG96S via a disconnecting device (switch or
power circuit breaker) and an overcurrent pro-
tective device (2-10A) in the building installa-
tion.
Measuring-circuit voltage
The measurement is designed for 3-phase sys-
tems with neutral conductor (TN and TT sys-
tems). The measuring-circuit and auxiliary
voltages are connected on the rear of the
UMG96S via shockproof spring-loaded termi-
nals.
300V standard version
The measuring-current and operating voltage
ranges for devices without additional printed
circuit boards and for devices with addi-
tional circuit board 1 (analog output) are:
L-N 50 .. 300V
L-N 87 .. 520V
150V special version
The measuring-circuit and operating voltage
ranges are:
L-N 25 .. 150V
L-N 40 .. 260V
Important!
Before the device is connected to the
voltage for the first time, it must have
been in the operating room for at least
two hours in order for the temperature to
adjust to the ambient conditions and to
avoid moisture and condensation.
m
Important!
The limit values given in the technical
specifications may not be exceeded, not
even during testing and putting into
service of the UMG96S.
m
- The wiring cables for the operating voltage
must be suitable for rated voltages up to
300VAC to earth.
- The operating voltage must be secured with a
fuse. The fuse must lie within the range of 2A
to 10A.
- The building installation must include a switch
or power circuit breaker for the operating volt-
age.
- The switch must be installed near the device
and be easily reachable by the user.
- The switch must be labelled as a discon-
necting device for this device.

Page 19
Summation current measurement
If the current is measured via two current trans-
formers, the total transformation ratio of the
current transformers must be programmed in
the UMG96S.
Example: Summation current transformer
Each current measurement is taken via a cur-
rent transformer with a transformation ratio of
1000/5A and a current transformer with a trans-
formation ratio of 200/5A. The summation
measurement is performed with a 5+5/5A sum-
mation transformer.
The UMG96S must then be set as follows:
Primary current: 1000A + 200A = 1200A
Secondary current: 5A

Current measurement
The current is optionally measured via a ../5A
or ../1A current transformer. If, in addition to the
UMG96S, the current has to be measured with
a ampere meter, this must be connected in se-
ries with the UMG96S.
In systems with voltages up to 150VAC to
earth, currents up to 5A can also be directly
connected to the UMG96S and measured.

Important!
The secondary connections of the current
transformer must be short-circuited to it
first before the current supply leads to the
device are disconnected!
If a testing switch is available, which au-
tomatically short circuits the current
transformer’s secondary leads, it is suffi-
cient to place this in the „test“ position,
provided the short-circuiters have been
tested first.

Serial interfaces
The various design versions of the UMG96S
have up to two serial interfaces.
The serial interfaces are not isolated from each
other.
Inputs and outputs
In the various design versions (options) of the
UMG96S, different functions can be assigned
to the outputs.
For example, terminal 12 can be assigned to
the pulse output function and terminal 13 the
digital input function. Here it must be ensured
that both electric circuits have a common im-
ported supply via terminal 11 (+24V).
Only one function can ever be assigned to ter-
minal 12 and terminal 13.
