Generals
Receipt control
In order to ensure a perfect and safe use of the device, a
proper transport, expert storage, erection and mounting
and careful usage and maintenance are required. When it
may be supposed, that a safe operation is no longer
possible, the device has to be put out of service and be
protected against unintentional putting into service.
A safe operation can no longer be assumed, when the
device
• shows visible damage,
• does not work in spite of intact net supply,
• has been exposed to disadvantageous conditions for a
longer time (e.g. storage out of the allowed climate
without adaption to the room climate, dew etc.) or
transport use (e.g. falling from great height, even without
visible damage).
Please test the contents of delivery for completion, before
starting the installation of the device.All delivered options
are listed on the delivery papers.
Attention!
All plugs, which belong to the contents of
delivery, are plugged on the device! The 9pole
D-Sub plug for RS232 interface does not belong
to the contents of delivery.
The operating instructions also describe those
options, which are not delivered and therefore
do not belong to the contents of delivery!

Hints for usage
This device may be put into service and used by qualified
personnel according to the safety regulations and
instructions only. Please mind the additional legal and
safety regulations for the respective application.
Qualified personnel are persons, familiar with erection,
mounting, putting into service and usage of the product
and having the qualifications such as:
• education or instruction / entitlement to switch, release,
ground or characterize current circuits and devices
according to the standards of safety techniques.
• education or instruction in the care and usage of suitable
safety equipment according to the standards of safety
techniques.

Page 8 = Key 1 = Key 2 = Key 3= Maximum or consumption = Minimum or supply.
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 repeated.
There is no guarantee for devices, which are opened out
of the manufacturing works.
Repairing and calibration
Repairing and calibration work can be carried out in the
company of manufacture only.
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 cleaning.
Battery
The life expectance of the battery is 5 years minimum for
a storage temperature of +45°C. The typical life
expectance of the battery is about 8 to 10 years. The
battery is plumbed and should be exchanged in the ma-
nufacturing works only.
Waste management
The UMG 503 can be disposed as electronical waste
according to the legal regulations and recycled. Please
note, that the input Lithium battery must be disposed
separately.
Service
If you have problems, which are not described in this manual, please ask our technical support.
For further handling of your questions, please have the following at hand:
- Device description (see type plate),
- Serial number (see type plate),
- Software Release,
- Measurement and auxiliary voltage and
- Exact description of the problem.

Product description
Intended use
The UMG 503 is suited for fix mounting and the measu-
rement of voltage, current, harmonics (2nd to 20th),
power etc. in low and medium voltage switchgear. For
the operation of the UMG 503 a protective wire is
required.
The measurement is laid out for one phase and three
phase systems with or without neutral conductor (three
wire measurement). If the measurement should be carried
out via two voltage transformers only, the option "three
wire measurement" is required.
Alternating voltages (50Hz/60Hz) up to 500VAC against
ground and 870VAC between the outer conductors can
be connected directly. The voltage measurement inputs
are not separated galvanicly and must be connected to
the UMG 503 via external prefuses M2A.
The current measurement is carried out via a ../5A or ../
1A current transformer. In networks with a voltage up to
150 VAC against ground currents up to 6 A can be
connected to the UMG 503 directly and measured as
well.
The connection of the auxiliary voltage, the measure-
ment inputs etc. are on the rear side via all-insulated plug
connectors.
The auxiliary voltage must be connected to the building
installation via a separation (switch or power switch) and
a 10 A overload protection.
Attention!
Measurement in systems with pulse load is not
possible, because no continuous scanning of the
measuring signals is carried out.
Functional description
The electronical three phase measurement system
determines and digitalizes the effective values of voltages
and currents in 50/60 Hz networks.
Two random test measurements are carried out each
second on all current and voltage measuring inputs.
Signal interruptions, which are longer than 500ms are
surely recognized. For each random test two periods are
scanned. From those sampled values the microprocessor
calculates the electrical magnitudes.
These measured values are indicated within the
programmable display.
Highest values, lowest values and programming data can
be saved in a battery buffered storage. Selected measu-
red values will be saved with date and time in a ring
buffer.

Putting into service
Auxiliary voltage
The input of the auxiliary voltage (terminals 14, 15) of
the UMG 503 is suitable for rated voltages up to 300VAC
against ground (PE). Higher voltages between auxiliary
voltage and ground can damage the UMG 503. To avoid
overvoltage, auxiliary voltage should be earthed.
Please also note the following:
- The wiring for the auxiliary voltage must be suited for
operating voltage up to 300VAC against ground.
- The auxiliary voltage must be protected with a fuse,
which should be in the range of 2...10A.
- A switch or power breaker must be provided for the
auxiliary voltage within the installation.
- The switch must be installed near the device and must
have an easy access for the user.
- The switch must be marked as a breaker for this device.
- Please ensure, that voltage and frequency match the
type plate before connecting it to the auxiliary voltage!
- The device may be operated with earthed housing only!
- Conductors with single solded wires are not suited for
connection to screw clamps!
- The screw clamps may only be connected in dead
condition.
Measuring voltage
The wires for the measuring voltage must be suitable for
up to 500VAC against ground and 870VAC phase to
phase.
Attention!
For the connection examples 5 and 6, the option "three
wire measurement" is required. In mains without neu-
tral conductor, voltage transformes must be connected
according to the respective connection example.
Testing current
Current transformers of .../5A or .../1A can be connected
directly to the current inputs of the UMG 503.
Attention!
Current transformers can lead voltage, which
can be live and should be earthed.
RS485 Interface cable
Bus structure
All devices are connected in bus structure (line). In one
segment up to 32 participants can be connected. At the
beginning and the end of one segment, the cable is
terminated with resistors. Within the UMG 503, these
resistors can be activated with two plug bridges.
For more than 32 participants, you must use a repeater
(line amplifier) to connect the single segments.
Protection
For the connection via RS485 interface, you must use a
twisted pair and protected cable. To achieve a sufficient
protection result, the protection must be connected to
housing or cabinet parts at both ends of cable with large
surface.
