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 PC B 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 regu-lations. Please note, that the input Lithium bat-tery 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.
?Attention!
The inputs, outputs and serial interfaces must be shielded.
?
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.

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 PC B 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.
?- 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 automatically, it is sufficient to set it into position "check", provided that the short-circuiters have been checked before.

Page 20
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.
?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.
