Intended useInstallationThe UMG507 is suitable for installation infixed and weatherproof control panels. Con-ductive control panels must be earthed. Dueto its high immunity the UMG507 is suitablefor continuous, unmonitored operation.

MeasurementThe UMG507 is inetnded for the measure-ment of electrical variables such as voltage,current, power, etc. in low-voltage switchgear.Measured values are saved adn can be readout through serial interfaces. The voltage andcurrent measurement inputs are continuouslyscanned. Brief interruptions up to a half-waveare reliably detected.The applied voltages must lie within the meas-uring and supply voltage range given on therating plate.The measuring and supply voltages must beconnected to the UMG507 via a disconnect-ing device (switch or circuit-breaker) and anovercurrent protection device (2-10A) in thebuilding installation. The disconnecting devicemust be near the UMG507 and be easilyreached by the user. The disconnecting de-vice must be labelled for the device.Either ../5A or ../1A current transformers canbe optionally connected to the current meas-urement inputs.

Medium and high-voltage systemsMeasurement in medium and high-voltagesystems is generally carried out using currentand voltage transformers. Special safety pro-visions are applied to these, which are not dis-cussed in any greater detail here.

TN and TT systemsMeasurement is designed for 3-phase sys-tems with neutral conductors (TN and TT sys-tems).

Fig. Block diagram, UMG507 in the TN sys-tem.

Fig. Block diagram, UMG507 in the IT systemwith N.

Fig. Block diagram, UMG507 in the IT systemwithout N.

IT systemsThe UMG507 is only conditionally suitable foruse in IT systems, as the measurement volt-age is measured at the housing potential andthe input impedence of the device causes aleakage current to the earthing. The leakagecurrent can cause the insulation monitoring inIT systems to respond. It must also be en-sured that the maximum permissible voltageat the inputs of the UMG507 are not ex-ceeded to earth (e.g. in case of a phase-to-earth fault).The connection options shown in Fig. 4.1b(with PEN conductor) or Fig. 4.6a (without aPEN conductor) are suitable for IT systemswithout restriction. Here the IT system is insu-lated through the use of voltage transformers.

It is absolutely necessary to connectthe PEN conductor N.

Installation locationThe UMG507 is intended for permanent in-stallation in low and medium-voltageswitchgear. It can be installed in any position.

Protective conductorA protective conductor according to the validsafety regulations must be connected at thescrew provided on the rear of the device be-fore the remaining connections with the de-vice can be made.

Supply voltageAn operating voltage is required to run theUMG507. The type and strength of the oper-ating voltage required for the UMG507 isnoted on the rating plate.

230V Standard version120V Special version 63V Special version

Higher voltages between the terminals 31/32and earth (PE) can severely damage theUMG507. In order to prevent an overvoltagethe operating voltage should be earthed.The operating voltage is connected at termi-nals 31 and 32. A maximum voltage of300VAC may occur between the terminals 31and 32 (operating voltage) and earth (PE).

Attention!- The wiring cables for the operating voltagemust be suitable for nominal voltages up to300VAC to earth.

- The operating voltage must be fused. Thefuse must lie within the range from 2A to 10A.

- The building installation must include aswitch or circuit-breaker for the operatingvoltage.

- The switch must be installed close to thedevice and be easy for the user to reach.

- The switch must be labelled as a discon-necting device for this device.

- Before applying the operating voltage en-sure that the voltage and frequency comply tothe values given on the rating plate!

- The device may only be run with an earthedhousing!

- Conductors with soldered individual wiresare not suitable for connections at screw-type terminals!

-The pluggable screw terminals may only beplugged in when no voltage is applied.

- Only pluggable screw terminals with thesame number of poles and the same type(with/without threaded connection) may beconnected with each other.

Voltages which lie above the permis-sible voltage range can severely dam-age the device.

Connection optionsThe UMG507 can measure in systems with Nand even in systems without N through twovoltage transformers. Measurement in sys-tems with L1/L2/L3 and N (PEN) is calledfour-wire measurement here. Measurementin systems with L1/L2/L3 but without N iscalled three-wire measurement.The UMG507 is preset in the factory formeasurement in systems with N (four-wiremeasurement).

Voltage measurementThe UMG507 is suitable for measuring alter-nating voltages of up to 500VAC to earth and870VAC phase-to-phase. The wiring cablesfor the measured voltages must be suitabelfor voltages up to 500VAC to earth and870VAC phase-to-phase.

Attention!The UMG507 is not suitable for meas-urement of direct voltages.

Voltages over 500VAC to earth mustbe connected through a voltage trans-former .

The supply conductors for voltagemeasurement in UMG507 must beprotected by an overcurrent protectivedevice.

Total current measurementIf the current measurement takes placethrough two current transformers, the totalconversion ratio of the current transformersmust be programmed in the UMG507.

Example: summation current transformerCurrent measurement takes place using onecurrent transformer with a conversion ratio of1000/5A and one current transformer with aconversion ratio of 200/5A. The total measure-ment is carried out using a summation trans-former 5+5/5A.The UMG507 must then be set as follows:

Primary current: 1000A + 200A = 1200ASecondary current: 5A

Fig.: Example, current measurement usingsummation transformer.

The secondary connections of the cur-rent transformer must be short-circuited at it before the current supplyconductors to the device are discon-nected!If a test switch is available, which au-tomatically short-circuits the currenttransformer supply conductors, it issufficient to place in in the „Test“ posi-tion, provided that the short-circuitershave been previously tested.

�

Fig.: Example, current measurement usingadditional ammeter.

Current measurementThe UMG507 is designed for the connectionof current transformers with secondary cur-rents of ../1A and ../5A. Only alternating cur-rents can be measured, not direct currents.Each current measurement input can be per-manently loaded with 6A or loaded for 1 sec-ond with 60A. In systems with voltages up to150VAC (CATIII) or 300VAC (CATII) to earthcurrents of up to 5A can also be directly con-nected to the UMG507 and measured.

If the current has to be measured with anammeter in addition to the UMG507, this mustbe connected in series with the UMG507.

Installation

RS485Terminal resistorsAll devices are connected in a bus structure(line). Up to 32 stations can be connected to-gether in one segment. The cable is termi-nated with resistors at the start and end of asegment.If there are more than 32 stations, repeatersmust be used in order to connect the indi-vidual segments.

ShieldingA twisted-conductor and shielded cable mustbe provided for connections through theRS485 interface. In order to achieve sufficientscreening effectiveness, the screening mustbe connected to large areas of the housing orcabinet parts at both ends of the cable.

Cable typeRecommended cable types:Unitronic Li2YCY(TP) 2x2x0.22 (Lapp cable)Unitronic BUS L2/FIP 1x2x0.64 (Lapp cable)

Cable length1200m for a baud rate of 38.4k.

RS232The achievable distance between two RS232devices depends on the cable used and thebaud rate. As a rule of thumb, for a transferrate of 9600 baud the distance should not ex-ceed 15m to 30m.The permissible ohmic load must be greaterthan 3kOhm and the capacitive load causedby the transmission cable must be smallerthan 2500pF.The 2m connection cable included in theRS232 interface scope of supply can be usedto transfer data with the maximum settablebaud rate of 38.4kBit/s.

RS485 ProfibusThe profibus connection of the UMG507 isdesigned as a 9 pin DSUB socket. We recom-mend a 9 pin profibus connector e.g. from thefirm Phoenix, type „SUBCON-Plus-ProfiB/AX/SC“ with the product number 2744380 for theconnection.

Installation

Connection of the bus cablesThe incoming bus cable is connected at theterminals 1A and 1B. The bus cable for thenext device in the line is connected at the ter-minals 2A and 2B. If there are no more de-vices in the line, the bus cable must be termi-nated with resistors (switch to ON).In the switch setting ON the terminals 2A and2B are switched off for the continued bus ca-ble.

Apply measurement currentThe UMG507 is designed for the connectionof ../1A and ../5A current transformers.Only alternating currents can be measuredthrough the current measurement inputs, notalternating currents. Current transformer ter-minals must be earthed on the secondaryside.Current transformers which are not loaded onthe secondary side can result in dangerouscontact voltages and must therefore be short-circuited.Connect the individual current transformers tothe UMG50 and compare the current dis-played with the applied current. The currentdisplayed by the UMG507 must correspond tothe input current, taking into account the cur-rent transformer transformation ratio.The current transformer rator is set in the fac-tory to 5/5A and may have to be adapted tothe current transformers used.If the current transformer is short-circuited onthe secondary side, the UMG507 must dis-play approx. zero amperes in the correspond-ing external conductor.

Install deviceThe UMG507 is intended for installation inlow-voltage distribution boards, in which maxi-mum overvoltages in the overvoltage categoryIII occur.It can be installed in any position. The en-closed fixing branckets are to be used in thefront panels or switchgear cabinet doors.

Connect deviceApply supply voltageThe size of the measuring and operating volt-age for the UMG507 is given on the ratingplate.Measurement and operating voltages, whichdo not correspond to the values given on therating plate, malfunctions and severe damageto the device can result.The wiring cables for the measuring voltagesto the UMG507 must be suitable for voltagesup to 300V to earth and 520V phase-to-phase.After switching on the measuring and operat-ing voltage specified on the rating plate of theUMG507, all the segments appear in the dis-play. About two seconds later the UMG507switches to the first measured value display.If no display appears, check whether the op-erating voltage lies within the nominal voltagerange.

Initial Startup

Apply measurement voltageThe UMG507 is suitable for the measurementof voltages of up to 500VAC to earth and870VAC phase-to-phase.The UMG507 is not suitable for the measure-ment of direct voltages. Voltages over 500VACto earth must be connected through voltagetransformers.After connecting the measurement voltage,the measured values for the voltages L-N andL-L displayed by the UMG507 must be com-pared with those at the voltage measurementinput. If a voltage transformer factor is pro-grammed, this must be taken into account inthe comparison.

PasswordIn order to make it difficult to accidentallychange the programmed data using the key-board or the WEB interface, a password anda password mode can be programmed. It isonly possible to switch to the prammingmenus and to change the programmed dataafter the password has been correctly en-tered.

In the factory, no password (0000) and nopassword mode (0000) are preset. In thiscase the password query is skipped.

If a password has been changed andis no longer known, the device mustbe sent to the manufacturer.

�

Setting range:Password = 0 .. 9999Password mode = 0, 1, 2, 128, 129, 130

Factory setting:Password = 0Password mode = 0

Password = 0000 => no password= 1-9999 => with password

Configuration

Password modeThe password mode controls access to theUMG507 over the ethernet. The UMG507 hassix password modes:

0 - Anybody can access the UMG507 overthe ethernet.

1 - Only the host names stored in theUMG507 can access the UMG507 over theethernet.

2 - The UMG507 can only be accessedover the ethernet with a password.

VoltageIn the voltage display you should check the L-N and/or L-L voltages. If one or severalvoltages are missing here, there is possibly awiring error.If the displayed values do not correspond tothe actual voltages, check the voltage trans-former setting.

Phase sequenceIf all the voltage circuits have been connected,the UMG507 displays the phase sequence.If all the segments in the display run in aclockwise direction, a right-hand rotating fieldexists. If the segments in the display run in ananti-clockwise direction, a left-hand rotatingfield exists.

If the segments in the display are at a stand-still there is not rotating field. In this case thevoltage circuits have probably not all beenproperly connected.

PowerSelect the display of the active power of thethree phases. Assuming that there is no gen-erator operation, positive active powers of asimilar size should be displayed for eachphase. If not, the current transformers areprobably reversed or assigned to the wrongphase.

Check the total power outputsIf all voltages, currents and outputs for the re-spective outer conductors are correctly dis-played, the total power outputs measured bythe UMG507 must also be correct. To confirmthis, the total outputs measured by theUMG507 should be compared with the workof the active and reactive power meters lo-cated in the incoming supply.

Check the individual powersIf a current transformer has been assigned tothe wrong outer conductor, the correspondingpower will be incorrectly measured and dis-played.The assignment of the outer conductor to thecurrent transformer at the UMG507 is correctif there is no voltage between the outer con-ductor and the corresponding current trans-former (primary).In order to ensure that an outer conductor atthe voltage measurement input is assigned tothe correct current transformer, the respectivecurrent transformer can be short-circuited onthe secondary side. The apparent power dis-played by the UMG507 must then be approx.zero in this phase.If the apparent power is correctly displayedbut the active power is displayed with a „-“sign then the current transformer terminalsare reversed or power is supplied to the powersupply company.

CurrentSwitch to the currents display. The read offbalues should agree with the currents actuallyflowing. If not, check the wiring and the cur-rency transformer setting.

Check the current directionShort-circuit two current transformers on thesecondary side. The active power displayed inthe remaining phase of the UMG507 mustnow be positive (+) for drawing of active powerand negative (-) for supply (generator opera-tion) of active power.If no active power is displayed the assignmentof the voltages to the currents may be wrong.
