Operation in on-linemode

Normal operationNormal AC source power is available(see figure 7).◗ lights 1 , 4 and 5 shine green onthe control panel;◗ the power necessary for the load isprovided by the normal AC source (1)through the rectifier/charger (A) and theinverter (B);◗ the rectifier/charger (A) also suppliesthe power to float charge and rechargethe battery if any.The rectifier/charger output voltage(DC) is regulated to supply:◗◗ the float-charging or the rechargingvoltage for vented lead-acid or Ni/Cdbatteries,◗ ◗ a single charge voltage for sealedlead-acid batteries.

The voltages depend on the number ofbattery cells and the batterymanufacturer. Factory set, they mayalso be adjusted by after-sales supporttechnicians.An electronic board continuouslymeasures the battery temperature andautomatically adjusts the voltages.

Note:In parallel MGE™ Galaxy™ PWsystems, the power drawn by the loadis equally shared between the different

units.Operation with the normalAC source downSee figure 8.In the event of a normal AC sourcefailure or voltage outside specifiedtolerances of ±10% in amplitude (±15%optionally), the rectifier/charger (A)stops and the battery (D) supplies thenecessary backup power to the load viathe inverter (B). The battery, float-connected between the rectifier/chargerand the inverter, discharges during thisoperating mode.Lights 2 , 4 and 5 shine green.The user is warned of battery operationby the slow beeping of the buzzer 6(see figure 19) and the message"LOAD PROTECTED, BATTERYDISCHARGING", followed by theremaining backup time and the percentload.This information is also available viavolt-free changeover contacts forremote control devices.

Note:In the event of a normal AC sourcefailure, frequency converters without abattery shut down and the load is no

longer supplied.Battery timeThe available battery time during anormal AC source outage depends onthe:◗ rated capacity of the battery;◗ power consumed by the load;◗ temperature of the battery;◗ age of the battery.The specified battery time correspondsto a minimum duration at full rated load.The actual backup time can thereforebe greater if the system operates belowits full rated load during the normal ACsource outage. Operation on batterypower can be extended beyond thespecified time by reducing the loadpower consumption (by disconnectingnon-critical loads).A "low battery" warning signal is sentvia volt-free changeover contacts forremote control devices when thebattery voltage reaches a level slightlyabove the minimum level. This signalwarns the user of the imminent end ofbattery power. On the device itself, thebuzzer beeps rapidly.The message "LOW-BATTERYSHUTDOWN WARNING" is displayed,followed by the remaining backup timeand the percent load. Light 2 turns redand flashes.Battery power stops when the voltagesupplied by the battery reaches theminimum threshold (335 V). Thisresults in inverter shutdown andtransfer of the load without interruptionto the bypass AC source. Light 2shines red (not flashing). The message"LOAD NOT PROTECTED, ON-LINEMODE" is displayed and the buzzersounds continuously.If the bypass AC source also fails, theload is no longer supplied. The inverterautomatically shuts down when thetime on battery power exceeds threetimes the specified backup time.

Note:The "low battery shutdown" warningsignal can be sent with an adjustabletime delay prior to the effective end ofbattery power.Fig. 7

Operation with the normalAC source restoredSee figure 9.When normal AC source power (1) isrestored or its voltage returns to withinspecified tolerances, the systemautomatically returns to its normaloperating mode described above (onthe condition it did not reach the end ofbattery power). If the end of batterypower was reached (with the resultinginverter shutdown), the rectifier/charger(A) restarts automatically, but theinverter (B) must be restarted manually.The rectifier/charger recharges thebattery (D) which was dischargedduring the mains outage. During batterycharging, light 2 flashes green.The message "BATTERY CHARGING"is displayed, together with the value ofthe recharging current and batteryvoltage.

The battery charge cycle takes place intwo steps (see figure 10):◗ step 1: the battery is recharged at aconstant current limited to 0.1C10 (i.e.1/10th of the battery capacity specifiedfor a 10 hour discharge). The DCvoltage increases with the batterycharge until the charge level isreached;◗ step 2: the battery is recharged atconstant voltage equal to the chargelevel (maximum value 463 V).The charging current graduallydecreases until reaching a specifiedlow value (floating current).For vented lead-acid batteries, therectifier/charger supplies the chargingvoltage for 0 to 255 hours (parameterdefined by the after-sales supportdepartment) and then the floatingvoltage. For sealed lead-acid batteries,the charging and floating voltages arethe same.

Note 1:If the normal AC source failure isshorter than 0 to 255 seconds (defaultvalue = 30 seconds) (parameterdefined by after-sales supportdepartment), the charger automaticallysupplies the floating voltage given thelow battery discharge.

Note 2:In frequency converters without batterypower, the return of normal AC sourcepower results in the automatic restart ofthe rectifier/charger and the inverter.

Operation with bypass ACsource restored◗ no battery discharge (see figure 11).When bypass AC source power supply(2) is restored or returns to withinspecified tolerances, the load istransferred back to the static bypass(C), without an interruption in thesupply of power.

Note: this operating mode does notdepend on the status of the normal ACsource, which may be within or outsidethe specified tolerances.◗ after battery discharge (see figure12).Operation of the rectifier/charger (A)with the battery (D) is identical to thatpresented in the section on on-linemode operation above.

Forced transfer and returntransfer◗ forced transfer. When the load issupplied via the static bypass (C), itmay be transferred to the inverter (B)by pressing pushbutton 20 (see figure19 in the "control panel" section).The message "FORCED TRANSFERTO INVERTER REQUESTED, POWERTO LOAD MAY BE INTERRUPTED" isdisplayed. Confirmation by pressingpushbutton 12 is required to effectivelyforce transfer. The message "LOADFORCED TO INVERTER, ECO MODE"is displayed. Whatever the status of thebypass AC source, a return to normaloperation in "ECO" mode is possibleonly through a forced return transfer tothe static bypass (C).◗ forced disconnection: as the load issupplied by the inverter (B), it can betransferred to the bypass AC source(M2) via the static bypass (C) bypressing the pushbutton 20 . Themessage "FORCED TRANSFER TOM2 REQUESTED, POWER TO LOADMAY BE INTERRUPTED" is thendisplayed. Confirmation by pressingpushbutton 12 is required fordisconnection.

Note:There are two possibilities: the bypassAC source is within tolerances oroutside tolerances. In the first case, theUPS in "ECO" mode returns to normaloperation.In the second case, the transfer willtake place with a power cut to the loadif the bypass AC source is present, orthe load will cease to be supplied if it isabsent. In both cases, the display reads"LOAD NOT PROTECTED, ECOMODE".

Caution:Return to normal operation of theinstallation in the "ECO" mode ispossible only after the bypass ACsource has returned to within specifiedtolerances.

Operation in "ECO"mode

Normal operationSee figure 11.The power required by the load issupplied by the bypass AC source (2),via the static bypass (C). The rectifier/charger (A) supplies the power requiredto float charge and recharge the battery(D).Lights 1 , 3 and 5 shine green andlight 4 flashes green. The message"LOAD PROTECTED, ECO MODE" isdisplayed.

Operation with the bypassAC source outsidetolerancesWhatever the status of the normal ACsource, operation of the rectifier/charger (A) with the battery (D) isidentical to that presented in the sectionon on-line mode operation above.When bypass AC source (2)characteristics are outside tolerances(voltage: ±10%; frequency as perpersonalisation; phase sync withinverter ±3°), the load is supplied viathe inverter (B).From then on, the minimum operatingtime on the inverter (B) is 2 minuteseven if the bypass AC source returns towithin specified tolerances. Refer tofigure 7 in the general appendix if thenormal AC source is present, and tofigure 8 if it is absent. After this 2minute period, the load is immediatelytransferred to the bypass AC sourcewhen the latter returns to withinspecified tolerances.

Note:The maximum transfer time of the loadfrom the static bypass (C) to theinverter (B) is 15 ms.

Parallel UPSs withredundancy◗ the shutdown of one UPS unit is ofno consequence for the load. Theothers each take up an equal amount ofload power and the load continues tobe supplied normally;Unit shutdown results in the followingon the control panel:◗◗ lights 4 and 5 go off,◗◗ activation of the buzzer (continuousbeep),◗◗ the message "LOAD NOTPROTECTED, PARALLEL ON-LINEMODE" is displayed;◗ in the event of an overload, thesystem only loses its redundancy aslong as the overload is less than thetotal rated power of the functioningunits. If the overload is greater, theoperating mode is that previouslydescribed for systems withoutredundancy.

Frequency converters◗ in the event of a shutdown, the loadis no longer supplied with power;◗ in the event of a major transientoverload (greater than 1.65 In), theinverter will current limit to 165% oftheir rated current for 1 second beforestopping;◗ in the event of a smaller butprolonged overload, the inverterrespects the same overload curve asthe single inverter and shuts down;◗ in all three of the above cases,inverter shutdown results in thefollowing:◗◗ lights 4 and 5 go off,◗ ◗ activation of the buzzer (continuousbeep),◗◗ the message "LOAD NOTPROTECTED, ON-LINE MODE" isdisplayed.

Inverter shutdown oroverload

See figure 13 for devices orinstallations operating in on-line modewith a bypass AC source.

If the conditions are not satisfied, theinverter will current limit to 165% of itsrated current for 1 second beforestopping;◗ in the event of a small but extendedoverload (i.e. a continuous level ofpower exceeding the full rated load),the inverter will continue to supplypower for a period depending on themagnitude of the overload (10 minutesfor a 125% overload, 1 minute for a150% overload). See the overloadcurve in figure 14;◗ in all three of the above cases,inverter shutdown and supply of theload via the bypass AC source resultsin the following on the control panel:◗◗ light 4 goes off,◗ ◗ activation of the buzzer (continuousbeep),◗ ◗ light 3 shines green,◗ ◗ the message "LOAD NOTPROTECTED, ON-LINE MODE" isdisplayed.

Parallel UPSs withoutredundancyThe shutdown of one inverter results inoverload on the other inverters inoperation. Two cases may then arise:◗ if the overload on each remaininginverter is > than 1.65 ln, the load isimmediately transferred to the bypassAC source;◗ if the overload is less than 1.65 ln,the remaining inverters support theoverload (see curve in figure 14), andthe load is transferred to the bypass ACsource;◗ after this transfer:◗◗ the light 4 goes off,◗ ◗ the buzzer is activated and soundscontinuously,◗ ◗ the light 3 goes on and turns green,◗◗ the message "LOAD NOTPROTECTED, PARALLEL ON-LINEMODE" is displayed.

Single-UPS unit (on-line or"ECO" mode)◗ in the event of a UPS shutdown(initiated by the user or by an internalprotective device), the load isautomatically transferred to the bypassAC source. If transfer conditions aresatisfied, transfer takes place instantly,without interruption to the load;Note: transfer conditions are notsatisfied when bypass AC sourcecharacteristics are outside tolerances(voltage: ±10%; frequency as perpersonalisation; phase sync withinverter ±3°);◗ in the event of a major transientoverload (greater than 1.65 In),immediate transfer takes place asabove, without interruption to the load.The return to the inverter is automaticwhen the overload disappears if thenumber of possible returns has notbeen reached (0 to 255, programmableby personalisation). If this number hasbeen reached, the load continues to besupplied by the bypass AC source. Thisoperating mode allows start-up of loaddevices causing high inrush currents.This system requires satisfied transferconditions.

Operation with anengine generator set

See figure 15 below.If a stand-by generator is included inthe installation, it is generally startedautomatically in the event of a normalAC source failure and connected to themain low voltage switchboard. It isdisconnected when normal AC sourcepower is restored.With such a system, the requiredbattery time may be reduced to the timenecessary for starting and bringing online the stand-by generator. The battery(D) supplies power to the inverter (B)during the transfers:◗ normal AC source to the generator;◗ generator to the normal AC source.The transfer sequences describedabove (normal AC source ➜ battery,battery ➜ generator, generator ➜battery, and battery ➜ normal ACsource) are fully automatic. They in noway affect the load and require nomanual operation by the user.

Note:To avoid load surges on the generator,the rectifier/charger is started with a 10second maximum current consumptionwalk-in (lasting 3 to 10 seconds,depending on the percent load).To avoid overloading an undersizedengine generator set, it is possible toset a maximum power level drawn bythe normal AC input. Any additionalpower required is supplied by thebattery. This modification can be madeon site by an APC by SchneiderElectric technician.

Fig. 15

Example of an installation with an engine generator set


Output voltage qualityand continuity

The output voltage is stable inamplitude and frequency and is free ofinterruptions or transients outsidespecified tolerances, irrespective ofnormal AC source or load disturbances(outages, load step changes, etc.).

Steady state voltageregulationFor stable or slowly varying loadconditions, the inverter output voltage isregulated to within ±0.5% in amplitude.The frequency of the output voltage cantheoretically be regulated to within0.1% of the rated value, however theoutput frequency range may beintentionally extended to a maximum of±2 Hz so that the inverter can remainsynchronised with the bypass ACsource and its inherent frequencyfluctuations, thus enabling transfer ofthe load to the bypass line at any time.

Note:The output frequency range can bepersonalised and if necessary modifiedon the customer site by a qualified APCby Schneider Electric supporttechnician from ±0.25 Hz to ±2 Hz in0.25 HZ steps.When the bypass AC source voltagemoves outside this frequency range,the inverter is desynchronised andoperates in "free running" mode, withthe output frequency regulated to ahigh level of accuracy by a quartzoscillator.

When the bypass AC source frequencyreturns to within the specifiedtolerances, the inverter is gradually re-synchronised to the bypass line at arate of 0.5 Hz to 2 Hz/s (as per thevalue personalised by the after-salessupport department), thus avoidingexposing the load to sudden frequencyvariations.

Transient voltageregulationThe inverter output voltage is notnotably affected by instantaneousmajor variations in load characteristics.This is made possible by the PWM(Pulse Width Modulation) choppingtechnique and the microprocessor-based regulation system that instantlycompensates for any variation. Inparticular, the inverter output voltageremains within +/- 2% of the ratedvoltage for load step changes of 0 to100% or of 100 to 0%.

General

The autodiagnostic system considersany system status other than normal asa problem.Before taking any action, note downthe messages displayed on the controlpanel.Certain problems may prevent thecontrol panel from functioning.In this case, it is stronglyrecommended to call the APC bySchneider Electric after-salessupport department.◗ If the load is still correctly suppliedwith power, it has probably beentransferred to the bypass AC source(static bypass) and is therefore nolonger protected (if the system is in on-line mode);◗ if the load is no longer supplied withpower, transfer it manually to themaintenance bypass (see sectionbelow).

Alarms

Maintenance bypass

This operation is possible only if thesystem includes a bypass AC source.It results in the load being directlysupplied by the bypass AC source viamaintenance bypass switch Q3BP, thusensuring a higher level of security in theevent of a malfunction.Switching procedures are explained ondrawings next to each switch in theUPS cubicle and the external bypassunit. See section "maintenanceconfiguration".

The signals should be provided by volt-free contacts.◗ emergency off:An NC contact causes shutdown of theinverter and the rectifier/charger,opening of the battery circuit breakerand activation of a relay contact on the"Media Contacts 11" board;◗ battery room ventilation fault:An NO contact causes shutdown of therectifier/charger;◗ battery circuit breaker QF1 closed:An NO contact prevents inverter start-up if the circuit breaker is open;◗ battery temperature:A PC-board, placed near the battery,supplies information on the batterytemperature, thus enabling the rectifier/charger to regulate the battery voltage;◗ "auxiliary" signals:Depending on the selected settings,these signals may be used to provoke:◗◗ forced shutdown of the inverter(whatever the status of the bypass ACsource),◗◗ protected shutdown of the inverter(load transfer to the bypass ACsource),◗◗ a change in the inverter outputfrequency (50 Hz or 60 Hz).◗ ◗ limiting of the current drawn by therectifier/charger (programmable value)when supplied by an engine generatorset with an insufficient power rating.The additional power required by theinverter is supplied by the battery whichdischarges,◗ ◗ limiting of the battery charge current(programmable value) if the normal ACsource is replaced by an enginegenerator set with an insufficient powerrating.

Signal transmission

◗ an auxiliary 24 V power supply,isolated and backed up, is used tosupply:◗◗ the undervoltage release of thebattery circuit breaker(s) QF1,◗◗ the board that measures thetemperature in the battery room;◗ "low battery" warning signal (volt-free changeover contact) indicating thatbattery time is about to run out. Thewarning threshold may bepersonalised;◗ "load on UPS" signal (volt-freechangeover contact) indicating that theload is supplied by the inverter. For asingle-UPS unit, one volt-freechangeover contact may be used toindicate that the load is supplied by thebypass AC source;◗ "load on battery power" signal(volt-free changeover contact)indicating that the inverter is suppliedby the battery in the following cases:◗◗ normal AC source outage or voltagedrop,◗ ◗ rectifier/charger shutdown,◗◗ rectifier/charger current limiting.This signal, which may be used toinitiate process saving and shutdownprocedures, is time-delayed 30seconds to avoid unnecessaryoperations following micro-breaks;◗ "maintenance position" signal(volt-free changeover contact)indicating that:◗◗ maintenance bypass switch Q3BP isclosed,◗ ◗ bypass AC source input switch Q4Sis open,◗ ◗ inverter output switch Q5N is open,◗◗ battery circuit breaker QF1 is open;

The backup time is the valuecalculated by the UPS microprocessoron the basis of measurements carriedout on the battery. It is expressed inminutes. The calculation uses thepercent load and the battery chargestatus at the time of the measurement.

The load level is the ratio between thepower supplied by the UPS to the loadat the time of the measurement and therated output of the UPS. It is expressedas a percentage.

The battery capacity is the valuemeasured by the UPS microprocessor.It is expressed in Ampere-hours.This value changes over timedepending on the parameters of thebattery itself and its environment.This measurement is used to checkthat the battery is capable of supplyingthe rated power in the event of a mainsoutage.

Battery maintenance

Consult the instructions supplied by thebattery manufacturer. Below are a fewgeneral indications:◗ sealed lead-acid batteries: thesebatteries require no maintenance, butcheck the terminals of each cell fromtime to time and clean if necessary;◗ vented lead-acid batteries:◗◗ check the electrolyte level regularlyand add water if necessary,◗◗ check the voltage of each cell todetermine if it is necessary to equalisethe battery,◗◗ check the terminals of each cell andclean if necessary.

Caution:Battery maintenance is undertaken withthe system powered up. Operationsmust be carried out in accordance withapplicable safety regulations byqualified personnel using insulatedtools, gloves and safety goggles.Batteries contain dangeroussubstances that will harm theenvironment if thrown away. If youchange the batteries yourself, call onqualified organisations for batteryrecovery and recycling.

Visual check

◗ Power down the system prior to anymaintenance operations.Note: in redundant, parallel UPSsystems and frequency converters, thecheck may be carried out successivelyon each UPS unit without interruptingthe load. In other configurations, theload must be supplied via themaintenance bypass (see"maintenance bypass" in the "Alarm"section);◗ clean the system regularly,particularly the air inlet and outlet grills.Check that the air circulates freely inthe cubicles. Use a vacuum cleaner ifnecessary;◗ check that nothing hinders theventilation at the top and at the back ofthe system;◗ check that all the fans operatecorrectly.

Functional check

◗ Check that lights 1 , 2 and 3 onthe control panel are not red, to avoidan interruption in the supply of power tothe load due to incorrect transferconditions or a battery problem;◗ press the "inverter OFF" button andcheck that the buzzer and control panellights function correctly (see the sectionon operating modes in the introduction);◗ press the "inverter ON" button andcheck again that the control panel lightsfunction correctly;◗ run a transfer to battery test. With theinverter on, open input switch Q1. Theorange "battery" light on the controlpanel should light. After two minutes onbattery power, close input switch Q1.The rectifier/charger shouldautomatically restart and the orange"battery" light on the control panelshould go off;◗ in parallel systems, run these testson each UPS unit.

Harmonics filter andpower factorimprovement

This option, placed on the normal ACinput upstream of the UPS in the 1.9meter high UPS cubicle for UPSs up to120 kVA and in an auxiliary cubicle forhigher ratings, reduces the reinjectionof harmonic currents into the normalAC source. Harmonic reinjection,produced by the rectifier/charger,increases distortion on the normal ACsource. The amount of the increasedepends on the source impedance.The reduction in distortion reduces therisk of disturbing other sensitive loadsconnected to the mains. The filter canalso increase the power factorupstream of the inverter.Three types of filter are available:◗ uncompensated filter for theadvantages listed above;◗ compensated filter for theadvantages listed above and to limit thecapacitive current absorbed by the filter(additional inductance), in the event theUPS is supplied by an engine generatorset;◗ active harmonic conditioner, the mosteffective solution because it providesthe harmonics drawn, thus allowing thenormal AC source to supply a perfectlysinusoidal current. The conditioner maybe installed in an auxiliary cubicle orwall-mounted.

Isolating and voltagematching transformerfor the normal andbypass AC source andthe load

This transformer, placed in the 1.9meter high UPS cubicle up to 60 kVAand in an auxiliary cubicle for highervalues, may be used to match thebypass AC voltage to that of theinverter, to create galvanic insulationbetween the load and the Ac sources orto create the appropriate systemearthing arrangement.

Options

Safety of life andproperty

◗ backfeed protection. This option,installed upstream of the static bypass,is used to mechanically disconnect thebypass AC source when the systemhas shifted to battery power or whenthe bypass AC source has failed. Thissystem is intended to enhance thesafety of life and property.
