•It isforbidden to storeEAoutsideorin areasnot prevented againstdirectimpact ofclimate.
•Strainsofthe surface finishing should be promptlyremoved ifany– itcan prevent the product against
corrosion damages.
•While storing more than oneyearitisnecessarytochecklubrication filling before the actuatorisput into
operation.
•The EA installed but not operated are to beprotected the same wayaswhen storing (e.g.with a
wrapping).
•Afterit ismounted onto a valvein free and wet areasorinareaswhere temperature ischanging itis
necessarytoconnect the space heater– to preventthe actuatoragainst corrosion resulted fromwater
condensed in the controlpart.
•Remove odd conservation grease aslate asbefore putting into operation.

Follow safetyregulations!
Note:
Check againwhethertheEA isplace inaccordance withthe Chapter“Operation Conditions”. If
the installation conditions aredifferent than recommendedit isneededtoconsult thesituation withthe
producer.
Beforestartingthe installation ontothevalve:
•Check againwhethertheEA was not damagedwhilestoring.
•Check compliance of thestrokeadjusted bythe producerand the connecting dimensions oftheEA
withtheparametersofthevalve.
•Incaseof anydifferenceperformthe adjustmentaccordingtothe Chapter“Adjustment”.

3.1.2ElectricConnection withMainsor Checking ofFunctions
Followup withconnecting theEA withmains ormastersystem.
1. Followinstructionsgiven in the Chapter“RequirementsforProfessionalQualification...“!
2. Whilelaying electricwiring follow instructionsforheavy-current appliancesinstallations!
3. Cablesshould be brought to terminalboardsorconnectors with cable screwed bushings!
4. Beforethe EAisput into operation jointheinternaland externalearthling terminals!
5. The inlet cablesshouldbe fixed onto afixed construction max. 150 mm from the bushings!
Connecting withthemastersystem:
The EA canbe controlledwith:
-a built-in position controller
-an externalposition controller
1. If the EA iscontrolled with an externalcontrollerusing unifiedsignalfrom a two-wire transmitter
(capacitiveorresistivewitha converterin two-wire connection), itisneeded to arrangeconnecting
of the two-wire transmitterloop to electricalearth ofthe successive externalcontroller!
2. Connection can be performed onlyin one point, inanypart ofloop out of theEA.
3. Electronics of the two-wire transmitters isgalvanically insulatedthat iswhyit can serve asan
externalsource forsupplying of severaltransmitters (theirnumberdependson current which the
source can supply).
Connecting toterminalboard
Checkwhetherthe type ofcurrent, supplyvoltageand frequencycorrespond with dataon the nameplate of
electricmotor.
Remove the uppercover.
In case ofthesingle-phaseversion the phase L1 and the leadN,, the protection cablesto the marked placesof
internaland externalprotectionterminals.
Connect thecontrolcablesaccordingto the wiring diagramplaced into the internalside ofthe cover.
Put the coveron and tighten ituniformlycrosswisely.
Tighten the cablebushingsfirmlyto assure the protection enclosure rate.
Notes:
1. The EAare delivered with bushings, whichin caseof tightputting on the leadsassure protection enclosure
up toIP68. Forrequiredprotection enclosureitisneeded to use ringsaccordingto the actualcable
diameter.
2. While fixing the cableitisneeded tocountwith allowed bend radiusto avoiddamaging ordeformationof the
sealing element ofthebushing.The leadsare to be fixed with the solid construction atmost150 mm from
the bushings.
3. It isrecommended to use screened cablesto connectremotetransmitters.
4. The faceareasof the controlpart coverhaveto be before re-mounting clean, coated with a grease without
anyacid(e.g. vaseline)andsealing not damaged to avoidjoint corrosion.
5. Reversation oftheEAissure, if the period between switching-off and switching-onof powersupplyforthe
reversed movementof the output part isminimally50 ms.
6. Delayafterswitching-off,i.e. time since a reaction of switchestillthe motorisdead can be maximally20 ms.
7. It isrecommended to havethe corresponding directionprotection switched-off directlywiththe
corresponding position ortorque switches.

Afterelectricconnectionperformcheckingoffunction:
Put the valvemanuallytoamid-position.
Connect the EAelectricallyfor the chosen direction ofmovement and watch the output part movement.
Ifit does not correspond changethe order offeedingphases (validfor 3x400Vversion), or change leadsof
the feeding phase tothe corresponding terminals(validfor 230Vversion).
Checkthe controlunit switches connectionwithswitchingconsequentlythe contactsofthe corresponding
switches withpressing the controlelementsat running ofthe EA (at proper connection) tothe chosen
