Othermotor‐drivenpartsaredamperswithdampermotorsandrotaryheatexchangers,butthemovement
issoslowthatguardmeasuresarenotnecessary.Justkeepyourhandsawayfromplaceswithriskofinjury.

s.1.1Necessaryprotectionmeasurespriortostart‐up.
Ensurethatallprotectionmeasuresareinstalledcorrectbeforestart‐up.
s.1.1.1Designofprotectionmeasures
Insidethedoorsareadditionalprotectioninstalled–guards thatonlycanberemovedbyuseoftools.
s.1.1.2Configurationoffrequencyconverterswithinstalledguard
Afrequencyconverterismountedbesidethefanin
someunits.Iftheconfigurationoffrequencyiscarried
outwiththefaninoperation,theguardmustbeinstalledforsafetyreasonsandalongcablemustbe
installedbetweenthefrequencyconverterinsidetheunitandthecontrolpaneloutsidetheunit.
s.1.2Safeadjustmentandmaintenance
Beforemaintenanceandrepair,theunitmustbeswitchedoffbyswitchingofftheautomaticcircuit
breakersandblockthembypadlocks.TheautomaticcircuitbreakersaremarkedF1toF4.Seethe
illustrationbelowabouthowtoplaceapadlockoneachautomaticcircuitbreaker.Checkthatthe
automaticcircuit
breakermarkedF5isstillswitchedonbecausethelampsinsidetheunit,andonlythose
lamps,areconnectedtothisswitch.Switchonthelampsforlightduringthemaintenanceactivities(note
thatthelampsareanaccessory–onlyinstalled,ifordered).
Usecut‐resistantglovesforprotection
againstinjuryfromsharpmetalplateedges.UseCE‐markedgloves
forthispurpose.Usehelmetduringmaintenanceworkintheunit.

s.1.3Personalprotectiveequipmentformaintenancestaff–healthandsafety
Usethebelow‐mentionedpersonalprotectiveequipmentformaintenance:
 Cut‐resistantglovesforprotectionagainstinjuryfromsharpmetalplateedges.UseCE‐marked
glovesforthispurpose.
 Helmet
 Particulaterespirator–maintenancefreeincludingfoamface‐sealandadjustablepre‐threaded
headbands–forreplacingfilters.

Padlockforlockingtheabovementionedautomaticcircuitbreakers.
 Permanentmagnetmotor.Theshaftmustbeblockedduringrepairsandmaintenanceofthe
electricsystem(themotorgenerateselectricitybyrotation–forexamplethatthewindand
thermicdrivesthefan/motor).
