Sincro HB4 - 6 Installation; Lifting; Mounting on Engine

6. INSTALLATION
6.1 Lifting
Liftandhandlethegeneratorwithsuitableequipment
eitheron a palletorby the liftinglugs locatedonthe
generatorinthepositionsindicatedinthefigure.
When lifting the HB generator use equipment with a
load bearing capacity of at least 200kg.
When lifting the IB generator use equipment with a
load bearing capacity of at least 300kg.
Whenliftingandhandlingsinglebearinggeneratorsthey
mustbekepthorizontalinordertoavoid,ifoperations
shouldgowrong,therotorfromslippingoutandbeing
damagedandpossiblycausingsevereinjury.
6.2 Mounting on engine
Fortighteningtorquesrefertosection6.2.3.
Formechanicalconnectionsitisrecommendedtouse
screwsinclass8.8.
canopyshouldbedesignedsothatthereisaminimum
clearanceof50mmbetweenthegeneratorairventand
anyflatsurface. 
Thespacearoundtheairexitprotectiongridmustbe
free.
Thegenerator’srotorisdynamicallybalancedinfactory.
Theengineinducesquitecomplexvibrations,including
harmonicswithdifferentfrequencythat,whenaddedto
thegeneratorvibrations,cancausesubstantialvibration
levels dangerous for the generating set operation.
Thereforeitisessentialthattheplantengineertakesall
necessarymeasurestoensurealignmentandprovide
afirmbaseandsupportsinordertopreventvibrations
fromexceedingthestandard.
The alternator is designed to work with vibration’s
valuesasreportedinISO8528-9.
Alignment of single bearing generators is critical
becauseitmaygiverisetovibrationsalongthecoupling
betweenengineandgenerator.Forthispurposespecial
attention must be given to the alternator to engine
assembly, providing a solid base and implementing
anti-vibrationdamperstosupporttheengine/alternator
assembly.
Dual bearing generators require a rigid frame to
support theengine/generator so that a good base is
establishedforaprecisealignment.Thisframeshould
beanchoredtothebasewithanti-vibrationdampers.In
ordertominimizetwistoscillations,itisadvisabletouse
asuitablysizedflexiblejoint.
Inbelttransmissionsappliedtodualbearinggenerators
itisessentialthatthepulleydiametersandconstructions
permittheloadappliedtotheshafttobecentredwith
the length of the nub. The acceptable loads can be
requesteddirectlytotheSincro Technical Office.
Theterminalboxcontainstheinsulatedterminalsfor
connecting thephases and neutral and for the earth
connection.
The neutral is NOT connected to the housing.
Thegeneratorfaultcurrentsareavailableonrequest
to help the plant engineer in sizing the plant and its
components.
A drop in cooling air ow or inadequate
protection of the generator can lead
to damage and/or malfunction of the
windings.
WARNING!
The generator is supplied without
a connection to earth; to make this
connection refer to relevant local
regulations.Anine󰀩cientearthconnection
orsafetycut-outcancauseinjuryordeath.
WARNING!
Anerrorininstallation,use,maintenance
orreplacementofpartscancausesevere
injuryordeath,nottomentiondamageto
themachinery.Allworkonelectricaland/
or mechanical partsmust becarried out
byaqualiedspecialist.
WARNING!
An insu󰀩cient loadbearing capacity can
causesevereinjuryanddamage.
CAUTION!
Theliftinglugsonthegeneratorhavebeen
designedforliftingonlythegeneratorand
notthewholegeneratingset.
CAUTION!
Beforeassembly,checkthatthecoupling
seats(bothongeneratorandengine)are
inorderandperfectlyclean.
CAUTION!
