Unprotectedmachinedsurfaces(shaft-endsandflanges)
shouldprotectedwithanti-corrosivepaint.
Itisrecommendedthatshaftsberotatedperiodicallyby
handtopreventgreasemigration.
Anticondensationheaters,iffitted,shouldpreferablybe
energised.
Thecharacteristicsofelectrolyticcapacitors,iffittedto
single-phasemotors,willrequire“reforming”following
periodsofstorageexceeding1-2years.

arrangementsandaddedfeatures.
Thefollowingtableshowsestimatedmaximumweights
formachinesintheirbasicversionsasafunctionofframe
