Operating Instructions
Selection:
• ReferTable1forrecommended
selectionofDOLStartersand
Table2forASDStarters.
• DOLandASDStartersare
suppliedwithoutrelays.Relays
aretobettedatsite.
• Selectthesuitablerangeof
relayasperrecommendation
giveninTable1and2.
• Selectback-upfuserating
fordifferentstartersfrom
theselectiontables.The
recommendationofthefuses
andfuseswitchesisaccording
toType-2co-ordinationasper
IS/IEC60947-4-1.
Inspection:
• Removethehousingcover.
• Checkthecoilvoltagessothat,

• In case of DOL starters
under no circumstances
should the relay be set
higher than the rated
current on the motor name
plate.
• In case of ASD starters
under no circumstances
should the relay be set
higher than phase current
i.e. 0.58 times the rated
current on the motor
nameplate.
• Iftherelaytripsevenwhen
set at the rated motor
current the suitability of
the starter / relay for the
particular application should
be checked with the nearest
Siemens office.
