Direct-On-Line and Automatic Star – Delta Starter

Our new series of DOL and ASD starters complies to latest 
standard IS/IEC 60947-4-1

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 fitted 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, 

the coil voltage corresponds to 
actual supply voltage.

•  Inspect interior for breakage.
•  If you find a serious defect, do 

not use the product but have 
it checked by an authorized 
Siemens dealer or an 
electrician.

Installation:

•  As soon as you open the 

starter, you will see a sticker 
“K1 BIRELAY” showing the 
location at which the relay 
should be mounted. Refer 
Table 5 for the procedure to 
be followed for fitting the 
relay.

•  Complete the wiring by 

connecting the wires having 
ferrules ‘95’ and ‘96’. Wiring 
should be exactly as per the 
circuit diagram label shown 
on inside of the front cover. 

•  Back up fuse ratings and cable 

sizes are also recommended 
on the label. Also for your 
future reference, space is 
provided on the label inside 
the front cover to write the 
coil voltage and the relay 
range selected by you.

•  In case of starters having 

resetting cord, attach the 
resetting device on the holes 
provided on the relay surface. 
(ref. fig. 4) Adjust the end 
of the reset cord using the 
adjustment screw (fig. 4) so 
that clearance between blue 
knob and reset cord metallic 
end is about 2mm.
