Crompton Controls 3DS1- -I - Manual (Page 2)

Unscrew the Contactor male terminal screws until the
clamps are fully open.
Attach the start push button contact block to the
overload as shown in the sketch below.
When correctly located only a very light force is
required to clip the block into position.
Align the overload pins according to the contactor
selection. Fit the overload pins into the contactor
terminals and tighten the terminal screws, ensuring
that all three pins are underneath the terminal clamps.
Most parts of the starters are not regarded as
serviceable items and therefore, in general, complete
components are required. The following list gives a guide
to the parts which are available and the information
required when ordering replacement parts.
In order to ensure that the correct parts are supplied
please quote the details given on the starter rating plate
and the details given on the component rating plate along
with the information shown alongside the description.
