Kits The following graphic shows you the components of the kit for the wye-
delta combination in frame size S00 and explains how to put it together:
Drawing: frame size S00 Step Procedure
1/2/3 Place the mechanical interlock
in the opening on the right
side of the delta contactor K3.
Push the wye contactor K2
and the delta contactor K3
together.
4/5 Press a connecting clip for
both the top and bottom onto
the two contactors (3).
Make sure the clips are on the
correct side.
6/7 Break the upper link module
off at the notches (6), and
attach the wiring modules and
the wye jumper, to connect
the main conducting paths
(between line contactor (K1)
and delta contactor (K3) and at
the same time to interlock the
combination electrically
(K3-K2)).
8/9 Wire A2 and tighten the termi-
nal screws.
