Drawing: Frame sizes S10 (S12) - S10 (S12) - S6 (S10) Step Procedure
1/2
Mount the wye-delta com-
bination to the mounting
plate.
3/4
Wire the main current
paths of the delta contactor
and the wye contactor and
tighten down the main con-
nections.
5/6
Set the wye-jumper in
place and tighten down the
main connections.
1/2/3 Push in the “push-in lugs” for
panel mounting the timing
relay and then screw mount
the timing relay to the
mounting plate.
