The following graphic shows you the components of the kits for the wye-
delta combinations in frame sizes S6 to S12 and explains how to put it
together
Drawing: Frame size S6 - S6 - S6 Step Procedure
1/2 Mount the wye-delta com-
bination to the mounting
plate.
3/4 Set the bottom wiring mod-
ule in place and tighten
down them to the main
connections.
5/6 Set the wye-jumper in
place tighten down them to
the main connections.
7/8 Push in the “push-in lugs” for
panel mounting the timing
relay and then screw mount
the timing relay to the
mounting plate.
